Features
From Persian speech to finished captions
Every step is tuned for Persian and right-to-left text.
Fully offline
All processing happens on your PC, and your video never leaves it.
Two modes: accurate and fast
Whisper large-v3 in “accurate” mode, and large-v3-turbo in “fast” mode, which is about 3× faster. Persian speech becomes word-timed text.
Smart line-splitting
Lines are split with an understanding of Persian punctuation and pauses, with correct RTL handling.
Editing with live preview
Edit lines and see the result immediately. Caption size and position are adjustable.
Three export options
An SRT file, a styled ASS file, or the video with captions burned in.
NVIDIA GPU optional
With an NVIDIA GPU it uses CUDA for speech recognition and NVENC for video export. Without one, it runs on the CPU.
Caption styles
6 styles, one click away
The previews below are simplified CSS mock-ups, not screenshots of the app.

Requirements
What you need
- Windows
- NVIDIA GPU (CUDA) optional — runs on the CPU otherwise
An NVIDIA GPU is optional. Without one it runs on the CPU, just more slowly. GPU acceleration uses a separate GPU runtime pack (about 1.2 GB) that you add only if you want it; the base installer works without it.
