📘 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 already written changes without your OK.

1

Researches

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

2

Proposes

Writes new documents and suggests changes to existing ones, showing what goes in and what comes out.

3

You approve

A change to an existing document only goes in if you approve it — and every version stays in the history.

Everything it does

One place to document, collaborate and let AI work with you.

✍️

Block editor

Tables, task lists, callouts, code, embeds and Mermaid diagrams — with slash commands.

🧠

Multi-provider AI

OpenAI, Google Gemini, OpenRouter, LiteLLM or local models (Ollama). Never locked to one vendor.

🗺️

Mind map

In board mode, the AI draws a mind map of the document so you see knowledge in a new way.

💬

Comments & versions

Discuss passages and see what changed between an older version and the text as it is now.

🔌

Embeds & integrations

Embed videos, sheets, Figma, links and more — right in the document.

🎨

Per-company theme

Your own logo, primary color and font — a wiki that looks like your brand.
