About Claude
Claude is Anthropic's AI assistant, built using Constitutional AI — a training approach designed to make the model helpful, harmless, and honest by default. It is notable for its long context window, which allows it to read and reason across entire documents, codebases, or research papers in a single session. Claude performs well on writing, analysis, code review, and tasks that require careful reasoning with nuance. Anthropic positions it as a safety-focused alternative to general-purpose language models, and it tends to be more deliberate in its outputs than competing assistants. Claude is available as a standalone product at claude.ai, via API, and embedded in third-party tools. The free tier is limited in usage; Claude Pro provides higher capacity and priority access. Its strongest differentiators are document-level reasoning, long-form writing quality, and its tendency to explain its reasoning rather than just producing an answer.
