Frequently asked questions

A video player for iPhone, iPad, Mac and Apple TV with on-device AI: it generates real-time subtitles in 20+ languages, translates speech as you watch, summarizes long videos into clickable chapter timelines, plays 100+ formats up to 8K HDR, and streams directly from Jellyfin, Plex, SMB, WebDAV and FTP.

Yes. Recognition, translation and summaries all run entirely on your device — Apple's Speech framework on iPhone, iPad and Mac, bundled Whisper CoreML models on Apple TV. Nothing is uploaded, so it all works offline.

Speech recognition in 20+ languages — Japanese, English, Chinese, Korean, Spanish, French, German and more — with translation into 25+ target languages, shown as clean dual subtitles.

iPhone and iPad (iOS/iPadOS 26+), Mac with Apple silicon (macOS 26+) and Apple TV (tvOS 18+). One download, universal purchase.

Free to download, with full format playback and a generous AI allowance (subtitles, summaries and high-res plays). A one-time PRO unlock removes the limits — no subscriptions, no recurring charges, ever.

Yes — direct connections to Jellyfin (Emby supported), Plex, and file servers over SMB, WebDAV and FTP. No intermediary servers; your credentials never leave the device.

Yes — transcripts export as standard SRT files; summaries export as Markdown or plain text.

Summaries use Apple's on-device Foundation Models (Apple Intelligence). Without it, subtitles and translation still work — summaries are skipped.
