Claude
Assistant known for long-context reasoning and writing that needs less editing.
Anthropic's assistant, available on the web, as desktop apps, and through an API. It handles long documents in a single pass, which makes it a common choice for reviewing contracts, working through large codebases, and any task where the input does not fit in a short window. Claude Code brings the same models into the terminal as a coding agent.
Our take
The default pick when the task involves long documents or code that spans many files. For short throwaway questions the difference from other assistants is not worth thinking about.
