Hey Product Hunt 👋 I'm Sophia, the maker of Captiono.

I built it because every caption tool I tried had at least one deal-breaker: a watermark on the export, a per-minute price, or uploading my whole video to someone else's server.

What Captiono does:

Word-by-word captions in 70+ spoken languages, detected automatically
Translated subtitles in 130+ languages, still timed to the speaker (Arabic, Urdu, Persian and Hebrew laid out right to left)
50+ templates and 56 fonts, with karaoke, word-pop and highlight animations; drag captions anywhere on the frame
Export an MP4 with captions burned in, plus SRT, VTT and a transcript

What's different: your video never leaves your device. Styling and rendering happen in your browser, and only the audio is sent for transcription. Rendering keeps going even if you switch tabs.

It's free: no account, no watermark, no per-minute fees.

I'd love your honest feedback: which caption style should I add next, and which language should I improve first? 🙏
