SottoCraft is a Windows desktop app for subtitle QC work. Unlike browser tools that upload your files or editors that cause sync drift, SottoCraft runs entirely local — no cloud, no subscription, no per-minute fees. Built-in AI transcription via Whisper, VLC-powered playback with zero seek drift, automatic audio quality flagging, spell check, character counter for broadcast compliance, foot pedal support, and export to SRT, VTT, TTML and ASS. One-time purchase.
