Video Subtitles
SRT/VTT subtitles for videos of ANY length — 2-hour movies included. Your video never leaves your device: the browser extracts the audio locally. Pay per minute with Bitcoin.
Private by design: your video file never leaves this device. The browser extracts the audio locally and uploads only small compressed audio pieces for transcription. Works for videos of any length — no account needed.
The AI subtitle generator you pay with Bitcoin
Every other subtitle generator wants an account, a subscription, and your whole video uploaded to their cloud. This one takes none of those: the browser extracts the audio from your video locally, sends only small compressed audio pieces for AI transcription, and stitches the results into one SRT/VTT file — for a video of any length, including full movies. You pay 10 sats per minute of audio over the Bitcoin Lightning Network, with no account and no subscription.
Private by architecture, not by promise
Because subtitles only need the audio (about 1% of a video file), the video itself never leaves your device. Transcripts are deleted from our servers within 24 hours. Files with multiple audio tracks — original language, dubs, commentary — show a track picker before you pay, and an interrupted job resumes where it stopped without paying twice.
