Upload a clip. SUBTL transcribes it with word-perfect timing, styles it beautifully, and exports a finished video — in a couple of taps.
Three taps to finished
From raw footage to a polished, captioned video — no editing experience required.
Upload your clip
Pick any vertical video from your library. No desktop, no timeline gymnastics.
Auto-caption & style
SUBTL transcribes every word with exact timing, then you pick a style and tweak.
Export to Photos
One tap renders a finished MP4 — even in the background while you keep editing.
Everything lands on the beat
Precision tools that used to need a desktop — now in your pocket.
Word-level timing
Every word is timed to the audio, so highlights and animations hit exactly when they're spoken.
Dimension
Place captions behind your subject for a premium, text-behind-person depth effect.
Per-word control
Tap any word to fix text, recolor, resize, highlight — or add a sound effect.
One-tap export
Renders a finished MP4 with live lock-screen progress — keeps going in the background.
