Subtitle Omid — Persian subtitling, fully offline

Subtitle Omid is a complete Persian subtitling tool that does all of its work on your own phone. No video or audio is ever uploaded, and the app needs no internet connection to work — the only one-time step is downloading the speech model.

What it does

• Choose a video from your gallery.

• The app extracts the audio and transcribes the Persian speech, word by word with timings, so every subtitle lands in the right place.

• Edit the subtitles on a timeline: change the text, adjust start and end times, split or merge cues by hand.

• Live preview: see your subtitle style on a real frame of your video before you start the final render.

Subtitles that look the way you want

Ready-made templates with previews, nine Persian typefaces, and control over size, colour, background box and position — with optional animation on the text. Every change is visible on the video frame as you make it.

Output

The finished video with the subtitles burned in and the original audio preserved, plus SRT and ASS files for editing elsewhere.

A note on privacy

All processing — audio extraction, speech recognition and video rendering — happens on the device. Nothing is sent anywhere.
