Free AI Tools for UK Small Businesses: What Each Free Tier Actually Lets You Do, and the Licensing Catches

Every free-tier limit read from the vendor's own page on 22 September 2026, who owns the output, whether your data trains the model, and how to opt out.

By The Global Insight EditorialPublished 15 min read

Free AI tiers are real and several of them will run a small business task properly, but the limit that stops you is rarely the one advertised. On 22 September 2026 we read each vendor’s own pages: Zapier’s free plan gives unlimited Zaps but only two-step ones and 100 tasks a month; Canva Free allows up to 20 Standard or Premium AI uses; Otter’s free tier gives 300 transcription minutes a month and three lifetime file imports. On the licensing question that nobody covers, both OpenAI and Anthropic assign ownership of the output to you — and both use your conversations to train their models unless you find the opt-out.

Last checked: 22 September 2026.

This page is about what you get without paying, and what the small print does to that. If you want the prices of the paid tiers instead, we read those the same way on the same day: what AI tools actually cost a UK small business. If you are still choosing between tools rather than plans, the best AI tools for UK small businesses matches one to each job.

How we checked, and what that limits

Every feature limit below was read from the named vendor’s own pricing or terms page on 22 September 2026. Nothing came from a review site, a comparison table or another article.

Why a free-tier page is more reliable than a price page. Vendors localise prices by where the request comes from. Our checks ran from a server in Germany and a browser in Bangladesh, which on the price side put four tools out of reach in our earlier cost work. Feature limits do not localise: 100 tasks a month is 100 tasks a month in Leeds or Leipzig. That is why this page can state Canva’s free-tier limits confidently while our cost page could not state Canva’s price at all.

Where a vendor would not show us a usable view, we say so rather than filling the gap. Two did on the day: Canva’s canva.com/en_gb/pricing/ served prices in Bangladeshi taka despite the UK-language URL — its free-plan feature list was still fully readable, so it is included for features and excluded for price — and Google’s AI plans page served Bangla throughout, so Gemini is in the “could not read” list below rather than in the table.

Terms and privacy pages were read in the UK/rest-of-world versions where the vendor serves one. OpenAI’s applicable terms resolved to the en-GB copy of its rest-of-world terms of use, effective 1 January 2026.

The free tiers, as each vendor states them

Tool What the free tier gives you The limit that will actually stop you
ChatGPT Free (OpenAI) Unlimited text chats, “subject to abuse guardrails” Limited messages with file uploads; limited and slower image generation; limited voice chats; limited deep research; limited memory and context
Claude Free (Anthropic) Chat on web, desktop and mobile; web search; file creation; code execution; memory across conversations; connecting apps and tools; Artifacts Anthropic points to its usage limits page rather than publishing a message count, so you cannot plan around a number
Zapier Free Unlimited Zaps, Tables and Forms; Zapier Copilot Two-step Zaps only, and 100 tasks a month. The two-step ceiling bites first
Canva Free Drag-and-drop editor and 1,000+ design types; 1.6M+ templates; 4.7M+ photos, videos, graphics and audio; ad insights and AI ad creation; access to Affinity; 5GB cloud storage Up to 20 Standard or Premium AI uses; 1 Brand Kit, 3 colours only; 5GB storage
Otter.ai Basic Zoom, Teams and Google Meet integration; live transcription; speaker identification; AI chat within and across meetings 300 transcription minutes a month; 3 lifetime audio/video file imports
Microsoft 365 Copilot Free trial on each paid plan Not a free tier. The trial ends
Google Workspace 14-day trial Not a free tier

Two things worth drawing out of that table.

“Unlimited” is doing a lot of work. Zapier’s free plan is genuinely unlimited in the count of automations you can build and strictly limited in what each one can do. A two-step Zap is trigger plus one action. The moment a process needs “when a booking comes in, add it to the sheet and send the confirmation”, you are on a paid plan. If your process genuinely is one trigger and one action, 100 tasks a month covers roughly three a day and the free plan is a real tool, not a demo.

Canva’s AI allowance is a count, not a rate. “Up to 20 Standard or Premium AI uses” is the kind of limit that never appears in a listicle, and it is the one that decides whether Canva Free is a design tool for you or a design tool with an AI demo attached.

Read from: Zapier — Plans and pricing, Canva — Pricing, Otter.ai — Pricing, Microsoft — Copilot, all read 22 September 2026.

Who owns what the AI makes, in the vendors’ own words

This is the question a small business actually needs answered before it puts AI output on an invoice, a website or a client deliverable — and it is the one the free-tools listicles skip entirely.

OpenAI, terms of use effective 1 January 2026:

“As between you and OpenAI, and to the extent permitted by applicable law, you (a) retain your ownership rights in Input and (b) own the Output. We hereby assign to you all our right, title, and interest, if any, in and to Output.”

Anthropic, consumer terms of service:

“As between you and Anthropic, and to the extent permitted by applicable law, you retain any right, title, and interest that you have in such Inputs. Subject to your compliance with our Terms, we assign to you all our right, title, and interest (if any) in Outputs.”

Note what neither says: neither assignment is limited to paid plans. On both services the free tier gets the same ownership position as the paid one.

Note also the phrase both use — “if any”. The vendors are assigning whatever rights they hold, while declining to promise that any exist. Whether AI output attracts copyright at all is a separate legal question they are carefully not answering, and one that matters if your business model depends on stopping someone else using the same output.

OpenAI is explicit about that risk in the next paragraph: “output may not be unique and other users may receive similar output from our Services. Our assignment above does not extend to other users’ output or any Third Party Output.”

The restrictions that catch small businesses out

OpenAI’s usage restrictions include three that are directly relevant to a business publishing AI-assisted work. You may not:

  • “Represent that Output was human-generated when it was not.”
  • “Automatically or programmatically extract data or Output.”
  • “Use Output to develop models that compete with OpenAI.”

The first is the one to sit with. If you are selling copywriting, reports or designs as your own human work and they are substantially AI-generated, that is a term of the service you are agreeing to, not only a question of taste.

Does your data train the model, and how to stop it

On the consumer free tiers, the default is that it does. Both vendors publish an opt-out, and both publish exceptions to the opt-out.

Anthropic: “We may use Materials to provide, maintain, and improve the Services and to develop other products and services, including training our models, unless you opt out of training through your account settings. Even if you opt out, we will use Materials for model training when: (1) you provide Feedback to us regarding any Materials, or (2) your Materials are flagged for safety review to improve our ability to detect harmful content, enforce our policies, or advance our safety research.”

OpenAI: “We may use Content to provide, maintain, develop, and improve our Services, comply with applicable law, enforce our terms and policies, and keep our Services safe.” And: “If you do not want us to use your Content to train our models, you can opt out by following the instructions” it links to.

Three practical consequences.

  1. Do the opt-out before the first sensitive paste, not after. Neither policy is retrospective in any way the terms promise.
  2. Feedback is not covered by the opt-out on Claude. Clicking a thumbs-up or thumbs-down on a response containing client detail puts that material back in scope, by the terms’ own wording.
  3. Business and enterprise tiers are usually different, which is a real reason to pay once client data is involved — but check the specific plan’s terms rather than assuming.

The UK bit: personal data in a free AI tool

Free changes nothing about your data protection obligations. If you paste a customer’s name, address, booking history or complaint into an AI tool, you are processing personal data, and UK GDPR applies exactly as it would if you had typed it into a spreadsheet.

The ICO publishes the relevant material in one place: detailed guidance on artificial intelligence and data protection, guidance on explaining decisions made with AI, and an AI and data protection risk toolkit aimed at organisations working out where their risks sit.

For a small business with no data protection officer, the version that fits on a sticky note:

  • Strip identifiers before pasting. “A customer who booked in March” works as well as their name for almost every drafting task.
  • Do not paste anything you would not email to a stranger. The training opt-out reduces the risk; it does not eliminate the transfer.
  • Never paste special category data — health, biometric, and the rest — into a consumer free tier.
  • Write down which tools you use and for what. That list is the first thing you will need if anyone ever asks.

The fuller version — special category data, when the ICO expects a DPIA, controller and processor contracts, and the rules on automated decisions — is in our guide to using AI in a UK small business, alongside eight workflows that apply it.

One more thing worth saying out loud, because it is easy to lose in a page about tools: the reason a small business owner reaches for all of this is usually workload, and workload is the single largest reported cause of work-related stress in Britain. If that is what is driving the search, managing work stress covers what the HSE framework says about it.

Which free tier covers which job

The failure mode with free AI is not choosing a bad tool. It is assuming one chat assistant covers every job, then doing three of them badly.

The job The free tier that covers it Where it stops
Drafting, rewriting, summarising, answering questions ChatGPT Free or Claude Free Uploads, images, voice and deep research are all limited on the free plans
Reading and summarising a long document Claude Free (file creation, code execution) or ChatGPT Free Message and context limits on both; Anthropic does not publish a number
Meeting notes and a searchable record of calls Otter.ai Basic 300 minutes a month; only 3 lifetime file imports, so it must capture live
Social graphics, flyers, simple video Canva Free 20 Standard or Premium AI uses; 1 Brand Kit with 3 colours; 5GB storage
Moving data between two apps automatically Zapier Free Two-step Zaps only; 100 tasks a month
Anything inside Word, Excel, Outlook or Teams Nothing free — Microsoft offers trials, not a free tier Trial ends; see our cost page for the per-seat prices
Bookkeeping with AI features built in Nothing free — Xero and FreeAgent are paid Covered on the cost page

A realistic free stack for a five-person firm is therefore one chat assistant + Canva + Otter + Zapier: four accounts, four sets of terms, four opt-out settings to check, and four ceilings to hit. That is genuinely workable, and it is also the honest argument for paying for whichever one you use most — the worked five-person example on our cost page puts numbers on what that would be.

What we could not read, and why

Stating this is part of the method rather than an apology for it.

Tool What happened on 22 September 2026 Consequence
Google Gemini / Google AI plans one.google.com/about/google-ai-plans/ served Bangla and a Bangladesh plan list No UK free-tier view we could honestly publish
Canva (prices only) Bangladeshi taka on the en_gb pricing URL Features included; price excluded
Grammarly Euro pricing served on grammarly.com/plans Free-plan features are visible but the plan comparison is priced in the wrong currency for a UK reader, so it is out

And one correction for anyone citing Google’s AI terms: the Generative AI Additional Terms of Service, still linked from many articles, carries this notice at the top: “We updated the Google Terms of Service on May 22, 2024 to cover AI-related topics. As of that date, these Generative AI Additional Terms of Service no longer apply, unless you’re a business partner with a signed agreement that references these terms.” Anything quoting that document as current Google policy is quoting a superseded page.

What the rest of this SERP gets wrong

We read the pages ranking for this query before writing. Three failures recur, and they are the reason this page exists.

Feature lists with no limits attached. Almost every list names Canva, ChatGPT and Zapier as free tools and stops there. None of the pages we read stated the two-step Zap ceiling, the 20 AI uses, or the three lifetime Otter imports — the three numbers that actually determine whether a free plan works for you.

No dates. Several pages carry 2025 or even “2026” in the title with no statement of when any of it was checked. Free tiers change more often than prices do.

Silence on ownership and training. Not one page we read told a business owner whether they own what the tool produces, whether they may sell it, or that their conversations feed model training by default. For anyone putting AI output in front of a paying client, that is the part that matters most.

A fourth, more specific to this topic: pages that present a free trial as a free tier. Microsoft 365 Copilot and Google Workspace both offer trials. A trial that ends is not a free plan, and budgeting on one is how a small business ends up with an unexpected renewal.

If you are weighing AI tools that are consumer services rather than business software, the licensing picture is different again — our explainer on why Janitor AI is so widely misunderstood covers what that category is and is not.

Frequently asked questions

Can I use AI output commercially on a free plan?

On the two we could read in full, yes, and the terms say so in plain words. OpenAI’s terms effective 1 January 2026 state that you “(a) retain your ownership rights in Input and (b) own the Output”, and that OpenAI assigns to you all its right, title and interest in Output. Anthropic’s consumer terms say “we assign to you all our right, title, and interest (if any) in Outputs”. Neither restricts that assignment to paid plans. Canva is different: its free plan includes a defined library of content whose licence terms you should read before putting a design on packaging or a paid advert.

Does my data train the model if I use a free tier?

By default, on the consumer services, yes — and both vendors publish an opt-out. Anthropic’s consumer terms say it may use your Materials “including training our models, unless you opt out of training through your account settings”, with two exceptions that apply even after opting out: feedback you submit, and material flagged for safety review. OpenAI says “If you do not want us to use your Content to train our models, you can opt out”, and links to the instructions. Find the setting before you paste anything sensitive, not after.

Is a free tier enough to run a real small business process?

For automation, the binding limit is usually structure rather than volume. Zapier’s free plan gives unlimited Zaps, Tables and Forms but only two-step Zaps and 100 tasks a month, so it is the two-step ceiling rather than the task count that normally forces an upgrade. For design, Canva Free caps you at up to 20 Standard or Premium AI uses and one Brand Kit limited to three colours. For transcription, Otter’s free tier gives 300 minutes a month and only three lifetime file imports.

What is the difference between this and just using ChatGPT free?

Mostly that no single free tier covers the jobs a small business actually has. Chat assistants handle writing, summarising and answering; they do not schedule your social posts, transcribe your meetings into a searchable archive, or move data between your booking system and your accounts. The task-to-tool table on this page maps each job to the free tier that covers it and names the limit you will hit.

Do I need to worry about UK GDPR if I paste customer details into a free AI tool?

Yes, and the free tier makes no difference to that. If you are putting personal data into a tool, you are processing it, and the ICO’s data protection obligations apply as they would anywhere else. The ICO publishes detailed guidance on AI and data protection plus an AI and data protection risk toolkit. The practical rule is simple: strip names and identifiers before pasting, and check your training opt-out first.

Why do some vendors not show a UK price or a UK view at all?

Because many localise by the country your connection appears to be in. Our checks ran from a server in Germany and a browser in Bangladesh, and Canva served Bangladeshi taka on its own en_gb URL while Google’s AI plans page served Bangla. Free-tier feature limits are the same everywhere, which is why they are on this page and the prices are not — for prices, see our separate page on what AI tools cost.

Is there anything I am not allowed to do with AI output?

OpenAI’s terms list specific restrictions that matter for small businesses publishing content: you may not “Represent that Output was human-generated when it was not”, may not “Automatically or programmatically extract data or Output”, and may not “Use Output to develop models that compete with OpenAI”. The first of those is the one most likely to catch a business out.

Should I just pay for one tool instead of stacking free ones?

Often, yes. Stacking free tiers means several accounts, several opt-out settings to check, several places your data sits, and a ceiling on each. If one job dominates your week — writing, meetings or automation — paying for that one and using free tiers around it is usually simpler than managing five free accounts.
