Gmail Add-on Installation

The Fabius Gmail Add-on provides the interface to view and use AI-generated email drafts directly within Gmail. This guide covers the installation process and initial setup.

​
Prerequisites

Before installing the add-on, ensure you have:
Both the OAuth connection AND the add-on installation are required for email replies to work. The OAuth connection enables server-side processing, while the add-on provides the Gmail interface.

​
Installation Process

​
Step 1: Access the Marketplace

  1. Go directly to Fabius in Google Workspace Marketplace
  2. Note: Fabius is not yet searchable in the marketplace, so you must use this direct link

​
Step 2: Handle Beta Access

During our beta period, you may see access restrictions: If you see “Access Denied”:
  • Contact your Fabius representative to request installation access
  • Provide your Google email address
  • Installation permissions are granted on a per-user basis
If you see “Google hasn’t verified this app”:
  • This warning is expected during beta
  • Click Advanced (bottom left)
  • Click Go to Fabius (unsafe)
  • This is safe and expected behavior
