1. Your speech is transcribed
You choose the spoken language from 101. KatKut AI extracts the audio on your phone and transcribes it with a timestamp for every word.
Caption translation
Translate your video's captions into 140 languages
Speak in one language and caption in another. KatKut AI transcribes your video word by word, translates the captions into the language you choose, and burns them into a vertical video. Every line stays editable until you export, on iPhone or Android.

How it works
How caption translation works
Two settings on the setup screen: the language you speak, and the language your viewers read.
2. The captions are written in your target language
An AI model writes the captions in the caption language you picked, from any of 140. The timing stays your voice's, so each translated line appears while you are saying it.
3. You check every line
Machine translation can miss a name or an idiom. Tap any caption in the editor to rewrite it, then export. The translated captions are burned into the video.
Examples
Any spoken language to any caption language
Any of the 101 spoken languages can be the source and any of the 140 caption languages the target. A few combinations creators use:
- English to SpanishOr Spanish to English
- Japanese to EnglishOr English to Japanese, in Japanese script or romaji
- Turkish to EnglishOr English to Turkish
- Hindi to EnglishOr English to Hindi, in either script
- Arabic to EnglishOr English to Arabic
- Nepali to EnglishOr English to Nepali. Nepali subtitles
See the full list of 140 languages, including 39 caption-only languages such as Traditional Chinese, Basque, Haitian Creole, Latin and Maithili.
Script
Native script or Roman letters, on either side
When the caption language is not written in Latin letters, choose whether the captions use its own script or Roman letters. Romanising keeps the words and changes only the letters: for example, नमस्ते or namaste, こんにちは or konnichiwa. This works for captions in the spoken language too, with no translation at all.
Good to know
What to know before you translate
- One spoken language per video. Choose the main language you speak; Studio expects a single language in each video.
- Captions are burned in. The translation is part of the exported video, so it shows on every platform. There is no separate subtitle file (such as SRT) to download.
- Every caption style works. All 13 styles, including the six animated word by word, work with translated captions.
- Review before you post. The AI translates for meaning; read the captions and fix any line that does not sound like you.
FAQ
Caption translation: questions
How do I translate the captions of a video?
Open KatKut AI, tap Select 1 video and choose your video. On the setup screen, set Spoken in to the language you speak, switch on Translate captions and choose the language for the captions. Tap Generate, check the translated lines, and export.
How many languages can I translate captions into?
140. Your video can be spoken in any of 101 languages, and the captions can be written in any of 140, including 39 caption-only languages such as Traditional Chinese, Basque, Haitian Creole, Latin and Maithili.
Can I edit a translated caption?
Yes. Tap any caption on the timeline to rewrite it, drag its handles to retime it, or delete it. Every change can be undone, and nothing is rendered until you tap Export.
Is the translation burned into the video?
Yes. Translated captions are drawn into the exported 9:16 video, so they show on TikTok, Instagram, YouTube and anywhere else, including for people watching on mute. KatKut AI does not export a separate subtitle file.
What if I speak two languages in one video?
Studio expects one spoken language per video, so choose the language you speak most. If you switch languages for long stretches, the captions may need more editing, which you can do line by line in the editor.
