Cue is an open source local desktop app for creating subtitles and exporting videos with subtitles burned in. It lets you open a video, generate subtitles, edit subtitle text, style subtitles including karaoke-style word highlighting, preview the result on the video, and export the final burned-in video. It runs locally rather than uploading media to a web service. The stack is Tauri + React for the desktop app, Python for the backend, and FFmpeg plus Whisper-based transcription for processing. Feedback on the subtitle editing workflow, styling and preview controls, and export reliability would be useful.
