I'll go first. I'm learning German, and I said "ein App" instead of "eine App" twelve times in three days. ChatGPT corrected me every single time. Every new session, it forgot we'd already been through this.
I think everyone learning a language has one of these. A mistake that survives every correction, every app, every teacher. Spanish learners mix up ser and estar for years. French learners guess genders forever. In English it's prepositions ("depends of", anyone?).
👋 Hi Product Hunt!
Quick question before the pitch: have you ever tried to learn something with
ChatGPT? A language, music theory, SQL, anything. It explains brilliantly.
Then you open a new chat and it has no idea who you are.
That was me with German after moving to Germany. Any LLM could explain any
grammar topic better than my textbook. But I kept making the same mistake
twelve times in three days, got twelve polite corrections, and no tool ever
connected the dots. Great teacher, zero memory.
So I built the system I wanted around those chats. mitDeutsch takes the
"learning with an AI chat" experience everyone already knows and adds what a
real course would have:
🧠 A persistent profile of what YOU personally get wrong, clustered by root
cause, feeding directly into what you practice next (until the pattern dies)
📚 Structure instead of endless chat: four short daily lessons (speaking with
per-word pronunciation scoring, reading, listening, writing) on topics you
actually care about. Your job, your life. Not "the pen of my aunt".
📈 Real progress you can see: streaks, error trends, CEFR level progression
📰 Daily news rewritten to your level, so you read real content from day one
📱 Web + Telegram bot, one shared profile
It's German-only for now, on purpose. Depth over breadth, and I'm learning
German myself, so I'm user number one. Free, no subscription, no card. There's
a full trial lesson on the landing page, no account needed.
One thing I'd love to hear from this community: what have you tried to learn
with ChatGPT, and where did it fall apart for you? That failure mode is
exactly what I'm building against.
