Drive provides a cloud-based storage solution for Google Workspace
files and other user data. Managing data in Drive can be a
time-consuming task.

Save time and effort for your users by extending Drive
with add-ons. When you build an add-on,
you can define custom interfaces that are inserted directly into
Drive, exactly where the user needs them. These interfaces help
automate Drive tasks, present additional information to the user,
or let the user interact with a third-party system without having to switch to a
new browser tab.

Add-ons can define the following kinds of extensions within
Drive:

- Non-contextual [homepages](https://developers.google.com/workspace/add-ons/concepts/homepages)
- Contextual interfaces that appear when users select items in the Drive interface.

You can't yet extend Drive using add-ons on mobile
clients.

## See what you can make

You build add-ons using
[Apps Script](https://developers.google.com/apps-script), and define their interfaces using
the Apps Script [Card service](https://developers.google.com/apps-script/reference/card-service/card-service). See [Building
add-ons](https://developers.google.com/workspace/add-ons/how-tos/building-workspace-addons) for
an overview. You configure add-on behavior using a
[manifest](https://developers.google.com/workspace/add-ons/concepts/workspace-manifests), which includes Drive-specific
sections.
