TIL the difference between closed captions and subtitles! While this little project currently leans more toward closed captions, the goal is to eventually support subtitles as well.
I’ve been playing around with LLMs for a while, but hadn’t built anything useful—until now.
I love watching YouTube videos that don’t have captions or subtitles, and with the recent Gemini 2.5 Pro experimental release (which can access full video content), I figured… why not make a browser extension to generate them?
So I did.
I used a mix of ChatGPT, Claude, and Gemini to build it—and honestly, they wrote around 80% of the code. It’s wild how much faster it is to ship something useful now compared to when I built my first extension (which took me days).
The extension is still in its early stages, but it works. You’ll need to bring your own API key. Feedback is very welcome, and I’ll keep improving it!
