Free AI Tiers Got Good: What UK Sole Traders Can Run at £0

There is a persistent myth that doing anything useful with AI means a subscription. For a sole trader running a café, a market stall or a one-person consultancy, that myth costs money you do not need to spend. The single most important development of 2026 is not a flashy new model — it is that the free tiers finally got good. The assistants now built into the software you already run will cover most of your everyday work at £0, and you can get a long way before any paid plan is worth considering.

What “Good Enough” Looks Like Now

The free offerings worth knowing about are the ones bundled into tools you may already have. Microsoft Copilot in Windows 11 and Google Gemini in Workspace between them cover most everyday use at no cost. That is the headline a busy sole trader should hold onto: the baseline is now free, capable, and sitting inside software you are likely paying for already.

For a café owner or a sole trader, “everyday use” is not abstract. It is the small, repetitive writing-and-thinking jobs that quietly eat your evenings:

• Drafting and tidying. Supplier emails, a polite reply to an awkward review, a clear notice for the door, the wording on a menu insert.
• Social posts and captions. A week of posts about the new specials board, drafted in one sitting and tweaked rather than written from scratch.
• Summarising and explaining. Pasting in a long supplier contract or a council email and asking for the plain-English version.
• Quick admin reasoning. Turning a messy list of this week’s takings into something you can hand to your accountant, or sanity-checking a rota.

None of that requires a paid plan. It requires the free assistant you can open right now.

Start at £0 — A Sole Trader’s Playbook

The point of starting free is not stinginess; it is information. Until you have used the free tier for a few weeks, you genuinely cannot tell where your actual limits are. Pay for a guess and you will probably guess wrong. Here is the sequence:

1. Use what you already have first. If you run Windows 11, Copilot is there. If you use a Gmail or Workspace account, Gemini is there. Begin with those before installing anything new.
2. Pick your two real jobs. Resist the urge to “explore AI”. Choose the two tasks you most dread — say, replying to enquiries and writing social posts — and use the free assistant for those, every time, for a fortnight.
3. Note where it falls short. Keep a scrap list of the moments it could not help: it ran out of a free limit, it could not see your own documents, it could not act inside your booking system. That list is your real spec.
4. Only then consider paying. A paid plan is justified by a specific limit you keep hitting, not by a vague sense that the paid one must be better.

Start with the free assistant inside the software you already run. Pay only when you can name the exact limit you keep hitting — not before.

When £0 Genuinely Runs Out

There is a real ceiling, and it is worth knowing where it sits so the step up is deliberate. The cheapest credible paid routes for a small business are Microsoft Copilot for Microsoft 365, at roughly $30 per user per month and requiring an existing Microsoft 365 subscription, and Google Gemini for Workspace, which is bundled into some Business Standard plans at no extra charge. The headline difference these unlock is the assistant working across your own data — your emails, your documents, your files — rather than just being a clever, isolated chat window. Roundups of the cheaper tools confirm the same shape of market: a capable free floor, then a modest paid step for deeper integration.

For most sole traders, that step is only worth taking once two things are true: the free tier is demonstrably slowing you down, and the job you want — the assistant reading your own files and inbox — is one the free version simply cannot do. If you are paying $30 a month for the privilege of letting it summarise emails you could paste in for free, you have skipped a step.

The Practical Takeaway

In 2026, a sole trader can do real, daily work with AI without spending a penny — and should. Open the assistant already built into Windows 11 or your Google account, point it at the two jobs you most dread, and run it for a fortnight. Keep a list of where it actually falls short. When that list is dominated by one recurring limit — usually the need for the assistant to work across your own emails and documents — that is your cue to look at Copilot for Microsoft 365 or bundled Gemini, and not a moment sooner. Start at £0, let the free tier tell you what you are missing, and pay only for the gap it cannot fill.
