Questions
Is my video uploaded?
No. The Whisper speech model is downloaded to your browser and runs on your computer.
How do I add the subtitles to YouTube?
YouTube Studio → Subtitles → your video → Add language → Upload file → With timing, then choose the SRT.
How accurate is it?
Usually very good for clear speech. Names, jargon and heavy accents need a quick check before publishing.
Can it burn subtitles into the video?
Not yet. Upload the SRT to YouTube, or import it into your editor.
