Is Enhancer 4 Google safe?

Clean risk

Enhancer 4 Google adds productivity features to Google Workspace apps, sending data to Google APIs using credentials the user configures.

The extension injects enhancements into NotebookLM, Google Slides, Google Apps Script, Gemini, and Google Chat/Mail. When users enable the GAS Gemini feature, the extension serializes project source code and posts it to Google's Generative Language API using the user's own API key stored in chrome.storage.sync. The Slides PDF Import feature converts PDF pages to images and sends them to a user-supplied Google Apps Script URL; the NotebookLM component overrides tab visibility properties to keep background automations running.

Where it sends data

Destinations our analysis observed Enhancer 4 Google contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
