Scripto v0.1.0

Local, free batch transcription & subtitle translation for macOS and Windows. Point it at a folder of videos, hit Start, walk away — transcripts (and optional translations) land next to each source file. Nothing leaves your machine.

Highlights

• Dual whisper engines, auto-selected — mlx-whisper (Apple Silicon, Metal) / faster-whisper (Windows & everything else, CPU int8 or CUDA)
• English ⇄ Chinese translation via local Ollama, extensible to more languages
• Staged pipeline that keeps the GPU busy — a 20-file batch (with translation) finishes within 4.6% of the theoretical floor, with memory flat (+0.1% across the batch)
• History with per-file language switching and in-place translation
• One-command doctor, bilingual GUI (English / 中文), dark mode, one-click model downloads
• Long recordings are chunked and re-stitched with seamless timestamps
• 137 tests; reproducible acceptance benchmarks in benchmarks/
