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

Overtone is a tool designed to transcribe, correct, and cut captions for various screen shapes from a single file. It excels in managing line breaks, with only 0.3% of its breaks ending on common words without a pause, significantly outperforming other methods like filling lines to the limit (28.8%) or ElevenLabs' SRT export (16.1%). Overtone also accurately identifies all speaker pauses, unlike other tools that miss a significant percentage.
