AI captions, timed word by word.
Upload a song or a video. Synctia listens, times every word, and gives you captions that follow the vocals.
How it works
1
Upload your song or video
Confirm you have the rights, then drop in an audio or video file.
2
Sign in with Google
Just once, right before we start processing — no account needed before that.
3
Download your captioned video
Watch the words appear in sync, then download the finished, watermarked video.
Built for accuracy
Word-by-word timing
Every word gets its own precise start and end time — not just line-level guesses.
No lyrics needed
Synctia listens to the audio itself. Upload a song or video and the words are written out for you.
Free to try
Upload, preview, and download a watermarked video before you ever pay for anything.
