Users can bring existing Markdown files, folders, or ZIP archives, or create and publish a wiki through the platform’s tools. Each wiki is backed by a Git repository, allowing users to push, pull, branch, review history, and move their content elsewhere without being locked in.

The service supports rich Markdown features, including mathematical notation, syntax-highlighted code, footnotes, links between wiki pages, and embedded images. Its access controls let publishers set pages as public, private, unlisted, or shared, with visibility managed through a declarative access-control file. Users can explore and search public wikis, search private pages, follow wikis with stars, fork existing projects, and suggest edits.

wikihub also offers an API, a native MCP server, and a command-line tool for programmatic reading, searching, editing, and publishing. These options let agents and developers create accounts, manage content, and publish updates through scripts or Git workflows.
