About Auto Captions
Make captions the way Shorts and Reels do: one word at a time, large, centered, with a strong outline. Speech is recognized in your browser (the same Whisper model as Speech to Text), you can fix any word, then burn the captions into the picture and download an MP4 plus an SRT file. No watermark and nothing is uploaded.
