Claude

Anthropic's Claude has become the pick of developers and serious writers. Its prose sounds least like an AI, it sits atop coding benchmarks (Claude Code runs entire engineering tasks from the terminal), and its long-context handling swallows hundred-page contracts and codebases whole. Projects and Artifacts turn conversations into living documents and runnable mini-apps.

For the two things knowledge workers do most — writing and reasoning over long material — Claude's output quality is the strongest of any assistant we test, and it's the clear developer favorite.
