Why Claude is the top pick
This whole library is built around it, and its writing needs the least editing afterwards.
- The best assistant for writing that sounds like you, and for working through long documents without losing the thread.
- The free plan now includes memory, connectors and Artifacts, so it's enough to test it properly. Pro at $20 a month is where the usage limits stop getting in the way.
- Fewer built-in extras than ChatGPT (it doesn't make images or video), but the core chat is the strongest here.
- The same account unlocks Claude Code, so it's the natural pick if you ever want AI to build things for you.
