How do I add captions to a video on Android with AutoCaption?
Open AutoCaption, tap Create captions and pick a video from your phone. Choose the spoken language (or leave Auto-detect) and a caption look, then tap Generate captions. The app listens to the audio, times every word, and opens the editor where you can fix words, change the style and export an MP4 or SRT.
Which languages does AutoCaption support?
About 100 spoken languages, including English, Hindi, Bengali, Marathi, Telugu, Tamil, Gujarati, Urdu, Kannada, Spanish, Arabic, Chinese, Japanese and Thai. Captions are written in the language that is spoken; the app does not translate in this version.
Does my video get uploaded?
No. The video file stays on your device. To create captions the app uploads only the audio track to the AutoCaption server, which sends it to the speech-to-text model. The audio is not stored after transcription finishes. Captions and projects stay in the app's local database.
Can I fix a word the app got wrong?
Yes. Open the Edit panel in the editor, tap the line and change the text. You can also split or merge lines, add a caption at the playhead, or delete a line. Edits save automatically and support undo and redo.
Is AutoCaption free?
The app is free to download and use. Free accounts get 2 caption minutes a day for clips up to 60 seconds, 8 templates, every font and color, SRT export, and 720p video export with a small watermark; free accounts also see ads. Pro is an in-app subscription with 300 minutes a month, clips up to 10 minutes, every template and animation, no watermark, 1080p or original-quality export, and no ads. The current price is shown in the app and billed through Google Play.
Can I export an SRT file instead of burning captions into the video?
Yes. The Export sheet has two options: Video with captions (an MP4 with the captions burned in) and Subtitle file (SRT) for YouTube, Premiere and other editors. SRT export is free on every plan.
How long can my video be?
Up to 60 seconds per clip on the free plan and up to 600 seconds (10 minutes) with Pro. Longer videos can be trimmed first in your gallery app.
Do the exported captions match the preview?
Yes. The preview in the editor and the exported MP4 use the same caption engine, so fonts, colors, animation and position match what you saw.
Caption your next video in seconds
Free to start on Android 8.0 and later. Pick a clip, get word-timed captions, make them pop, export.
