## What is Tweeks?

Tweeks is a browser extension for Chromium (Chrome, Edge, Brave, etc.) and Firefox that lets anyone modify how websites look and behave. Users describe what they want to change in plain English, and an AI model generates a small script (called a "tweek") that modifies the page. Changes persist across page reloads and browser sessions without any configuration.

Tweeks is fully compatible with Greasemonkey-style userscripts, making it a drop-in alternative to Tampermonkey and Greasemonkey. Unlike those tools, Tweeks does not require users to write code. The extension uses a three-world security model: MAIN world (script execution), ISOLATED world (security bridge), and a Service Worker (orchestration).

## Key Differences from Tampermonkey / Greasemonkey

- Tweeks: AI generates scripts from natural language descriptions; no coding required
- Tampermonkey / Greasemonkey: Require users to write or paste JavaScript manually
- Tweeks makes sharing easy and includes a public library of 4,000+ community scripts installable with one click
- Tweeks can be used for free
