# Documentation

Guides to the platform's tools, for the people who use them and the IT teams who set them up. Each organisation sees these tools under its own name.

## Office Assistant

An add-in for Excel and Word that puts your organisation's AI assistant beside the open file. It reads and changes only that file, only when asked, and shows each change before it's made.

- [Overview](/office-assistant/): what it is, what it can touch and what it needs, at a glance.
- [For Microsoft 365 administrators](/office-assistant/admin/): requirements, uploading the add-in and assigning users, sign-in, where data goes, and removal.
- [Using the Office Assistant](/office-assistant/guide/): opening it, the right-click menu, keyboard shortcuts, approving and undoing changes, and what it can't do.
