Malcut - Auto Captions

Captions for a 2-minute video in 3 seconds

Every auto caption app I found was paid, so I built my own. Malcut turns the speech in your video into captions and saves the video with the captions burned in. No sign-up, no payment, no ads, no watermark.

Done in 3 seconds
On an iPhone 17, captions for a 2-minute video were ready in 3 seconds. Your video is processed right on your phone instead of being uploaded, so there is no upload to wait for. Processing time depends on your device and video.

That is why it is free
Your video, audio and captions are never sent to a server. With no server costs, every feature is free.

Just clean captions
No logo and no watermark on your video. Switch between box, outline and plain styles, and change size, color and position.

Spoken word highlight
The word being spoken lights up in yellow. Great for Shorts and Reels.

Edit captions
Fix the text and timing. Split or merge captions, and undo a delete right away.

Mixed-language captions
Choose 2–3 of 16 languages, including English, Korean and Japanese. Whisper detects the language of each speech segment and keeps captions in the original language. You can add a translated line under each caption.

Videos up to 5 minutes are supported. Supported iPhones use Apple speech recognition; otherwise a Whisper model is downloaded once. Your work is saved automatically.

On supported iPhones, choose Apple speech recognition or Whisper for multilingual captions.
