I made TubeSummary, a browser extension that adds a summary and Q&A button to YouTube videos. It uses your favorite OpenAI-compatible API (OpenAI, Groq, Together, etc) so you can get quick takeaways or ask the AI about the video — right below the player.

Built it because I got tired of scrubbing through endless videos just to figure out what mattered.

It's open source, I have tested on latest Chrome and Firefox.

A quick heads up for Chrome users: since I don't have a paid Google developer account, the extension isn't on the Chrome Web Store, so you'll need to install it manually. Sorry for the extra hassle! There's a step-by-step guide in the repo if you need it.
