These three assistants dominate the AI world, and most people only need one. Here's how they compare on the things that actually matter — so you can pick without paying for all three.
Writing and reasoning
Claude tends to lead on long-form writing, nuanced tone and careful reasoning, making it a favourite for anyone who writes or analyses for a living. ChatGPT is a superb all-rounder with the widest ecosystem. Gemini is close behind and improving fast.
Coding
Claude and ChatGPT are both excellent for coding, with Claude often preferred for larger codebases thanks to its big context window. Gemini is strong too and integrates neatly with Google's developer tools.
Research and up-to-date facts
Gemini has a natural edge here through its tie-in with Google Search, while ChatGPT and Claude both browse the web well. For source-cited research, many people add Perplexity alongside whichever assistant they choose.
Value for money
All three offer a capable free tier and a roughly $20/month paid plan. The free tiers are genuinely good — start there, and only upgrade once you hit limits on the specific tasks you care about.
The verdict
For writing and analysis, Claude. For an everyday all-rounder with the biggest ecosystem, ChatGPT. For deep Google integration and multimodal tasks, Gemini. You can't go badly wrong — try the free versions on your own real tasks and trust what feels best.
