Subtitle Fixer
Clean up machine-generated captions before you burn them in: shift or rescale the timing, stretch cues that flash by too fast to read, remove overlaps, and re-wrap long lines onto two balanced lines. Reports the fastest reading speed left so you know if it's still too quick. Runs in your browser; nothing is uploaded.
