Auto subtitles, made on your phone with no upload

Most Reels are watched with the sound off. Teleprompter Cut burns subtitles into your video that follow every spoken word. The text comes from your teleprompter script or from speech recognition, and your video stays on your phone.

How subtitles get into your video

  1. 1

    Record or load a video

    Record with the teleprompter or open an existing video from your gallery.

  2. 2

    Open the Subtitles step

    After a teleprompter take the text is already there. For a loaded video the app recognises the speech.

  3. 3

    Check the text

    Every line has its timestamp. Tap to correct it; the X removes a segment.

  4. 4

    Pick a style and render

    Choose style, size and position, then the video is rendered once with all steps.

Three ways to get the text

From the teleprompter

If you recorded with the prompter, the app knows the text and when you read each line, so nothing needs recognising. A slider shifts the timing by up to two seconds.

Android speech recognition

For loaded videos the app uses your phone's recogniser: no download, starts instantly (Android 13+, word-level timing from Android 14). If your phone has no local speech model, the device maker's service or Google processes the audio.

Whisper on the device

For higher accuracy, download a Whisper model once (57 or 182 MB). After that recognition runs offline.

Keywords in colour

Numbers and amounts are highlighted first, otherwise the most important long word, at most one per segment. Seven styles, from classic to one-word pop.

Making subtitles work

  • A few words per caption read better on a phone than whole sentences.
  • Mind the safe zones: on Reels and TikTok the buttons sit at the bottom and right.
  • One coloured number per segment is enough. If everything is highlighted, nothing stands out.

Questions

Do I have to upload my video?

No. Burning in runs on the phone and the video is not uploaded. Only the audio may go to the device maker's service or Google when Android recognition has no local speech model. With Whisper it stays on the device.

Which languages does it recognise?

The interface and subtitle translation come in 17 languages. Android recognition depends on your phone's language pack; Whisper recognises a very wide range of languages.

Can I fix mistakes in the text?

Yes. Tap any line to edit it, or remove whole segments.

Does it cost anything?

No. Subtitles, like everything in the app, are free, with no subscription and no ads.
