Agent brain
A shared knowledge base your agents read from and write to — the persistent memory behind every session.
Open source
A rich text editor and knowledge base for you and your agents.
The editor
A Notion-like editor that's just markdown under the hood.
Tables, images, code, diagrams, and more.
Drop-in apps, previews, and visualizations.
Ready-made and customizable templates.
AI native
Built-in tools for agents to co-author and understand your knowledge base.
Agents know how to navigate, edit and grow your knowledge base out of the box.
Plug your knowledge base into Claude, Cursor, Codex, and other agents.
Help agents find the right content with embeddings and hierarchical RAG.
A shared knowledge base your agents read from and write to — the persistent memory behind every session.
A living wiki for you and your team — skills, docs, notes in plain markdown, kept automatically in sync.
Specs, PRDs, and roadmaps living next to the code, edited by humans and coding agents in the same loop.
We’re bringing the whole team into one shared workspace, where people and agents edit the same files instead of losing context in a thread.
