Enable Gemini in Chrome, AI Powered History search, and DevTools AI Innovations in Google Chrome—without cleaning data or reinstalling.

Tiny Python helper that enables Chrome's built-in AI features by patching your local profile data (variations_country, variations_permanent_consistency_country, and is_glic_eligible)—no browser flags required.

• Python 3.13+ (see .python-version / pyproject.toml)
• Google Chrome installed (Stable/Canary/Dev/Beta)

1. Install uv (once):
   • Windows: powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
   • macOS & Linux: curl -LsSf https://astral.sh/uv/install.sh | sh
   • See uv installation docs for more options.
2. Install deps (creates venv automatically): uv sync.
3. Run the script: uv run main.py.
4. Chrome will close while patching; after it restarts, press Enter to finish.

1. Create and activate a venv.
2. Install deps: python -m pip install psutil.
3. Run: python main.py.

• Finds Chrome user data for Stable/Canary/Dev/Beta on Windows, macOS, and Linux.
• Kills top-level Chrome processes to avoid file locks, then brings them back.
• Sets all is_glic_eligible to true in Local State (recursive search).
• Sets variations_country to "us" in Local State.
• Sets variations_permanent_consistency_country to ["<version>", "us"] in Local State.
• Restarts any Chrome builds that were running before the patch.

• The script expects User Data/Local State to exist; if it's missing, the run can fail (launch Chrome once to generate it).
• Chrome restart only happens if the executable path can be detected from running processes.
• On macOS, process detection is name-based (Google Chrome*) and may terminate more than just the "top-level" app process.
• On Linux, process detection expects an executable name of chrome; if your build uses a different name, Chrome may not be closed (and files may remain locked).

• The script writes to your existing Chrome profile; back up User Data if you want a safety net.
• Run as the same OS user who owns the Chrome profile to ensure write access.
• Not affiliated with Google—use at your own risk.
