What is JAVSubs?
JAVSubs is a desktop application that generates English subtitles from Japanese video files using AI — entirely on your computer. No files are uploaded, no internet connection is needed after setup, and no accounts are required.
Drop in a Japanese video and JAVSubs will extract the audio, transcribe the Japanese speech, translate it to English, and output a timed .srt subtitle file compatible with any media player.
Key features:
- 100% local processing — your files never leave your machine
- No Python, command line, or technical setup required
- NVIDIA GPU acceleration via CUDA and Vulkan (5–10 min for a 2-hour video with 8GB+ VRAM)
- Works on CPU too (20–40 min per 2-hour video)
- Batch processing — queue multiple videos and walk away
- One-time $25 purchase, no subscription or per-video fees
- Available for Windows 10+ and Linux (Ubuntu 20.04+, Debian, Fedora)
JAVSubs is built for users who want accurate Japanese-to-English subtitles without sacrificing privacy or paying recurring fees.
