Understand video with on-device AI subtitles

Haibao for Mac

Open a local video, choose the spoken and target languages, and watch with original and translated subtitles generated on your Mac.

• Local video playback: Open common video formats from your Mac, Downloads folder, or folders you choose.
• Bilingual AI subtitles: Generate speech subtitles and display the original and translated text together.
• Private by design: Local media, subtitle text, and translations are not uploaded to cloud AI services.

More than a subtitle overlay

• Your own User TV URLs: Add an authorized HTTP/HTTPS live URL, such as HLS, for live AI captions and translation. User TV is free; no channels, catalog, or playlist imports are supplied.
• Media browsing and controls: Browse recent media and Downloads, drag files into the app, use keyboard shortcuts, and adjust subtitle sources and display.
• Speech models and language packs: Choose local speech models and prepare translation language packs in Settings; performance depends on your Mac and the source.
• Common formats, not every codec: Recognizes MP4, MOV, MKV, AVI, WebM and common audio formats. Local matching SRT and network SRT/VTT subtitles depend on the source; file extensions do not guarantee codec compatibility.

Your video stays on your Mac

Core speech recognition and subtitle translation use on-device processing. Haibao does not upload your local video, file path, transcript, or translation to a cloud AI service.

• macOS 26.2 or later. Apple silicon is recommended for AI performance. Feature availability depends on version and media compatibility.

Haibao for iPhone and iPad

Bring videos in from Files or a computer on the same Wi-Fi network, then generate original and translated subtitles on your device.

• Files and Wi-Fi import: Import from the Files app or transfer large videos from a computer on the same network.
• Bilingual AI subtitles: Generate subtitles from the audio track and translate them with on-device language packs.
• No cloud AI account: Local playback and core AI subtitle processing do not require uploading your media.

Import, watch, and understand

• Your own User TV URLs: Add authorized HTTP/HTTPS live streams for real-time AI captions and translation. User TV is free; the app supplies no channel catalog, browser, or playlist import.
• Files and Wi-Fi Transfer: Import video, audio, and SRT/VTT subtitles from Files or transfer larger media from a computer on the same network.
• Subtitle controls and recent media: Choose source/target languages and subtitle size, switch sources, and return to recently played media. Local playback needs no cloud AI account.
• Native playback with fallback: AVPlayer handles native media with a VLC-based fallback for less common formats. Recognized extensions do not guarantee all codecs or embedded subtitle tracks.

Local media remains on your device
