Search AI Mode

About

Browser extensions for Chrome and Firefox that automatically activate AI Mode for Google, Bing, and Brave searches.

The project consists of two browser extensions (Chrome MV3 and Firefox MV2) that automatically activate AI modes for Google, Bing, and Brave searches.

Google: Appends &udm=50
Bing: Redirects /search to /copilotsearch
Brave: Redirects /search to /ask

What It Does ✅
This extension automatically:

Google Search — Appends &udm=50 parameter to every Google Search query, activating Google's AI Mode (when available in your region)
Bing Search — Redirects Bing Search queries to Bing Copilot Search (bing.com/copilotsearch) for instant AI-powered results
Brave Search — Redirects Brave Search queries to Brave Ask (search.brave.com/ask) for AI-assisted search
Toggle Control — Simple popup toggle to enable/disable the extension on demand
Persistent State — Remembers your preference across browser restarts (enabled by default)
Lightweight — Zero dependencies, minimal footprint, no data collection
What It Does NOT Do ❌
This extension explicitly does not:

Modify search results or ranking
Collect, store, or transmit your search queries
Change results for search engines other than Google, Bing, and Brave
Inject ads or promotional content
Modify any websites except search results pages
Require account creation or login
Ask for internet access beyond search engine domains
Work on search results that don't originate from the search engine (e.g., local file searches)
Modify Google Images, Google Maps, or other Google services (only Search)
Change Bing News, Bing Images, or other Bing services (only Web Search)
