What "99% accurate" actually means
On clean audio — a single clear speaker, minimal background noise — modern speech recognition gets nearly every word right, so the transcript arrives at up to 99% accuracy and your review pass takes seconds. Accuracy drops with heavy background music, overlapping speakers, or thick reverb, which is exactly why every generated line stays editable: the AI does the transcription and the timing, and you only polish the handful of words it missed.
Timing is the half of subtitling most tools get wrong and most people underestimate. watchFIWN syncs each caption to the actual speech, breaks lines where a reader would naturally pause, and keeps captions short enough to read at Reels speed — so the output is usable as-is, not a wall of text you have to re-cut by hand.

Frequently asked questions
Is the auto-subtitle generator really free?
Yes — the Free plan includes starter transcription minutes with no card required. Paid plans add more hours, watermark-free exports, and the full set of caption animations.
How is 99% accuracy possible?
On clear speech with good audio, modern AI transcription misses very few words. The last 1% — unusual names, brand terms, heavy slang — is why the editor lets you fix any line before export.
How long does it take?
Transcription usually finishes in a fraction of the video length — a 10-minute video is typically captioned in a couple of minutes.
Can I export subtitles without the video?
Yes. Download the captions alone as SRT or VTT and upload them to YouTube, Vimeo, or any player that accepts subtitle files.
Does it work for Reels and Shorts?
Yes — vertical video is fully supported, and the caption presets are sized for phone screens, so burned-in subtitles stay readable at Reels speed.
