Anthropic's AI assistant for real work, from chat to agents
Access to a range of Claude models tuned for different tradeoffs between speed, cost, and reasoning depth, including vision and long-context work.
Claude can produce working code, documents, slides, and spreadsheets in an editable side panel or output file rather than only plain chat replies.
Hand off multi-step tasks; Claude can search the web, read files, run code, and work across schedules or connectors depending on your plan.
Dedicated coding surfaces plus a developer platform and console for building applications on Claude models with API access.

Prove every user is real — invisibly and continuously.
Proof of Human runs silently behind login and checkout flows, scoring behavior in under 200 milliseconds without CAPTCHAs or friction for real people.
Continuous behavioral models look for programmatic typing, teleporting mouse movement, jump scrolling, centered clicks and pasted text to catch bots and AI agents mid-session.
The service states it collects no PII and does no cross-site tracking, helping teams meet compliance and privacy requirements.
A single script tag with a site key and user ID is enough to begin verifying sessions, and results include an example session report with explainable signals.
