SubSmith

The product is a desktop application that generates timestamped transcripts from video and audio files, provides hover dictionary lookups, and exports sentences with audio and screenshots to flashcards to support learning vocabulary from native content. It is for individual language learners who study through immersion with movies, shows, and podcasts. It is delivered as a locally processed desktop app for Linux using Whisper and FFmpeg, positioned as an alternative to browser extensions with offline processing.
