Hi DEV! I'm Sebastian (sebklaey), and I built OpenOS Momo AI — a private, local, offline-capable PWA whose own compression AI ("Bitseed") can speak. One app, one AI, several skills: lossless compression with SHA-256-verifiable roundtrips, a chat model (a string-phase neural network, ~148M parameters, word-level, KV-cache) running entirely on-device in German and English, and a data-analysis layer that answers questions about your compressed files from real local numbers, never from guesswork.
Nothing leaves the user's device — privacy by architecture, not by promise. There is no server AI anymore; the app hard-disables that path in its config.
Why I'm posting this here
Not to ask for trust — to invite independent verification, live and reproducible:

Honest positioning
- The chat model is small (millions, not billions of parameters). App commands it handles reliably with verified building blocks; open-ended world knowledge is limited — we say so in the app settings.
- A night-training run (scheduled job, NumPy, forward+backward open in the script) is currently fine-tuning it on a German/English corpus specialized in compression and data analysis. Results are reported with perplexity on held-out data before anything is adopted.
- Blockchain signatures (Base, gasless, EIP-712) are online-only and strictly opt-in.
