Claude
A long-context assistant that writes like a careful editor, not a chatbot.
Writing & Research
A long-context assistant that writes like a careful editor, not a chatbot.
Open product
Claude is built around long documents and sustained reasoning: drop in a 200-page contract, a codebase or a research folder and ask for a structured read. Artifacts render working code, diagrams and documents side by side with the conversation.
Projects keep reference material attached across sessions, and the desktop app can read local files and drive a browser. Anthropic positions it for teams that care about instruction-following and refusal quality.
