AI native

Made for agents.

Built-in tools for agents to co-author and understand your knowledge base and LLM wikis.

Agent Skills

Agents know how to navigate, edit, and grow your knowledge base out of the box.

Native MCP

Plug your knowledge base into Claude, Cursor, Codex, and other agents.

Agentic Search

Help agents find the right content with embeddings and hierarchical RAG.

Use cases

Put it to work.

Knowledge base

A living wiki for you and your team — skills, docs, notes in plain markdown, kept automatically in sync.

Engineering specs

Specs, PRDs, and roadmaps living next to the code, edited by humans and coding agents in the same loop.

Agent brain

A shared second brain your agents read from and write to — the persistent memory behind every session.

Q3 Roadmap

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.

This quarter
  • Ship the collaborative editor for docs and spaces
  • One click to share a doc, or a whole workspace
  • Git-backed sync so history and ownership stay yours
