ChatGPT — the broadest ecosystem
ChatGPT has the largest set of features: image generation, data analysis, voice and custom GPTs. It's the safe default for everyday questions, drafting and general coding help, with a generous free tier.
Claude — long documents and careful writing
Claude shines on long-context work: analysing big documents, nuanced writing and coding across files. If your work involves reading or producing long, careful text, it's often the strongest of the three.
Gemini — best inside Google Workspace
If you live in Gmail, Docs and Google Search, Gemini's integration is the deciding factor. It pulls context from your Google apps and is strong at multimodal and research tasks.
How to choose
Pick ChatGPT for breadth and ecosystem, Claude for long-form writing and analysis, Gemini if you're committed to Google. All three have free tiers — try the same real task in each for a day before paying.
