Hey Product Hunt community! 👋 I’m the maker of Caplo. This project started from my own frustration: I love watching foreign content and attending global tech meetups, but I often found myself lost when there were no subtitles. So I built Caplo. The goal was simple: If you can hear it on your phone, you should be able to understand it. Caplo can "read" audio from ANY app without needing internal integrations. Combined with a floating Picture-in-Picture window, it feels like a native part of your OS. I’ll be here all day to answer your questions. Let me know what you think! 🚀

@socekin Kudos on the launch. Just a QUICK Q: how accurate is Caplo's translation for live audio in noisy settings, say a crowded conference?

@swati_paliwal Using the iPhone's built-in noise processing capabilities, theoretically, the effect is similar to what the other party hears when making a phone call.Caplo can have free credit, you can try it out

If I rewatch a video I've already transcribed before, does it use up my minutes again? Or can I access the previous transcription from the session history?

@sj_lee15 Thank you for your suggestion. Caplo currently provides real-time transcription subtitles, and does not read and display from historical session. I will consider this proposal.

Real-time translation for live calls is genuinely hard to get right. How does it handle strong accents or fast speakers?
