Show HN: Overtone – Transcribe, correct and cut captions for any screen shape github.com

Lont released Overtone, an open-source tool that stores each spoken word once and creates caption cuts for different screen shapes, including 16:9 and 9:16. Its CLI can recut existing subtitles offline or transcribe audio with speech-recognition providers, while a video.js plugin displays the appropriate cut; the project is licensed under MIT.
