About this extension

Create custom userscripts for any website using AI. Fix bugs, add features, and customize pages with LLM assistance.

Read the publisher’s full description

Live-edit websites with AI assistance to work around site limitations, add custom buttons, customize appearance, and speed up workflows. Bring your own OpenAI API key! To get started click the extension icon in the menubar, and then the gear icon in the sidebar once it opens. After that you can navigate to any site you want to customize, open the sidebar, click + New Mod at the top. 1. Start by choosing regions of the page to customize (powered by react-grab) 2. Chat with the LLM to describe the changes you want it to make to the page 3. The LLM will generate a userscript mod and the page will auto-refresh to apply it 4. Iterate to ask for tweaks or changes if necessary, the LLM gets a fresh screenshot + html each time 5. Hit save once you're done! After that, your custom mod will apply every time you visit that page. You can manage the list of active mods for each domain in the sidebar, and failing mods will be auto-marked with a red status icon, making AI-assisted maintenance over time easy. Extension also includes support for importing and modifying existing user scripts from popular repos like Greasyfork and OpenUserJS.org. After importing an existing script, you can further customize it using the same LLM chat interface.
