As a side-project this summer (partly to have an excuse to try out Claude Code ;D), I built a Chrome extension that hides content that doesn't match user preferences. Example usage: https://youtu.be/japjNSU3O7A

The content + preferences are sent to an LLM, which decides if the content is relevant. You can use your own OpenRouter API key, but there's also a 'free tier' which uses my key (there's a daily quota with this option, though).

The extension now also supports including images and video thumbnails in the filtering, although this is only available when using your own OpenRouter key. The code is available at: https://github.com/jac08h/great_filter

Feedback is appreciated!
