📘 Product overview

The difference

It's not just a wiki. It has an agent that works with you.

The agent searches your base, reads the right documents and proposes the edits. You review and approve — nothing changes without your OK.

1

Researches

Finds the relevant documents in your wiki and understands the context before acting.

2

Proposes

Suggests the edit as a clear diff — new text, rewrite or a new document.

3

You approve

Review the proposal and apply with one click. Full control, always.
