Most small businesses don't need more AI tools. They need three or four, set up properly, doing real work.
Nearly half of UK small businesses now use AI tools, up from 22% last year, according to a Simply Business survey of 1,842 firms in August 2026. Only 19% of owners feel very confident using them. Getting hold of the tools is easy. Picking the right ones is the hard part.
Here's a stack for a small business running lean. We checked every price in September 2026. Several of these tools bill in US dollars, so the pound figures are approximate.
Layer 1: Your AI assistant
Start here. Both have useful free plans. If you hit the free limits, ChatGPT Go costs about £6 a month in the UK, and ChatGPT Plus and Claude Pro both come to around £20. Pick one and learn it properly before you add anything else.
Layer 2: Content engine
Buffer's free plan covers three social accounts with 10 scheduled posts each. Specialist writing tools like Jasper start at $59 a month billed yearly. That suits a marketing team. For most small businesses, the assistant from layer 1 handles the writing.
If your customers find you on Instagram or TikTok, I built Clutvi for this layer. It writes captions, suggests replies to comments and turns a brain dump into a month of post ideas. It costs £9.99 a month. Full disclosure: it's my product.
Short on caption ideas? Our 5 free Instagram caption templates each come with a worked example. Also ours, and free.
Layer 3: Automation
Most people skip this layer, and it's where the time savings add up. Zapier's free plan gives you 100 tasks a month, enough to test one automation. Make's Core plan costs $9 a month billed yearly, and Zapier's Pro plan starts at $19.99. Pick one job you do by hand every week, automate it, and build from there.
Layer 4: Customer service
Tidio's free plan includes 50 conversations with its Lyro AI agent, so you can see if it earns its place before you pay. The Starter plan costs $24.17 a month billed yearly.
