Google Docs, Google Sheets, and Google Slides provide a cloud-based
productivity solution with real-time collaboration. However, modifying and
surfacing relevant information in the editors is often a time-consuming task.

You can save your users time and effort by extending Docs,
Sheets, and Slides with add-ons.
add-ons for Google Forms isn't available yet.

When you build a Google Workspace add-on, you can
define custom interfaces that are
inserted directly into the Editors. These interfaces help automate 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.

With Google Workspace add-ons, you can create the following Editor interfaces:

- Homepage interfaces
- REST API interfaces
- Link preview interfaces

> [!NOTE]
> **Note:** You can't use Google Workspace add-ons for Editors on mobile clients.

## See what you can make

Google Workspace add-ons are built using the
[Card service](https://developers.google.com/apps-script/reference/card-service/card-service).
See
[Build add-ons](https://developers.google.com/workspace/add-ons/how-tos/building-workspace-addons)
for an overview.

Google Workspace add-on behavior is configured using a
[manifest](https://developers.google.com/workspace/add-ons/concepts/workspace-manifests).
To enable Google Workspace add-on for Editors, include
Editor-specific sections.

When configuring your add-on for
editors, you must decide what
interfaces to create for your add-on and what
actions it can take. See the following guides for more information:
