Gemini Title Updater

README.md

Gemini Title Updater

A userscript that dynamically updates the browser tab and window title to match the active conversation in Google Gemini.

By default, the Gemini web interface does not consistently reflect the specific conversation name in the document title. This script continuously monitors the DOM for the .gds-title-m element and updates the page title to the format: [Conversation Title] | Gemini.

Use Cases

• Identifiable Tabs: Easily distinguish between multiple active Gemini conversations in your browser.
• Productivity Tracking: Enables time-tracking and productivity logging tools that rely on window titles (such as Chronoid, ActivityWatch, or RescueTime) to accurately categorize and record the specific tasks you are working on.

Installation

Add the provided .user.js file to your preferred userscript manager (Tampermonkey, Violentmonkey, etc.). The script is configured to match and run automatically on https://gemini.google.com/*.
