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.

The versioned filesystem built for AI agents
A 100% POSIX-compatible mount so agents and sandboxes use familiar Unix tools, with persistence, sync and version history handled transparently underneath.
Fork a workspace in milliseconds to run dozens of agents on isolated branches, then pick the best result without file locking.
Snapshot the entire filesystem at every step and restore any past state with a single API call when an agent goes off track.
Pause any agent for review, build approval queues and policy gates, then resume from the exact same workspace state.
