How "YouTube transcript" actually works here
Paste the YouTube URL, the converter downloads the video's audio, runs Whisper-class speech recognition over it, and outputs a clean text transcript. No browser extension, no manual copy-paste from YouTube's caption sidebar, no dependency on whether the video has captions in the first place. Works on any public YouTube video — uploaded captions, auto-captions, or no captions at all, all converge to the same transcript output.
YouTube auto-captions vs mdisbetter transcripts
YouTube auto-captions are flat text without paragraph breaks, often inaccurate on technical content or accented speech, and locked into the YouTube interface (you can copy from the caption sidebar but the experience is hostile). mdisbetter outputs portable text with proper paragraph breaks, runs a more accurate Whisper-class model (especially for technical terminology), and gives you a downloadable file you can paste anywhere. For the structured variant with topic-section H2s and timestamps, switch to the Markdown output.
