About

Outline is a team knowledge base and wiki focused on collaborative documents, structured collections, search, and self-hosted or cloud deployment.

Outline is a modern team wiki designed for companies that want fast collaborative documentation without the bulk of a full work-management suite. It combines Markdown-friendly editing, real-time collaboration, AI-assisted search and answers, permissions, public sharing, and self-hosted deployment options. The product is clearly in scope as a knowledge-base and workspace-doc platform rather than a disguised project manager.

Who Is Outline Best For?

Outline is particularly well-suited for:

Teams building an internal wiki

Companies wanting a lighter docs platform
