  1. 1. Choose a video

    Select a video format supported by macOS. If it contains multiple audio tracks, choose the one you want to transcribe.

  2. 2. Transcribe locally

    LegenDay generates timed subtitles from the selected audio on your Mac. Video and audio processing stay on the device.

  3. 3. Review text, timing, and style

    Correct the text, adjust each subtitle's start and end time, and preview a ready-made caption style over the video.

  4. 4. Save a new video

    Export a new MKV video with selectable subtitle tracks. The original video is never overwritten.
