You don't need to understand how AI works to use it. The tools on this list are designed for everyday people — they have clean, simple interfaces, free tiers that are genuinely usable, and they work for common real-life tasks without any technical setup. This guide focuses on what each tool is actually good for, so you can pick the right one for the job.
ChatGPT — the one most people start with
Website: chat.openai.com | Free tier: Yes
ChatGPT is the most widely used AI tool and a solid first choice. You type a message, it responds. That's genuinely it. The interface is clean — it looks like a messaging app. You can ask it to write something, explain something, help you plan something, or just answer a question.
Best for: writing, planning, research, brainstorming, explaining concepts
Free tier: The free plan (GPT-3.5) handles most everyday tasks well. GPT-4o (paid) is more capable for complex tasks, but the free version is a reasonable starting point.
💡 Good first prompt to try
"I have a week-long holiday in Rome coming up. Can you give me a simple 5-day itinerary for someone who wants to see the main sights but also explore some local neighbourhoods? I enjoy food and architecture."
Claude — thoughtful conversations and long documents
Website: claude.ai | Free tier: Yes
Claude is made by Anthropic and is one of the most capable AI assistants available. Many users find its responses feel more natural and considered than other tools. It's particularly good for working with longer pieces of text — paste in a document, a contract, or a long email thread and ask it to summarise, analyse, or help you respond.
Best for: analysing long documents, natural-sounding writing, sensitive or nuanced topics
Google Gemini — built into Google's tools
Website: gemini.google.com | Free tier: Yes
Gemini is Google's AI assistant and works seamlessly with Gmail, Google Docs, and Google Drive. If you already use Google's tools, Gemini is the lowest-friction option — it's right there when you're writing an email or working in a document.
Best for: Gmail users, Google Workspace, quick web searches with AI summaries
Grammarly — writing improvement that works in the background
Website: grammarly.com | Free tier: Yes
Grammarly installs as a browser extension and then checks your writing wherever you type — in Gmail, in forms, in documents, in social media posts. You don't have to do anything differently. It underlines potential issues and offers suggestions. The free version covers grammar and spelling; paid adds tone suggestions and clarity improvements.
Best for: anyone who wants ongoing writing improvements without changing their workflow
Perplexity — search with sources
Website: perplexity.ai | Free tier: Yes
Perplexity works like a search engine combined with an AI summariser. You ask a question and get an answer, but — unlike most AI tools — it shows you the sources it used. This makes it much more trustworthy for research, because you can click through and verify the information yourself.
Best for: research questions where you want to see the evidence, staying up to date with recent events
Otter.ai — automatic meeting and lecture transcription
Website: otter.ai | Free tier: Yes (limited hours)
Otter records audio — from a meeting, a lecture, an interview, or a call — and automatically produces a written transcript. It identifies different speakers and makes the transcript searchable. Students use it for lectures; professionals use it for meetings so they can be present rather than taking notes.
Best for: anyone who regularly needs to capture spoken information in written form
How to choose
If you've never used an AI tool before, start with ChatGPT or Claude. Both are free to use without an account (though Claude requires a free sign-up). Try one of them for a week with specific tasks in mind — writing an email, planning something, getting an explanation — and see how it fits into your routine.
Add other tools only when you have a specific need they address: Grammarly if you want ongoing writing support, Otter if you need transcriptions, Perplexity if you want sourced research.
✅ Quick tip
You don't need a paid subscription to get real value from any of these tools. Start with the free tier, use it consistently for a few weeks, and only upgrade if you find yourself hitting the limits regularly.
