RemixletOverview
Browsers and AI providers
Which browsers Remixlet runs in, why it asks for access to every site, and which AI providers you can connect.
Supported browsers#
Remixlet runs in Chrome today, plus Chromium browsers that ship Chrome's built-in side panel: Microsoft Edge, Brave, Dia, and Helium. They all install from the same Chrome Web Store listing.
Remixlet lives in that side panel, so Chromium browsers without a working one are not supported. Arc is the notable one in that group.
Why the extension asks for access to every site#
So it can remix whatever page you point it at. Until you make a remixlet for a site, Remixlet does nothing there. The agent only looks at a page when you open the panel and ask it to create a remixlet for that domain.
This is one of the reasons the extension is open source. You, or a developer you trust, can read the code that runs in your browser.
AI providers#
Remixlet ships no models of its own, so you bring an AI account you already have.
| Provider | How you connect |
|---|---|
| ChatGPT | Sign in with a paid ChatGPT subscription |
| OpenAI | API key |
| Anthropic | API key |
| API key | |
| xAI | API key |
| Any OpenAI-compatible endpoint | Base URL and key: OpenRouter, Ollama, or your own local server |
Requests go straight from your browser to the provider you picked. There is no Remixlet server in between.
Where API keys live#
In your browser's extension storage, on your machine. A key never touches the pages you visit and is only ever sent to the provider it belongs to. A lint rule fails the extension's build if the background worker or the page bridge reference a key at all, or if any code puts one in a URL, a log line, or an error message.
