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.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
