About YouTube Nano Chapters

Generates chapters for YouTube videos that don't have them. Uses word comparison (TextTiling) on the transcript to find topic changes. You can enable Gemini Nano (Chrome's built-in local model) for better titles, but works fine without. Needs a video with an English transcript.
