For an Australian small business in late October 2026, the best AI chatbot is not one product. It is a short list of six, and the right pick depends on which software your staff already live in. If your team runs Google Workspace, Gemini 4 Argon is the obvious first test. If you run Microsoft 365, Copilot is hard to beat on integration. If you want the strongest general writing and coding assistant on one card, ChatGPT and Claude trade the lead depending on the task.
The model race moved fast this month. Google made Gemini 4 Argon available to everyone on 13 October 2026, with the Gemini app and AI Mode in Search open to Google AI Pro and Ultra subscribers. OpenAI followed with GPT-6.1 Sol, Anthropic with its Claude 5.5 family, and xAI with Grok 4.7. This article compares all six chatbots on what a five-to-fifty-person Australian firm actually cares about: monthly cost, which tools they plug into, how safely they handle customer data, and how hard it is to switch. For a wider ranking built around consumers, see our best AI chatbots ranking for Australians.
One honest caveat up front. Every vendor in this comparison publishes prices in US dollars on its official pages, and none of the pages we checked on 23 October 2026 showed a confirmed Australian dollar figure. Your final price depends on the exchange rate, GST, and whether you buy through a website or an app store. We quote US dollars throughout and flag anything that needs checking at your own checkout. We also did not find verified, current head-to-head benchmark scores for the newest models, so we say so in the benchmarks section instead of inventing numbers.

Best AI Chatbot for Small Business: The Short Answer
Here is the verdict in one table, before we get into detail. Each pick names the product line, the model it currently runs, and the kind of business it suits best. These are editorial judgements built on the official product pages and the facts we could verify, not lab scores. We left Meta AI out of the ranking because we could not confirm any current model, plan or price for it on the day of writing.
| Business need | Best pick | Current model or line | Why it wins |
|---|---|---|---|
| Best all-rounder | ChatGPT | GPT-6.1 Sol | Widest plan ladder, from free to business seats, and a model family tuned for coding and professional work |
| Best for writing and long documents | Claude | Claude 5.5 (Opus, Sonnet, Haiku) | Anthropic positions Opus 5.5 for agentic coding and knowledge work, at 40% lower running cost than Opus 5 |
| Best for Google Workspace shops | Gemini | Gemini 4 Argon | Built into the Gemini app and Search AI Mode, with a 95% discount on cached API input |
| Best for Microsoft 365 shops | Microsoft Copilot | Redesigned Home, Code and Autopilot | Copilot Chat costs nothing extra for eligible Microsoft 365 users |
| Best for real-time and social | Grok | Grok 4.7 | Cheapest entry plan of the group at US$8 a month through The X Subscription |
| Best for research with sources | Perplexity | Multi-model search platform | Search-first design that routes to several third-party models |
If you only have time to test one, test the chatbot that sits inside the software your team opens before 9am. A tool that lives in your inbox and documents gets used. A tool that needs a separate browser tab gets forgotten after week two. We expand on that reasoning in the verdict, and our three-way flagship comparison of Claude Opus 5.5, GPT-6.1 Sol and Gemini 4 Argon goes deeper on the raw model gap if raw capability is your main question.
Specs Table: Six AI Chatbots Side by Side
The table below lines up the six products on twelve attributes. We only list what the vendors’ own pages confirm as of 23 October 2026. Where a vendor has not published a figure we could verify, the cell says so. That gap is itself useful information, because a small business owner comparing plans should know which prices are easy to find and which are buried.
| Attribute | ChatGPT | Claude | Gemini | Copilot | Grok | Perplexity |
|---|---|---|---|---|---|---|
| Maker | OpenAI | Anthropic | Microsoft | xAI | Perplexity | |
| Newest model named | GPT-6.1 Sol | Claude 5.5 family | Gemini 4 Argon | No single model named | Grok 4.7 | Multi-model |
| Free tier | Yes | Yes | Yes (Gemini app) | Copilot Chat with eligible Microsoft 365 | Yes, limited | Yes |
| Entry paid plan (USD per month) | Plus, US$20 | Pro (see claude.com/pricing) | Google AI Pro (not confirmed in USD) | Bundled with Microsoft 365 | Plus, US$8 | See text below |
| Higher consumer tiers | Pro 100, 200, 500 | Max 5x and 20x | Google AI Ultra | Higher Microsoft 365 plans | Premium US$30, Super US$100, Ultra US$200 | Max |
| Business plan | Business and Enterprise | Team and Enterprise | Gemini for business | Microsoft 365 Copilot | Team seats on The X Subscription | Enterprise plans |
| Flagship API price (input / output per million tokens) | See pricing section | See pricing section | US$2 / US$10 intro, then US$4 / US$20 after 30 Nov 2026 | Metered via Azure | US$2 / US$6 | Not applicable |
| Context window noted | Not confirmed | Not confirmed | Not confirmed | Not confirmed | 500,000 tokens | Depends on model |
| Lives inside | ChatGPT app, Work, Codex | Claude.ai, Claude Code | Gemini app, Search AI Mode, Android Auto | Word, Excel, PowerPoint, Outlook, Teams | X, grok.com, Cursor | Web and desktop |
| Agent feature | ChatGPT Work and Codex | Claude Code | Google Antigravity | Copilot Studio, Cowork | Grok Bot | Computer |
| Main limit for Australian buyers | Prices shown in USD | Prices shown in USD | Argon needs Pro or Ultra in the app | Some usage-billing changes exclude Australia at first | Plans bundled with X | Top models gated to Max |
| Best fit | Generalists | Writers and developers | Google Workspace teams | Microsoft 365 teams | Social and real-time use | Researchers |
Two rows deserve a closer look. The flagship API row shows how close the big labs now sit on price. Google’s introductory Argon rate and xAI’s Grok 4.7 rate both start at US$2 per million input tokens, so for a business building a customer-facing bot the decision rarely turns on the price list alone. And the “main limit” row is the one most reviews skip. Microsoft has said the usage-based billing change for new Copilot Business licences bought through its partner channel on 1 December 2026 will initially leave Australia out, according to the roadmap notes we reviewed. Check that with your Microsoft partner before you budget.
ChatGPT With GPT-6.1 Sol: The Broadest Plan Ladder
ChatGPT remains the default answer when a business owner says “I want an AI chatbot”, and OpenAI’s current lineup explains why. According to OpenAI’s plans and pricing page, the individual ladder runs Free, Go, Plus and Pro, with Business and Enterprise above that. OpenAI describes GPT-6.1 as the latest model family in the GPT-6 series, and says GPT-6.1 Sol delivers near-Astra intelligence for coding, computer use and professional work at one-fifth of Astra’s standard API token prices.
The naming takes a minute to untangle. OpenAI’s own guidance is to start with GPT-6 Astra for complex reasoning and coding, choose GPT-6.1 Sol to balance intelligence and cost, and use GPT-6 Luna for cost-sensitive, high-volume work. For a small business, Sol is the sensible daily driver. The pricing page shows it as available on Plus and with expanded access on Pro, but marked unavailable on Free and Go. In practice that means the free plan and the cheapest paid plan run on the older GPT-5.6 Luna by default, which OpenAI’s help documentation confirms.
What the Plan Ladder Costs
ChatGPT Plus costs US$20 a month. The Pro tier now comes in three sizes, Pro 100, Pro 200 and Pro 500, priced at US$100, US$200 and US$500 a month respectively. Only Pro 500 includes the Ultrafast variant of GPT-6.1 Sol. Customers who qualified for grandfathering keep their previous Pro 200 allowance for a limited window, after which the allowance changes while the price stays at US$200 a month. For a small business, Pro 100 and above are rarely worth it unless one person lives in the tool all day on agentic coding work.
On the team side, OpenAI’s business pricing reportedly lists a Standard seat at US$20 a month billed annually or US$25 billed monthly, and a Premium seat at US$100 or US$125. We treat those as a single-source figure and suggest you confirm them at checkout. Note that the returned pages do not show an active “ChatGPT Team” plan, so older guides that recommend Team are out of date. Registered nonprofits can claim up to a 75% discount on Business or Enterprise through OpenAI for Nonprofits, which matters to the many Australian charities and community groups running lean.
Where ChatGPT wins is breadth. It handles drafting, spreadsheets, image generation, voice and agent-style tasks through ChatGPT Work and Codex in one subscription. Where it loses is focus, since the product surface changes monthly. A locked-chats feature that protects conversations with a PIN or biometric began rolling out on 20 October 2026, according to a dated report, which is a small but real privacy gain for shared devices. If you want the free-tier view across ChatGPT, Gemini and Claude, our free-tier comparison of ChatGPT, Gemini and Claude covers what you get for nothing.
Claude 5.5: Best for Writing, Analysis and Careful Work
Anthropic’s Claude 5.5 family is the newest generation on the company’s plans and pricing page, with three sizes. Anthropic says Claude Opus 5.5 leads in agentic coding and knowledge work and costs 40% less to run than Opus 5 on typical workloads. It describes Claude Sonnet 5.5 as a clear upgrade over Sonnet 5 that runs more than 30% faster and costs up to 30% less for most work. Claude Haiku 5.5, announced on 7 October 2026, is the small and fast option for high-volume jobs such as summarising, subagents and browser use.
For a small business the practical question is which size to use. Sonnet 5.5 is the everyday workhorse for emails, proposals, contracts review and reports. Opus 5.5 earns its higher cost on difficult analysis and on code. Haiku 5.5 suits bulk tasks such as tagging support tickets or summarising meeting notes, and its published API rate of US$0.10 per million input tokens and US$0.50 per million output tokens (for prompts up to 100,000 tokens) is the cheapest flagship-family price in this comparison. Treat that rate as single-source until you see it on Anthropic’s pricing page yourself. Anthropic also offers a fast mode for Opus 5.5 that runs up to 2.5 times faster at twice the standard price, and a 50% saving for batch processing.
Claude Plans and Team Credits
Claude’s named tiers are Free, Pro, Max, Team and Enterprise. Max comes in 5x and 20x usage sizes. Anthropic’s pricing page lists pooled API credits of up to US$500 a month for Team subscribers and US$100 to US$200 a month for Max users, though the page does not make clear whether these are permanent entitlements or a promotion, so ask before you rely on them. We did not find a confirmed USD price for Claude Pro in the pages we could verify, so check the live page. For a head-to-head on cost and scores between the two biggest names, see our Claude vs ChatGPT pricing and benchmarks comparison and the broader ChatGPT vs Claude guide.
Two newer additions are worth a mention. Claude Design entered research preview on 1 October 2026 for Pro, Max, Team and Enterprise subscribers, and Anthropic introduced Claude Duet, a proactive assistant app, as a research preview on 21 October 2026, according to a dated report. Both are early. A small business should pilot them on non-critical work, not rebuild a workflow around them.
Gemini 4 Argon: The Natural Fit for Google Workspace Teams
Gemini is the chatbot with the clearest advantage for businesses that already run Gmail, Docs, Sheets and Drive. Google says Gemini 4 Argon reached global availability on 13 October 2026 through the Gemini API and Google AI Studio, and for Google AI Pro and Ultra subscribers in the Gemini app and AI Mode in Search.
Google’s consumer subscription ladder now has three tiers: Google AI Plus, Google AI Pro and Google AI Ultra. Its plan page, updated on 22 October 2026, says AI Plus includes 400 GB of storage and AI Ultra starts at 20 TB. We could not confirm Australian dollar prices for any tier, so price the plan at checkout. One catch for small business owners on the free tier: Argon in the Gemini app is a paid-subscriber feature, so free users will not see it yet. Google’s plan page also still mentioned the older Gemini 3 Pro as available in select countries, a reminder to check which model your plan actually runs.
The developer price is the other headline. Google set an introductory rate of US$2 per million input tokens and US$10 per million output tokens, with cached input discounted by 95%. After the introductory period expires on 30 November 2026, the public rate rises to US$4 and US$20. If you plan to build a customer service bot or document pipeline on Argon, lock in your usage tests before the price steps up. Google also promoted new Gemini tools for small businesses between 20 and 23 October 2026, including product-launch and recurring-campaign materials supported by its Nano Banana 2.1 image model. Those tools are early, but they show Google is aiming squarely at this audience.
Microsoft Copilot: The Default for Microsoft 365 Offices
Copilot is a product family, not a single chatbot, and that confuses buyers. In a September 2026 post on building the system for AI at work, Microsoft laid out its direction, and on 25 September it announced a redesigned Copilot organised around Home, Code and Autopilot. For a small business the relevant pieces are Copilot Chat, Microsoft 365 Copilot, Copilot Studio and the newer agent feature called Copilot Cowork.
The best news for small firms is the free layer. Microsoft says Copilot Chat is available at no additional charge to Microsoft Entra ID users with an eligible Microsoft 365 subscription. If you already pay for Microsoft 365 Business, your staff may have a capable chatbot today without a new invoice. The catch is that agents need an Azure subscription and their usage is metered. Microsoft describes Copilot Credits as a shared usage currency for agentic features, including Cowork, and reportedly prices pay-as-you-go use at US$0.01 per credit. That is a shift away from flat per-seat pricing, and it makes monthly cost harder to forecast.
Pricing and the Australia Wrinkle
Microsoft’s US pricing pages reportedly show Microsoft 365 Business Standard with Copilot at US$23.50 per user per month paid yearly and Business Premium with Copilot at US$32, but the same page marked at least one of those products unavailable in the selected market. We found no Australian dollar figures. Microsoft also announced on 23 October 2026 that from 1 December 2026, new Microsoft 365 Copilot Business offers can be bought without a qualifying Microsoft 365 base subscription. Its usage-based billing change for new licences bought through the partner channel will initially exclude Australia. Until Microsoft publishes local pricing, get a written quote from your reseller.
Microsoft’s own roadmap notes say GPT-5.6 powers Word, Excel, PowerPoint, Copilot Chat and Cowork, so Copilot is currently one generation behind OpenAI’s newest Sol model in its flagship Office apps. Microsoft also says it was named a Leader in the 2026 Gartner Magic Quadrant for AI-Augmented Low-Code Application Platforms and in The Forrester Wave for AppGen and Low-Code Platforms in Q4 2026, which speaks to the Copilot Studio side of the business more than the chat window. For a three-way view that includes Meta, read our Microsoft Copilot vs Gemini vs Meta AI comparison.
Grok 4.7 and Perplexity: The Specialist Picks
These two products are not trying to be your all-purpose assistant, and a small business gets the most from them when it uses each for a narrow job. Grok suits fast, conversational work tied to what is happening on social platforms. Perplexity suits research where you need sources you can click and check.
Grok 4.7 and The X Subscription
Grok 4.7 reached the xAI API by 15 October 2026. xAI documentation lists a 500,000-token context window, text and image input, and a flagship API price of US$2 per million input tokens and US$6 per million output tokens for prompts under 200,000 tokens. The company restructured its consumer plans on 12 October 2026 into The X Subscription, which bundles Grok, the Cursor coding tool and X benefits. The verified tiers are Free at US$0, Plus at US$8 a month, Premium at US$30, Super at US$100 and Ultra at US$200, with annual rates available. Grok Bot, xAI’s AI teammate for customer-support work, comes with Premium and above but not Plus.
On xAI’s own customer stories page, the company says Grok Bot, given access to vendor spend, contracts and usage data, found more than US$100,000 in direct savings for one customer. Treat that as a vendor claim, since xAI does not name the customer in the line we reviewed. Grok’s weak spot for Australian businesses is the bundling with X, which some brands will not want to put on a company card. For how Grok handles safety filters against its rivals, see our Grok vs ChatGPT vs Claude content filter test.
Perplexity: Search First, Model Second
Perplexity works differently from the other five. It is an AI search and agent platform that offers access to several third-party models, so a Perplexity subscription is partly a way to try other labs’ models behind one interface. According to its plan documentation, Perplexity’s current model table lists GPT-6.1 Sol, Gemini 4 Argon, Claude Opus 5.5, Grok 4.7, Gemini 3.8 Flash, Claude Sonnet 5.5, Kimi K3, GLM 5.3 and Nemotron 3.5 Super VL, with Gemini 4 Argon and Opus 5.5 reserved for the Max tier. Perplexity itself warns that it adds and retires models as providers change their offerings, so the list is a dated snapshot.
Perplexity’s official comparison reportedly lists Free at US$0, Pro at US$20 a month, Max at US$200, Education Pro at US$10 after student verification, and Enterprise Pro at US$40 per user per month. These figures come from a single source, so confirm them before you buy. Perplexity Computer, the agent product, became able to run fully on a Mac on 20 October 2026, with the model and files kept on the device, according to a dated report. That matters if client files cannot leave the laptop. For accuracy trade-offs against its bigger rivals, see our Perplexity vs ChatGPT vs Gemini accuracy comparison.
Benchmarks and Industry Data: What We Can and Cannot Prove
Most “best AI chatbot” articles print a leaderboard and move on. We did not, and the reason is simple. Every model in this comparison launched or updated within the past six weeks, and the sources we could verify on 23 October 2026 did not include a trustworthy, independent head-to-head score table covering GPT-6.1 Sol, Claude 5.5, Gemini 4 Argon and Grok 4.7 together. Printing a number we cannot trace would hurt you more than leaving a gap. Instead, here are the three evidence types we could verify, and what each tells a small business.
| Evidence type | Source | What it shows | Limit |
|---|---|---|---|
| Usage survey | Stack Overflow Developer Survey 2025 | Which assistants developers actually use | Developers only, and a year old |
| Analyst rankings | Gartner Magic Quadrant (28 September 2026) and Forrester Wave Q4 2026 | Microsoft named a Leader in low-code and app-generation platforms | Measures platforms, not chat quality |
| Vendor claims | Anthropic, OpenAI, Google release pages | 40% lower cost for Opus 5.5 versus Opus 5, 30%+ speed gain for Sonnet 5.5, one-fifth of Astra’s price for GPT-6.1 Sol, 95% cached-input discount for Argon | Self-reported, not independent |
What Developers Say They Use
The best independent adoption figures we can cite come from the 2025 Stack Overflow Developer Survey. Stack Overflow reported that “84% of developers reported that they use or plan to use AI tools in their development process in 2025.” On usage by assistant, the survey found ChatGPT was the most widely used out-of-the-box AI assistant among developers, followed by GitHub Copilot.
Read those figures for what they are. They describe 2025 habits of developers, before GPT-6.1 Sol, Claude 5.5 and Gemini 4 Argon existed, and the percentages overlap because people use more than one tool. They tell a small business that ChatGPT has the deepest installed base of help guides, templates and trained staff, which lowers your training cost. They do not tell you which model writes the better proposal today.
Run Your Own Ten-Prompt Benchmark
Because public scores lag the models, the most reliable benchmark for a small business is your own work. Pick ten real tasks, such as a customer complaint reply, a quote summary, a spreadsheet formula fix, a contract clause check, a social post, a meeting recap, a refund policy rewrite, a supplier email, a product description and an FAQ draft. Paste the same prompt into each chatbot on its paid entry plan. Score each answer from 1 to 5 on accuracy, tone and edit time, then add up the totals. A half-day exercise beats any leaderboard, and it will show you which tool your own staff prefer, which matters as much as raw capability.
Pricing Compared: What Six Chatbots Cost in US Dollars
All prices below come from the vendors’ own pages as of 23 October 2026 and are in US dollars. Convert at the going exchange rate and add GST where it applies. Plans that we could only confirm from a single source are described in the text above, not here.
| Plan or price point | Vendor | Price (USD) | Notes |
|---|---|---|---|
| ChatGPT Plus | OpenAI | US$20 per month | Includes GPT-6.1 Sol |
| ChatGPT Pro 100 | OpenAI | US$100 per month | No Ultrafast access |
| ChatGPT Pro 200 | OpenAI | US$200 per month | No Ultrafast access |
| ChatGPT Pro 500 | OpenAI | US$500 per month | Includes GPT-6.1 Sol Ultrafast |
| Copilot Chat | Microsoft | No extra charge | For Entra ID users on an eligible Microsoft 365 plan |
| Grok Plus (The X Subscription) | xAI | US$8 per month or US$80 per year | More Grok and Cursor usage |
| Grok Premium | xAI | US$30 per month or US$300 per year | Includes Grok Bot |
| Grok Super | xAI | US$100 per month or US$1,000 per year | Larger allowance |
| Grok Ultra | xAI | US$200 per month or US$2,000 per year | Largest allowance |
| Gemini 4 Argon API, introductory | US$2 input and US$10 output per million tokens | Until 30 November 2026 | |
| Gemini 4 Argon API, standard | US$4 input and US$20 output per million tokens | From the end of the introductory period | |
| Grok 4.7 API | xAI | US$2 input and US$6 output per million tokens | Prompts under 200,000 tokens |
To make the monthly cost concrete, here is simple arithmetic for a ten-person firm that gives every employee one seat. Ten ChatGPT Plus seats come to US$200 a month. Ten Grok Plus seats come to US$80 and ten Grok Premium seats to US$300. Copilot Chat adds nothing if your Microsoft 365 licences already qualify. Claude, Gemini and Perplexity seat prices need a live check, because we could not verify a current US dollar figure for their entry plans from the pages we reviewed.
Two cost traps are worth flagging. First, usage-based billing is spreading. Microsoft meters agents through Copilot Credits, Grok shares a usage pool between Grok Bot and its models, and OpenAI changed allowances on its Pro tier this week. A flat sticker price no longer guarantees a flat bill. Second, the Gemini API’s price doubles when the introductory period ends, so test early and budget for the higher rate.
Real-World Examples: How Businesses Use These Chatbots
Some of the examples below come from vendor announcements and are labelled that way. Others are illustrative scenarios we built from the plans and prices above. They are composites, not case studies of named Australian firms, and we have not invented any results for them.
- Spend analysis with Grok Bot (vendor claim). xAI says it gave Grok Bot access to vendor spend, contracts and usage data and that the bot found more than US$100,000 in direct savings. The lesson for a small firm is the method: point an assistant at your supplier invoices and ask it to flag duplicates and price creep.
- Hospital-scale rollout of Copilot (vendor report). Microsoft reportedly ran a trial across 90 NHS organisations in the United Kingdom. That is not evidence of Australian pricing or availability, but it shows Copilot is being tested on large, regulated workforces.
- Training an AI-ready workforce (vendor programme). Anthropic says its Claude Frontier Academy programme will train 10,000 engineers by the end of 2027, with cohorts from firms including Accenture, Deloitte and McKinsey already underway. If your accountant or consultant talks about Claude, this is why.
- Small-business marketing with Gemini (vendor announcement). Between 20 and 23 October 2026 Google promoted Gemini tools that produce product-launch and recurring-campaign materials, supported by the Nano Banana 2.1 image model. A café or retailer can draft a month of posts in an afternoon.
- Illustrative scenario: a four-person Brisbane trades business. The owner uses a ChatGPT Plus seat to turn site notes into quotes and follow-up emails. At US$20 a month the tool pays for itself if it saves one hour of admin a week.
- Illustrative scenario: a Melbourne accounting practice on Microsoft 365. Staff already hold licences that include Copilot Chat. The practice starts there, then pilots Claude Sonnet 5.5 on a separate account for long advisory letters, where careful tone matters.
- Illustrative scenario: a Perth online shop. The owner uses Gemini inside Google Workspace for product descriptions and Perplexity for competitor research with cited sources.
The pattern across all seven is the same. The wins come from narrow, repeatable tasks with a human check at the end, not from asking a chatbot to run the business. Start with one task, measure the minutes saved, and only then pay for more seats.
Use-Case Recommendations: Which Chatbot for Which Job
Here are seven common small-business jobs and our pick for each. We name a runner-up so you have a fallback if the first choice does not fit your stack.
| Use case | First choice | Runner-up | Reason |
|---|---|---|---|
| Writing emails, quotes and proposals | Claude Sonnet 5.5 | ChatGPT Plus | Anthropic pitches Sonnet 5.5 as faster and cheaper than Sonnet 5 for most work |
| Spreadsheets and Office documents | Microsoft Copilot | Gemini in Sheets | Lives inside Word, Excel and PowerPoint |
| Google Workspace teams | Gemini 4 Argon | ChatGPT | Native to the apps your team already uses |
| Research with sources | Perplexity | Gemini 4 Argon | Search-first design and source links |
| Coding and automation | ChatGPT with GPT-6.1 Sol | Claude Opus 5.5 | Both vendors target agentic coding |
| Customer support bot | Grok Bot or an API build | Claude Haiku 5.5 | Grok Bot targets support work, Haiku suits high-volume jobs at low token prices |
| Tight budget, many staff | Copilot Chat or free tiers | Grok Plus at US$8 | No added cost or lowest paid entry price |
If your needs span several rows, you do not have to choose just one. A common setup is one general assistant for everyone, plus one specialist for a single power user. Browse the full AI and machine learning section for model-by-model guides if you want to go deeper on any pick.
Migration Guide: Switching Chatbots Without Losing Your Work
Switching is easier than most owners fear, because your real assets are your prompts and your files, not the chat history. Follow this sequence over about two weeks.
- Export what you can. Use the data export option in your current chatbot’s settings and save the file in a shared folder.
- Collect your best prompts. Copy the ten prompts your team reuses most into a shared document, with one example output each.
- Run both tools in parallel for one week. Give the new chatbot the same ten tasks and compare edit time.
- Check data handling. Before you paste customer details, read the vendor’s business terms and confirm the plan you pay for covers business data. Consumer plans and business plans often differ on training and retention.
- Move accounts to a business plan. Once you commit, put the whole team on one plan with admin controls instead of a mix of personal cards.
- Retire the old subscription. Cancel only after the parallel week ends and nobody has gone back to the old tool.
If you build your own tools on top of these models, avoid locking yourself to one vendor. A routing layer lets you swap models by changing a setting, and our guide to setting up a LiteLLM multi-model router walks through that approach, although it was written for the previous generation of models, so substitute the current model names.
Pros and Cons of Each AI Chatbot
| Chatbot | Pros | Cons |
|---|---|---|
| ChatGPT (GPT-6.1 Sol) | Broadest plan ladder, strong coding and professional-work focus, large installed base of guides and trained users, up to 75% nonprofit discount on business plans | Sol is not on Free or Go, plan names and allowances change often, prices shown in USD |
| Claude (5.5 family) | Three model sizes for different budgets, Opus 5.5 priced 40% below Opus 5 on typical workloads, strong writing and coding positioning | No confirmed entry price in our sources, newest apps still in research preview |
| Gemini (4 Argon) | Fits Google Workspace, Search AI Mode access, 95% cached-input discount, fast global rollout | Argon in the app needs a paid plan, API price doubles after 30 November 2026, no confirmed AUD prices |
| Microsoft Copilot | Copilot Chat at no extra charge for eligible users, lives inside Office apps, strong analyst recognition for low-code tools | Product family is confusing, agents are metered, some billing changes exclude Australia at first |
| Grok (4.7) | Lowest paid entry at US$8 a month, large 500,000-token context window, Grok Bot for support work | Bundled with X, vendor-reported savings only, plan structure just changed |
| Perplexity | Source-first answers, access to several models, on-device Mac option for sensitive files | Top models gated to Max, model list changes without notice, not a Workspace or Office assistant |
Read the cons column as a due-diligence checklist. None of them rules a product out, but each one is a question to put to the vendor or reseller before you sign.
Verdict: Which AI Chatbot Should Your Business Pick?
Our recommendation is a stack-first rule backed by the data we could verify. Pick the chatbot that matches your productivity suite, pilot it for two weeks on ten real tasks, then add a specialist if a gap shows up.
- Microsoft 365 office: start with Copilot Chat, which costs nothing extra if your licences qualify. Add a ChatGPT Plus or Claude seat for the power user.
- Google Workspace office: start with Gemini 4 Argon on a Google AI plan. Check the Australian price at checkout.
- No fixed suite, or a mixed team: ChatGPT Plus at US$20 a month is the safest generalist, with Claude Sonnet 5.5 as the first alternative to test for writing.
- Budget under US$10 a seat: Grok Plus at US$8 is the cheapest paid ladder rung we could verify, and free tiers from OpenAI and Anthropic cover light use.
- Research-heavy work: add Perplexity for cited answers.
The honest ranking, if we must give one, is ChatGPT first for breadth, Claude second for careful writing and analysis, Gemini third for Google shops, Copilot fourth for Microsoft shops (first if you live in Office), Grok fifth for budget and social, and Perplexity sixth as a research add-on. The gaps between them are smaller than the gap between using any of them well and using none, and your own ten-prompt test will settle close calls better than any leaderboard. Revisit the decision in a few months, because Gemini’s scheduled price change and the next round of model releases are likely to land in the meantime.
Frequently Asked Questions
What is the best AI chatbot for small business in Australia?
For most small firms, ChatGPT is the best general pick, Copilot is best if you run Microsoft 365, and Gemini is best if you run Google Workspace. The right answer depends on your existing software, so test the chatbot built into your suite first.
What is the newest model from each chatbot maker?
As of 23 October 2026, OpenAI’s newest named model is GPT-6.1 Sol, Google’s is Gemini 4 Argon (generally available since 13 October 2026), Anthropic’s is the Claude 5.5 family and xAI’s is Grok 4.7. Microsoft Copilot does not name a single model, and its roadmap notes cite GPT-5.6.
How much does ChatGPT cost?
ChatGPT Plus costs US$20 a month. Pro comes in three sizes at US$100, US$200 and US$500 a month. OpenAI shows prices in US dollars, so the final Australian figure depends on exchange rates, GST and where you buy.
Is there a free AI chatbot good enough for a small business?
Yes, for light use. ChatGPT, Claude, Gemini, Grok and Perplexity all offer free access, and Copilot Chat is included at no extra charge for eligible Microsoft 365 users. Free tiers limit usage and often skip the newest model, so heavy users outgrow them quickly.
Is it safe to paste customer data into an AI chatbot?
Not without checking. Read the data-handling terms of the exact plan you use, because consumer and business plans can differ on retention and training. As a rule, keep personal customer information out of free consumer accounts and move sensitive work to a business plan with admin controls.
Does Claude, ChatGPT or Gemini give the best answers?
We could not verify an independent head-to-head score for the newest models, so we do not name a winner on answer quality. Each vendor makes its own claims, and the fairest test is ten of your own tasks run through each tool.
Will the Gemini 4 Argon API price go up?
Yes. Google’s introductory rate is US$2 per million input tokens and US$10 per million output tokens. After the introductory period expires on 30 November 2026, the public rate becomes US$4 and US$20.
Why is Meta AI not ranked?
We could not confirm a current Meta AI model, plan or price from official sources on the day of writing, and we do not rank products we cannot verify.
