Show HN: TubeSummary – YouTube gets AI summaries in the browser
n0vella Saturday, August 02, 2025
Hey HN,
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.
Summary
TubeSummary is an open-source web extension that automatically generates concise summaries of YouTube video content, helping users quickly assess the relevance and contents of videos before watching them.
