AUTO-ADDING SUBTITLES
Choose a video from your library. Subit transcribes audio locally and builds timed captions. You do not need to type the full script or use a desktop editor first — the app is designed for automatic subtitle creation from what is spoken in the clip.

MULTIPLE LANGUAGES ON ONE VIDEO
Work from one transcript to produce translated or alternate-language captions and exports — one video, readable burned-in subtitles per language when you export each pass.

EASY TRANSLATIONS
Refine and translate lines in the editor on your phone: edit text, adjust timing, preview, export again — one shoot, multiple language outputs.

NO ACCOUNTS, NO ADS, NO TRACKING
Open the app, pick a clip, style, export. Built for speed and privacy.
