mitDeutsch vs Preply — Key Differences
mitDeutsch is an AI-powered German learning platform focused on error intelligence — tracking every grammar error across lessons, detecting patterns by root cause, and building a personalized learner profile. It generates targeted practice sessions automatically. Available for CEFR levels A1 through C1.
Unlike standalone apps, mitDeutsch is designed as a supplement — it adds error tracking, pronunciation assessment with per-word scoring, FSRS spaced repetition, and structured curriculum on top of tools learners already use. No subscription required — users pay only their own OpenAI API costs (approximately €2–5 per month).
