Features

Everything you need, nothing you don't

Fully Offline

Whisper AI runs entirely on your machine. Your files never leave your computer — no uploads, no accounts, no API keys required after the initial model download.

Batch Processing Queue

Add as many files as you need and let SRT Maker work through them automatically. Each .srt file is saved next to its source with a single click to reveal in Explorer or Finder.

Multilingual Support

Choose from Italian, German, French, English, Dutch, Spanish, Czech and Russian, or let Auto-detect figure it out. Whisper large-v3 handles accented speech and mixed audio accurately.

Three Quality Modes

Fast for quick drafts, Balanced for everyday use, and Best (Whisper large-v3) for maximum accuracy on complex or accented audio.

Drag & Drop Anywhere

Drag files directly from Explorer or Finder onto the app window. Or use the file picker. The .srt is saved right next to your original file — no extra steps.

Wide Format Support

Works with MP4, MKV, MOV, AVI, WebM, MP3, WAV, M4A, FLAC and AAC. If ffmpeg can read it, SRT Maker can transcribe it.
