Write, collaborate, and ship faster with AI.
An AI-first document editor with block editing, real-time collaboration, voice input, and inline comments — all in one place.
A doc editor that does more than type.
Blocks, comments, voice, and AI transforms — designed to keep the cursor moving.
AI-Powered Editing
Block-level AI transforms: rewrite, summarise, expand. The model sees your structure, not just text.
Real-Time Collaboration
Yjs CRDTs sync every keystroke. Multiplayer cursors and selection show who's editing where.
Voice Input
Dictate into any block. Transcription runs as a background worker and lands as a block you can edit.
Inline Comments
Comment on any block, resolve threads, mention teammates. Inbox surfaces what needs you.
Markdown + DOCX
Import and export to the formats your team already uses. Round-trips headings, lists, and tables.
Version History
Every save is a checkpoint. Restore any prior state or branch a doc to fork an idea.
