What is Orbit

Orbit is a collaborative wiki that lives inside your Microsoft 365 tenant: a block editor for writing, real-time collaboration for teams, and portable markdown files stored in your own OneDrive and SharePoint.

Decide if Orbit fits your team

Orbit is built for teams already on Microsoft 365 who want a fast, linked wiki — meeting notes, runbooks, project docs, personal notes — without adopting a separate content silo. You sign in with your Microsoft work or school account; there is no separate Orbit account.

Three things set Orbit apart:

1. Your tenant owns the content. Every note is a portable .md file in your OneDrive or a SharePoint document library. Note bodies never enter Orbit’s database, and Orbit holds zero background (application) permissions — it acts only as the signed-in user. See Where your notes live.
2. Live collaboration. Multiple people edit the same note at once, with presence cursors, comments, and mentions. See Live editing.
3. AI access under your permissions. Claude and other MCP clients connect to your wiki through Orbit’s remote MCP connector — and can only read and write what your Microsoft account can. See Connect AI clients.

Around the core editor you get wiki links, backlinks, a graph view, full-text search, templates, drawings, and a Microsoft Teams personal tab.

Reading is free for everyone; editing takes an editor seat.
