Hey Product Hunt! 👋 I built CapMP3 because I kept hitting the same wall: a colleague shares a cap.so recording, I just need the audio for transcription or offline listening — but there was no direct way to get it without downloading the full video and running ffmpeg manually. CapMP3 removes all that friction. Paste a cap.so or cap.link URL → get an MP3 in under 30 seconds. No install, no account required. The audio is extracted server-side, converted to 190 kbps MP3, and your browser downloads it directly. Files are deleted from our servers immediately after. A few things I'm proud of: • It actually works reliably — cap.so uses an internal API for video delivery, so I had to reverse-engineer the playlist endpoint to get clean audio tracks instead of re-encoding the full video • Privacy-first: no files stored, no tracking beyond basic analytics • 1 free download to try it — no credit card, just an email Would love your feedback — especially if you run into a cap.so URL it can't handle. Happy to fix edge cases fast. 🙏
