The short answer
For most UK small businesses, the best AI tools are one general assistant (Claude or ChatGPT), a research tool you can fact-check (Perplexity), and the AI features inside software you already pay for, such as Xero for accounts and a CRM like Close. Start with one assistant, use it daily for a month, then add tools where the hours are actually going.
Affiliate note: I have an affiliate arrangement with the brands on this page, so I profit from any purchases that come from it. That said, I use every one of these tools every day to run The Oxford AI School and I vouch for their usefulness. Buying through my links costs you nothing extra, and I’ve still told you what annoys me about each one.
I run a small business that teaches other small businesses how to use AI, which means two things. I've tried a ridiculous number of AI tools. And I've cancelled most of them.
This page is the stack that survived. Every tool here earns its subscription at The Oxford AI School, either by saving me hours I can count or by bringing in work I'd otherwise miss. It's the kit behind the courses, the proposals, the books and this website. Nothing here is on the list because it has a shiny launch video.
The timing matters, too. The American Express SME Barometer this summer found UK small business owners spending around 11 hours a week on admin and finance, roughly three times longer than they spend growing the business. That's the problem these tools solve, when you use them properly. Used badly, they're a gym membership in January: paid for, admired, untouched by March.
So for each tool I've said what it's brilliant at and what it gets wrong. A recommendation without the downside is just an advert.
Key takeaways
- Pick one AI assistant first. Claude for writing and analysis, ChatGPT as the all-rounder. Both cost about £18 to £20 a month.
- Use Perplexity for research you need to defend, because every answer shows its sources.
- Switch on the AI you already own. Xero, Close, monday.com and Mailchimp all have AI built in that most owners never touch.
- The whole fourteen-tool stack costs around £210 a month at entry-level list prices. About £7 a day.
- Tools don't fix skills. A few hours of training on your own work is worth more than another subscription.
What's the best AI business software for a small business?
The best AI business software for most SMEs is the software you already run, with its AI switched on, plus one or two specialist tools for the jobs that eat the most time. Here are the ten I use to run the money, the sales, the projects, the content and the website at The Oxford AI School.

Which AI assistant is best for a small business?
For most small businesses the best AI assistant is Claude or ChatGPT, with Perplexity alongside for research and Gemini if you live in Google Workspace. I use all four every week because each one is better at different jobs. I researched and wrote my book, Learn To Fly With AI, using Claude, Perplexity and ChatGPT, and Gemini drew the illustrations, so this isn't a theoretical ranking.
| Assistant | What it's best at | How I use it | How it helps grow the business | What could be better | Price from | Link |
|---|---|---|---|---|---|---|
| Claudeby Anthropic | Writing that sounds human, long documents, careful analysis and building simple web pages. | Course outlines, proposals, blog drafts in my own voice, and pages like this one. | Proposals go out the same day, so fewer warm leads cool off while I'm busy delivering. | Usage limits on Pro bite on heavy days. No native image generation. | $20/monthFree plan available. Team from $25/seat. | Try Claude |
| ChatGPTby OpenAI | The all-rounder: images, voice mode, custom GPTs and quick everyday jobs. | Images for social posts, voice brainstorms on dog walks, and custom GPTs I build with clients. | It's the tool most delegates already use, so teaching it well wins repeat bookings. | Writes like ChatGPT unless you steer it hard. Confident even when wrong. | £20/monthFree plan available. Business from £25/user. | Try ChatGPT |
| PerplexityAI answer engine | Research with sources you can click and check. | Reading up on a prospect before a call, and fact-checking every statistic before it goes out. | I turn up to sales calls knowing the client's sector, which shortens the sales cycle. | Some sources are thin SEO blogs. Not a writer. | $20/monthFree plan available. Enterprise from $40/seat. | Try Perplexity |
| Geminiby Google | Working inside Gmail, Docs, Sheets and Drive. Deep Research for a first pass on big topics. | Summarising long email threads, pulling figures from sheets, and illustrations for the book. | Clients on Google Workspace can use AI without data leaving Google's walls, which wins over the cautious ones. | Less special outside Google's apps. Product names change faster than anyone can learn them. | £18.99/monthGoogle AI Pro. Free plan available. | Try Gemini |
Prices are list prices from each provider's own site or recent published pricing, excluding VAT where the provider shows it separately. US-billed tools are shown in dollars because that's how they charge. Prices change often, so check before you buy.
My verdict on each AI tool
The tables give you the shape. Here's the longer version, tool by tool, including who I'd steer towards it and who I'd steer away.
Is Claude the best AI for small business writing?
For writing, yes. Claude is where most of my thinking and drafting happens: course outlines, client proposals, articles and even the odd web page. It follows a brief closely and its first drafts need less sanding than anything else I've tried, which matters when your name is on the result. Projects keep each client's context in one place, so I'm not re-explaining the brief every Monday. The catch is the Pro usage limit. On a heavy build day you will hit it, usually twenty minutes before a deadline.
Best for: writing, analysis and anyone who cares how the words sound. Try Claude
Is ChatGPT worth paying for as a business?
For most teams, yes. ChatGPT is the one my delegates already have on their phones, so it's the one I teach most. It's the strongest all-rounder for images, voice conversations and quick everyday jobs, and a custom GPT is a handy way to bottle a repeatable task so the whole team does it the same way. Where it lets me down is tone. Left alone it writes like a LinkedIn post that's had too much coffee, and it will state a wrong answer with the confidence of a man at a pub quiz.
Best for: teams who want one tool that does a bit of everything. Try ChatGPT
What is Perplexity good for in a business?
Perplexity has replaced a large chunk of my Googling. Before a sales call I use it to read up on the company, its sector and anything it has said in public, and every answer comes with its sources so I can click through and check. It's also how I fact-check statistics before they go in anything with my name on it. It is not a writer, though, and the sources it picks are sometimes thin. Treat the links as the answer and the summary as a lead.
Best for: research you need to be able to defend. Try Perplexity
Should a small business use Gemini?
If you run on Google Workspace, almost certainly. So much of small business lives in Gmail, Docs and Drive, and inside those apps Gemini can summarise a long email thread, draft a reply or pull figures out of a sheet without anything leaving Google. That reassurance is often what gets a cautious client started. Its Deep Research is good for a first pass on a big subject. Outside Google's own apps it feels less special, and if you're a Microsoft 365 business, Copilot is the like-for-like choice.
Best for: businesses already running on Google Workspace. Try Gemini
Is ElevenLabs worth it for a small business?
If you make any audio or video at all, it pays for itself fast. I use it for voiceovers on course videos, explainers and social clips, and most people can't tell. The real win is speed: when one slide in a forty-minute module changes, I fix the narration that afternoon instead of re-recording the lot. The credit system takes some getting used to, retakes burn through credits quicker than you'd expect, and it sometimes needs acronyms spelled out phonetically before it says them properly. Check your commercial rights: the free plan doesn't include them.
Best for: anyone making regular audio or video without a recording budget. Try ElevenLabs
Is Xero the best accounting software for a small UK business?
For most UK small businesses, it's the one I'd pick. Xero runs the money side of the school: invoices, bank reconciliation, VAT and the reports my accountant asks for every quarter. The AI is the useful kind rather than the flashy kind. It matches bank lines and suggests codes, so the monthly tidy-up takes minutes. I've also connected Xero to Claude, which means I can ask "who owes me money and since when?" in plain English instead of building a report. The downside is price creep, with UK prices rising again in September 2026.
Best for: any UK business that wants Making Tax Digital sorted and its evenings back. Try Xero
Is Close a good CRM for a small business?
For a business that wins work through calls and follow-ups, it's excellent. Close holds every lead, conversation and proposal for our corporate training work. It's built for people who actually sell rather than people who enjoy admiring a pipeline, so calling, email sequences and reminders live in one place, and the AI summarises a lead's history before I pick up the phone. The pricing is in dollars, calls cost extra, and the best AI features sit on the Growth plan and above. If you never pick up the phone to sell, a lighter CRM may do. Sign up through my link and you get 20% off.
Best for: owner-led sales teams who call, email and follow up. Get 20% off Close
Is Granola the best AI note-taker for business meetings?
For a small business, it's the one I'd pick. Granola sits quietly on my laptop during calls and writes up the notes afterwards, without a robot "assistant" joining the meeting and making everyone sit up straighter. I jot a few words of my own while I listen, and it builds proper notes and next steps around them. That means I can actually concentrate on the client, and the proposal I send that afternoon uses their words, not my half-remembered version. It only works as well as the audio, so a dodgy line gives you dodgy notes, and it's good manners (and often the law) to tell people you're taking notes.
Best for: anyone whose sales and delivery happen on calls. Try Granola
Is monday.com good for small teams?
Yes, as long as you're disciplined about it. When a client books a team workshop there's a run of tasks from the pre-course questionnaire to the follow-up resources, and monday.com keeps them visible so nothing relies on my memory at 11pm. The AI drafts task lists and summarises boards, which takes the faff out of setup. Two gripes. Paid plans start at three seats, which stings for a very small team, and it is dangerously easy to spend a morning building a beautiful board instead of doing the work on it.
Best for: small teams running repeatable projects. Try monday.com
How does Upwork help a small business grow?
It lets you act bigger than you are. Upwork is how I bring in a video editor for a launch, a designer for a one-off graphic or a developer for a fiddly integration, without the overhead of hiring. My tip: write the brief with Claude or ChatGPT first. A tight brief is the single biggest factor in getting good work back. Quality varies wildly, screening proposals takes time, and the platform fees sit on top of the freelancer's rate, so put them in the budget from the start.
Best for: plugging skills gaps project by project. Try Upwork
Is Mailchimp still worth it for small business email?
For a list of a few thousand people, it's still the easy choice. Mailchimp handles our course announcements, event invitations and bulk sends. The AI drafting is handy for a first version, the send-time optimisation earns its keep, and the reports tell me which subject lines people actually open. The price climbs steeply as your list grows, the generative AI features sit on Standard and above, and the editor still occasionally does something baffling to a perfectly good layout.
Best for: businesses with a list they want to talk to regularly. Try Mailchimp
Is Transpond a good email marketing tool for a small business?
For a small business that wants email to work with its CRM rather than live in a separate silo, it's a strong choice. Transpond handles campaigns, automated follow-ups, sign-up forms and landing pages, and it adds SMS when an email isn't enough. The AI content assistant gets a first draft out of the way, and because it connects to Capsule CRM, contacts and tags stay in sync without exporting spreadsheets. The template library is smaller than Mailchimp's, there are fewer integrations, and the reports cover the basics rather than every metric you could want.
Best for: small businesses that want email and SMS tied to their CRM. Try Transpond
Can a small business build its own apps with Lovable?
For prototypes and internal tools, absolutely. Lovable lets you describe a tool in plain English and get a working web app back. I've used it for calculators, demo apps for workshops and testing product ideas. My first attempt was rubbish, which is exactly why I now teach people how to brief it properly. Credits vanish when it goes round in circles fixing its own bug, and anything going in front of paying customers still deserves a proper developer's eye.
Best for: testing an idea before you spend real money building it. Try Lovable
Why does a small business need Netlify?
Netlify isn't an AI tool in the chatbot sense. It's the bit that turns AI-built pages into something customers can actually visit. I've published five sites on Netlify, including TheOxfordAISchool.com, and I love it. Pages built with Claude or Lovable go live in minutes, and the free and entry plans cover most small sites. The credit-based pricing takes a minute to understand, and it assumes a little technical confidence. If the word "deploy" makes you nervous, start with a website builder and come back later.
Best for: small businesses building their own site with AI help. Try Netlify
Bought the tools. Now what?
The tools are the easy bit. The difference between a team that saves a day a week and a team that pays for fourteen subscriptions and uses two is a few hours of practical training on their own work. That's what we do. Team workshops start from £799 +VAT online, run by people who use these tools every day.
How much does an AI tool stack cost a small business?
At entry-level list prices, the full fourteen-tool stack on this page costs roughly £210 a month, or about £7 a day. That's less than a Pret lunch, for a set of tools that writes, researches, keeps the books, chases leads, plans projects, records voiceovers and builds the website.
You don't need all of it on day one. A sensible starting stack for most small businesses is one AI assistant at about £20 a month, plus switching on the AI already inside your accounting and email software. That's it. Add the rest when a specific job demands it.
The cost that actually matters isn't the subscription. It's the hours. If a £20 tool saves one person two hours a week, it has paid for itself many times over before the end of the month. If it saves nothing, it's £240 a year spent on feeling modern.
How do I choose the right AI tools for my small business?
Choose AI tools by starting with where your hours go, not with what's trending. This is the process I walk clients through, and it stops most of the wasted subscriptions before they start:-
- Write down last week's admin. Every email, quote, report and chase. For most owners it's the inbox, proposals and getting paid. That list is your shopping list.
- Pick one AI assistant and use it daily for a month. Claude or ChatGPT. Real jobs only, not toy prompts about pirate limericks.
- Switch on the AI you already pay for. Your accounting software, CRM and email platform probably have AI features sitting unused. Free wins first.
- Check the data terms before client data goes in. Use business or team plans, and read our guide on how to keep information safe using AI tools.
- Add specialist tools only for a named job. ElevenLabs because you make videos. Lovable because you need a calculator built. Never "because everyone's talking about it".
- Train the people, then measure. Hours saved per week, per person. If a tool can't show that within a quarter, cancel it.
What mistakes do small businesses make with AI tools?
The commonest mistake is buying tools before building skills. I see the same handful over and over:-
- Subscribing to everything at once. Fourteen logins, no habits, and a credit card statement that reads like a tech conference sponsor wall.
- Putting client data into free consumer accounts. Use business plans and agree some ground rules. Our guide on how to write an AI policy will get you there in an afternoon.
- Trusting the first answer. AI is a brilliant first draft and an unreliable final word. Check figures, names and anything legal.
- Vague prompts. "Write me a marketing email" gets you beige. Give it the customer, the offer, the tone and an example.
- Measuring nothing. If you can't say how many hours a tool saved last month, you can't say whether it's worth keeping.
Which AI tools are free for small businesses?
Claude, ChatGPT, Gemini and Perplexity all have free plans that are good enough to learn on, and several business tools have free tiers too. Here's what you can try today without reaching for a card:-
- Claude, ChatGPT, Gemini, Perplexity: free plans with daily or weekly limits on the best models.
- Mailchimp: free for up to 250 contacts, which is enough to test a newsletter.
- monday.com: free for up to two seats, without the AI features.
- Granola: free plan to try it on your own meetings before you pay.
- Netlify: free plan for small sites and experiments.
- Lovable: free plan with a small daily allowance of build credits.
- ElevenLabs: free credits to test, but no commercial licence, so don't publish what you make on it.
- Upwork: free to post a job. You pay when you hire.
Xero and Close don't have free plans, though both have trials and promotional pricing for new customers. Free plans are fine for learning. For daily work with client data, pay for the business plan. It's the cheapest insurance you'll ever buy.
Frequently asked questions about AI tools for small business
What is the best AI tool for a small business?
For most small businesses the best single AI tool is a general assistant: Claude if most of your work is writing, proposals and analysis, ChatGPT if you want the broadest all-rounder with images and voice. Either costs around £18 to £20 a month on the paid plan and will cover email, quotes, summaries and planning from day one.
What is the best AI business software for SMEs?
The best AI business software for an SME is usually the software you already run, with its AI features switched on. Xero for accounts, a CRM such as Close for sales, monday.com for projects and Mailchimp for email all now include AI that drafts, summarises and matches records, so check what you already pay for before buying anything new.
Is ChatGPT or Claude better for a small business?
Claude is better for writing that needs to sound like a person, long documents and careful analysis. ChatGPT is better as an all-rounder, with image generation, voice mode and the largest ecosystem of custom GPTs. Many small businesses end up using both. If you can only pick one, pick the one that suits the job you do most often.
Are free AI tools good enough for a small business?
Free plans are good enough to learn on and to test whether a tool fits. Claude, ChatGPT, Gemini and Perplexity all have free tiers, as do Mailchimp, monday.com, Netlify, Lovable and ElevenLabs. For client data and daily use, move to a paid business plan, because free plans have tighter limits and weaker data controls.
How much should a small business spend on AI tools?
Most small businesses get real value from one paid AI assistant at around £18 to £20 a user per month. The full fourteen-tool stack on this page costs roughly £210 a month at entry-level list prices, or about £7 a day. Spend more only when a specific tool is clearly saving hours you can count.
Is it safe to put business data into AI tools?
It can be, on the right plan. Business and team plans from the major AI providers state that your data is not used to train their models by default, while free consumer accounts give you less control. Agree a short AI policy, keep personal and client-confidential data out of free tools, and check each provider's data settings.
Which AI tools should a small business start with?
Start with one general assistant, used every day for a month on real work such as emails, quotes and meeting notes. Then switch on the AI features inside your accounting and CRM software. Add specialist tools like ElevenLabs or Lovable only when you have a specific job they solve.
Do I need training to get value from AI tools?
You do not need technical training, but a few hours of practical training makes a large difference. Most people who struggle with AI tools are writing vague prompts and checking nothing. A short hands-on workshop on your own work usually gets a team to a useful level within weeks rather than months.
The best AI tool is the one your team actually opens
I've watched businesses spend thousands on software that nobody logs into after the launch email, and I've watched a two-person firm get a day a week back with one £20 subscription and a morning of training. The difference was never the tool. Pick one, learn it properly, and let the rest of the stack earn its way in.
And if you'd like someone to show your team how, you know where I am. Witney, usually with a laptop and a dog that thinks it's lunchtime.
