# I Built a Local-First AI Desktop Knowledge Base — Here's What I Learned

After building docnest-ai — a hybrid RAG engine for Python — the next logical question was: what does a great end-user app built on top of it actually look like?

That question led me to build Knovex: a local-first, AI-powered desktop knowledge base that runs entirely on your machine. No cloud uploads. No subscriptions. No data leakage. Just drop in your documents, ask questions, and learn.

This post covers the architecture decisions, the problems I hit, and the interesting technical bits. If you want to skip straight to the app: tailorgunjan93.github.io/knovex
