How to add automatic subtitles to a Reel

  1. Drop a video with speech (or an audio file for an SRT), or try the sample
  2. Choose the language and tap Recognise the words; the first time, the model downloads (about 40 MB) and stays cached
  3. Fix any word in the list and adjust the timing; choose lines or short bursts
  4. Pick a quick style, font, size, position and the highlight colour
  5. Tap Make the video with subtitles, or download the .SRT

How it works, honestly

  • On your device: the speech model (Whisper tiny, open source) runs in the browser with WebAssembly. Your video never leaves the phone.
  • Experimental: a tiny model, so names, accents and noisy clips come out wrong sometimes. English is best; Hindi, Telugu, Tamil, Spanish, French and others work, less well. Everything is editable.
  • Speed: about as long as the clip on a recent phone, faster on a laptop. Keep the page open.
  • The burned-in video keeps the original sound and size (up to 1080 px high).

Frequently asked questions

Quick answers about the auto subtitles (on-device ai) tool.

Is my video uploaded?

No. The model is downloaded once from Hugging Face and runs in your browser; the video and audio stay on your device.

Which languages?

English works best. Hindi, Telugu, Tamil, Spanish, French, German, Portuguese, Indonesian and Arabic are supported with lower accuracy; fix the words in the list.

Can I get only the text or an SRT?

Yes: Download .SRT or Copy the text. Audio files (MP3, WAV, M4A) also work for that.

It is slow or fails on my phone

Older phones with little memory may not run the model. Try a shorter clip, close other tabs, or use a laptop.
