Show HN: Turn native language audio into flashcards and shadowing practice

A language-learning tool shared on Hacker News could help learners move beyond textbooks. Lingochunk transforms native language audio into customized flashcards and shadowing exercises. The app extracts words from your recordings, identifies their base forms, and auto-groups them with contextual examples—all timestamped at the word level. Select any phrase and loop it for shadowing practice with custom gaps. An AI mode explains grammar and nuances on demand. The tool handles fifteen input languages, including experimental support for Japanese and Chinese, and exports to over thirty output languages. The creator initially built it for personal German and Greek studies and offers a free trial at lingochunk dot com.
