AI subtitles & offline videos.
Generate accurate AI subtitles right on your device, translate into 20+ languages privately, and keep your own videos for offline viewing. Beautiful dark player, AirPlay and Picture-in-Picture. No account required.
Your audio never leaves the phone. Transcription and translation happen on-device, so there's no upload and no account.
Transcribe any video into accurate subtitles using Apple's on-device speech engine, with a bundled fallback model on older devices. Your audio is never uploaded.
Transcribe and translate into Vietnamese, Chinese, Japanese, Korean, Spanish, French, German, and more — fully on-device with Apple's Translation engine.
Show the original and a translation side by side, translated privately on your device with no upload.
Beautiful dark-first design, clean scrubber, adjustable speed, bookmarks, read-aloud, AirPlay, Picture-in-Picture, and landscape playback.
Imported videos and generated captions stay on your device, encrypted at rest by iOS. No ads, no analytics, no account.
Save standard .srt or .vtt files, or burn subtitles into the video to share anywhere. Built for iPad with a split browsing layout.
All AI subtitle work runs locally. A per-install id restores purchases; an optional paste-link gateway and an optional bring-your-own-key cloud translation are the only network paths, and only when you use them.
