Show HN: SimRepo – GitHub extension showing similar repositories in the sidebar

I built SimRepo, a browser extension that adds a “Similar Repositories” panel directly into GitHub repo pages (for repos with 150+ stars). It's useful for discovering related projects while browsing. It's based on a vectorized model trained on GitHub star data.

Repo: https://github.com/Mubelotix/SimRepo Chrome/Firefox support, no tracking, fully open source.

Would love feedback on the recommendation quality or UX!
