ChatGPT
ChatGPT, from OpenAI, is the tool that made AI chat famous. People like it for its range. It can help with writing, planning, learning, brainstorming and many other jobs. It also has a large set of add-ons and custom assistants, which can be handy if you want to set up a repeatable routine. If you are new to AI, our ChatGPT beginner guide is a good place to start.
Claude
Claude, from Anthropic, is often praised for writing that sounds natural and for handling long documents well. If you spend your day reading reports, editing drafts or turning messy notes into clear text, many people find Claude a comfortable fit. It can also work with connected apps and files, depending on your plan.
Gemini
Gemini, from Google, is closely tied to the Google world. If you use Gmail, Google Docs, Sheets, Drive and Calendar every day, Gemini can feel like a natural extension, since it can work alongside those apps. It is also built with Google Search in mind, which can help for research.
How to choose by job
- Everyday writing and email: any of the three will do. Pick the one whose tone you like best.
- Long reports and heavy reading: try Claude and one other, and compare the summaries.
- Working inside Google apps: start with Gemini.
- Custom assistants and lots of add-ons: look at ChatGPT first.
- Research: use any tool that can search the web, and always check the sources it gives you.
Test them yourself in 15 minutes
- Pick one real task from your week, such as summarizing a long email thread or drafting a customer reply.
- Paste the same request into each tool. Use the same wording, and leave out private details.
- Score each answer on three things: is it accurate, is it clear, and does it sound like you?
- Ask each one to improve its answer once. See how well it takes feedback.
- Keep the one that needed the least editing.
Repeat with a second task, because a tool that wins at writing may not win at research. Good prompts matter more than the tool, so read our guide to writing better AI prompts before you test.
Privacy and plans
Each company has its own privacy settings and its own plans. Before you paste anything private, check the settings for chat history and for whether your chats can be used to improve the tool. Never paste passwords, bank details, or private information about other people into any of them.
Do you need more than one?
You do not have to pick a winner. Many people keep a favorite and open a second tool when the first one is stuck. A second opinion is also a good way to catch mistakes, because if two tools disagree, that is your cue to check the facts.
