Captora: AI Auto Captions: 52 styles, 17 languages, only audio ever leaves your phone

Hey Product Hunt! 👋 The short version, up front: your video never leaves your phone. Only the audio track is sent to our server for transcription, and it's deleted the moment it's processed. The actual rendering — the part where your footage is involved — happens entirely on-device. I'm Vladimir, and I've spent more evenings than I'd like to admit waiting for a progress bar to caption a 30-second video. That's really where Captora started. Every captioning tool I tried wanted me to upload my raw footage to someone's server, wait through a queue, and then trust a privacy policy I hadn't read. And the captions that came back usually looked like captions — generic, centered, obviously automated. So we built the version we wanted: 🔒 Video stays local, only audio goes to the server. Nothing to upload, nothing sitting in a bucket somewhere. 🎨 52 caption styles, all fully editable: fonts, colors, outlines, shadows, position, spacing. Save one as a template and every video after that is on-brand in one tap. 🌍 17 languages, with real accuracy — not just support on paper. Most captioning tools treat anything outside English, Spanish or French as an afterthought. Try feeding them Serbian, Croatian, Bosnian, Slovenian, Czech, Slovak, Polish, Hungarian, Romanian, Bulgarian or Macedonian and watch the transcription fall apart on basic words. That gap is a big part of why we built Captora in the first place. ⚡ Word-level timing, so captions land on the beat instead of dumping a full sentence at once. Captora is on both iOS and Android, and the free plan gives you 60 minutes of transcription a month with every style and language unlocked. One thing I'd love your take on: we deliberately kept the audio-only upload instead of going 100% offline, because on-device transcription models still struggle badly with the smaller languages we support — accuracy would have dropped off a cliff for half our users. Where do you personally draw that line between privacy and accuracy in the AI tools you use?
