DeutschLoop is a German language tutor plugin for Claude Code and Codex that tracks a learner's recurring mistakes by root cause (a 'FehlerDNA') and uses spaced repetition (1/3/7/14/30/60 days) to resurface them until mastered. It stores progress locally as plain JSON, requires no extra API key, and adds an optional status-line companion that slots micro-review cards into the coding agent's idle time. The idea of piggybacking language practice onto AI coding workflows is an interesting and unusual combination.

Target audience: developers and language learners who use Claude Code or Codex, especially those learning German
