ChatGPT vs Claude

ChatGPT (from OpenAI) and Claude (from Anthropic) are two AI assistants that are very similar in the basics: both chat, write, summarise, analyse documents and help with coding. The differences are in the details: the style they write in, how they handle long texts, the tools that come around them and how they fit into your way of working.

What's confusing is that comparisons go stale within weeks: every few months a new model comes out and the one that was behind jumps ahead at something. That's why it's wise to distrust tables with an "outright winner" and tests done with a single question. Don't compare only prices or plans either, which change often. People tend to say ChatGPT is more of a Swiss Army knife, with lots of features in one place, and that Claude stands out with long texts and with work involving code and agents (programs that act on their own on your files or tools); check it against your own tasks.

I use both: I work mainly with Claude and still turn to OpenAI for some things. In "Why I switched from ChatGPT to Claude" I explain what made me switch, what I miss and what I still use OpenAI for, without idealising either of them. If what you're after is deciding which one to use, it'll help you more to read it with your own tasks in mind than to just go with my choice: what fits me may not fit you.
