## What is Undertekst?

Great subtitles on your videos – without handing your video to anyone.

Undertekst writes out the speech in your videos right on your iPhone. Fix the words on the timeline, give the text your own style and save a new video with the subtitles burned in – ready to share. Nothing is uploaded.

TRANSCRIBED ON YOUR IPHONE
• Apple's built-in speech recognition works right away
• Many languages, including English, Danish, German, French, Spanish, Japanese and Korean – and the app itself speaks the same seven
• For even higher quality, download a Whisper model in Settings
• On iOS 17 to 25, Undertekst transcribes with Whisper, a one-time download

FIX IT ON THE TIMELINE
• The video on top, the timeline below: a strip of frames, the sound wave and one block per line
• Drag a line's edges and they snap to words and pauses
• Pinch to zoom in on the timeline
• Edit words, split a line in two, merge two, or add a new one
• Undo and redo with one tap

MAKE IT YOUR STYLE
• Subtitle: text on a soft box
• Reel: big words, a few at a time
• Classic: outlined text
• Pick colours for the text and for the box or outline, and choose from five fonts
• Word by word highlights the word being said, and Pop makes words appear as they're spoken
• Let lines fade, slide or pop in
• Drag the text anywhere on the video and pinch to resize it
• Save your own styles and pick one for every new video
• A guide shows where short-video apps put their buttons, so your text doesn't end up behind them

SAVE AND SHARE
• Save to Photos or share straight away
• The whole video with subtitles, a clip of just one line, a still with its subtitle, or the original video
• The subtitles as an .srt or .vtt file, or as plain text
• Formats: Original, 9:16, 1:1, 4:5 and 16:9, with a blurred fill instead of black bars
• Your original video is never changed

YOUR VIDEO IS YOURS
The speech is transcribed and the subtitles are burned in on your phone. The video and its sound are never sent anywhere. No account, no ads, no tracking.

FREE. JUST ENJOY IT.
The whole app is free, with every feature, no ads and no subscription. If you're doing alright, you can become a supporter inside the app and get the show-off icons: extra app icons and a silly little game. Nothing gets locked, and freeloaders are still very welcome.
