You don't need to spend a penny to start using AI in your business. Some of the most powerful tools available offer generous free tiers that are more than enough for small businesses getting started. Here are ten we recommend to every UK SME we work with.
1. ChatGPT (Free Tier)
Best for: General writing, brainstorming, customer email drafts, research
ChatGPT's free tier gives you access to a powerful AI assistant that can draft emails, write social media posts, brainstorm ideas, summarise documents, and answer business questions. It's the Swiss Army knife of AI tools and the best starting point for most businesses.
Free tier includes: Unlimited conversations with the standard model, file uploads, and basic image generation. For a detailed comparison with other AI assistants, see our guide on ChatGPT vs Claude vs Gemini.
2. Claude (Free Tier)
Best for: Long-form writing, document analysis, proposals, detailed content
Claude excels at producing natural, well-structured written content. If you write proposals, blog posts, or client communications, Claude's free tier will noticeably improve your output quality. It's particularly good at maintaining a consistent tone of voice.
Free tier includes: Daily message allowance with the standard model, file uploads for document analysis.
3. Google Gemini (Free Tier)
Best for: Businesses using Google Workspace, data analysis, real-time research
If your business runs on Gmail, Google Docs, and Sheets, Gemini integrates directly into your existing workflow. It can summarise email threads, draft responses, analyse spreadsheet data, and pull in real-time information from the web.
Free tier includes: Access within Google Workspace, conversational AI, and image generation.
4. Canva (Free with AI Features)
Best for: Social media graphics, presentations, marketing materials
Canva's free tier now includes AI-powered design suggestions, background removal, and text-to-image generation. For small businesses that need professional-looking visuals without a designer, it's indispensable. Create social media posts, flyers, business cards, and presentations in minutes.
Free tier includes: Thousands of templates, basic AI features, and generous storage.
5. Notion AI (Free Tier)
Best for: Note-taking, project management, internal documentation
Notion combines note-taking, project management, and databases in one tool. Its AI features can summarise meeting notes, draft project briefs, generate action items from documents, and organise your internal knowledge base. The free tier is remarkably generous for small teams.
Free tier includes: Unlimited pages, limited AI queries per month, and collaboration features.
6. Tidio (Free Tier)
Best for: Website chatbots, live chat, customer support
Tidio offers a free AI chatbot that sits on your website and answers customer questions around the clock. It handles FAQs, captures leads, and hands over to you when something needs a human touch. For small businesses, the free tier covers up to 50 conversations per month — enough to see real value.
Free tier includes: Basic AI chatbot, live chat widget, and email integration.
7. Otter.ai (Free Tier)
Best for: Meeting transcription, note-taking, action item extraction
Otter joins your video calls and produces accurate transcriptions with speaker identification. After the meeting, it generates summaries and action items. No more scribbling notes during client calls or trying to remember what was agreed.
Free tier includes: 300 minutes of transcription per month and basic summary features.
8. Mailchimp (Free Tier with AI)
Best for: Email marketing, newsletters, customer campaigns
Mailchimp's free tier includes AI-powered subject line suggestions, content optimisation, and send-time optimisation. You can manage up to 500 contacts and send email campaigns with professional templates. For small businesses building their email list, it's the natural starting point.
Free tier includes: 500 contacts, 1,000 sends per month, basic AI features, and templates.
9. Make (Free Tier)
Best for: Connecting apps together, workflow automation, data syncing
Make (formerly Integromat) lets you build automated workflows between your apps without any coding. When a new booking comes in, automatically send a confirmation email, add it to your calendar, and update your spreadsheet. The free tier gives you enough to automate your most important workflow.
Free tier includes: 1,000 operations per month and access to hundreds of app integrations.
10. Grammarly (Free Tier)
Best for: Proofreading, tone adjustment, writing improvement
Grammarly catches errors, suggests improvements, and helps you adjust your tone across everything you write — emails, proposals, social media posts, and website copy. The AI-powered suggestions go well beyond basic spell-checking and help you communicate more clearly and professionally.
Free tier includes: Grammar and spelling checks, tone detection, and basic clarity suggestions.
Getting Started: The Three-Tool Stack
If ten tools feels overwhelming, start with just three: ChatGPT for general writing and thinking, Canva for visuals, and your email platform's built-in AI features. This combination covers the most ground with the least setup effort. You can add more tools as you get comfortable.
Making the Most of Free Tiers
A few tips for getting maximum value from free AI tools:
- Learn the prompts — the better your instructions, the better the output. Spend time learning how to ask for what you want.
- Create templates — save your best prompts so you can reuse them. A good prompt template saves time every day.
- Combine tools — use ChatGPT to draft content, Canva to design it, and Mailchimp to send it. Each tool handles what it does best.
- Track your usage — free tiers have limits. Know what they are so you don't hit a wall mid-project.

When to Upgrade to Paid
Free tiers are a brilliant starting point, but you'll eventually hit limits. The right time to upgrade is when:
- You're consistently hitting usage limits and it's slowing you down
- The paid features would save you more time than they cost
- You've proven the value of the tool and want to scale up
Start free, prove the value, then invest. That's the smart approach for any small business.
