I built the personal AI that OpenClaw should have been

The author open-sourced Nova, a self-hosted AI assistant built as a secure alternative to OpenClaw, which suffered critical security vulnerabilities including CVE-2026-25253 and the ClawHavoc supply chain attack. Nova features a unique 7-stage self-improvement pipeline where the model learns from user corrections through a two-stage detection system (regex + LLM), stores lessons in SQLite/ChromaDB with hybrid search, and generates DPO training pairs to fine-tune its own base model via Unsloth. Unlike typical RAG or prompt engineering approaches, Nova's learning loop actually updates the underlying model's knowledge.
