I built a file-grounded continuity system for my AI German teacher—what am I overcomplicating?

Why I built this

I use an AI named Felix as my German teacher.

Over time, I ran into a continuity problem: individual chats are fragile. Conversations become long, context can disappear, platforms change, uploaded files may become unavailable, and a fresh AI instance may not understand what happened before.

I did not want to repeatedly reconstruct my learning history, project decisions, lessons, corrections, and current state from memory.

So I began building a local, file-grounded system called DDF/Rahmenwerk.
