Append -ai to Google Searches

What it does

• Automatically appends -ai to queries on Google domains (e.g. google.com, google.co.uk) when the query doesn't already include -ai.

How to use

1. Create a folder, e.g. append-ai-extension.
2. Save the three files from this gist there: manifest.json, content.js, and this README.md.
3. Open Chrome (or Edge/Brave).
4. Go to chrome://extensions.
5. Enable "Developer mode" (top-right).
6. Click "Load unpacked" and select your append-ai-extension folder.
7. Visit Google and try searches. The extension appends -ai automatically.

Notes and caveats

• This is a minimal example. Google’s UI is dynamic; if Google changes input names or DOM structure the content script might need updates.
• The extension only runs on *.google.* hosts as declared in manifest host permissions.
• The script appends the token only if it's not already present to avoid repeated appends.
• Appending -ai is implemented as adding a space + hyphen + "ai" (i.e., a search operator excluding "ai"). If you intended a different behavior (e.g., suffixing the term " -ai" vs. -ai without space), adjust the code accordingly.
• Respect user privacy: this extension operates on Google pages and modifies search queries locally. It doesn't send data elsewhere in this example.

If you want, I can:

• Make the token configurable (extension options page).
• Add support for additional search engines or customize matching rules.
• Provide a version for Firefox (minor manifest tweaks).
