Write together,
even offline
A collaborative editor that works seamlessly without internet. Y.js CRDTs resolve conflicts deterministically — every collaborator sees the same result, always.
Everything you need
Built for real teams who need their work to survive network outages.
Works offline, always
All edits go to IndexedDB first. Zero network requests block the UI. Open, edit, close — the network is optional.
Deterministic sync
Y.js CRDT (YATA algorithm) guarantees concurrent edits from multiple offline clients produce the same final state — no manual merging.
Version time-travel
Capture named snapshots at any point. Restore any version without disrupting other active collaborators.
Granular access control
Owner, Editor, and Viewer roles. Viewers are blocked at the WebSocket level from pushing any state updates.
Security-first
All sync payloads are validated with Zod. Payload size is capped at 5 MB at the transport layer to prevent OOM attacks.
AI writing assistant
Groq-powered Llama 3.3 helps you continue writing, summarize, fix grammar, or rewrite in a different tone — inside the editor.
