Run your AI assistant fully offline: a local-first architecture

What if your AI assistant worked on an airplane? In a hospital? On a classified network? Most AI stacks fall apart without internet. They depend on OpenAI for inference, Pinecone for vectors, and half a dozen cloud APIs for everything in between. Kill the connection, kill the assistant. This article builds a complete AI assistant that works offline. Not "mostly offline." Fully offline. After initial setup, you can unplug the ethernet cable and everything still runs. The cloud dependency problem Here is a typical AI assistant stack: User query → OpenAI API (inference) ← needs internet → Pinecone/Weaviate (vectors) ← needs internet → Redis (session state) ← needs server → PostgreSQL (structured data) ← needs server Four network dependencies. Four points of failure. Four things that do not work on a plane, in a hospital server room, or inside a SCIF. The local-first stack Here is the same assistant, rebuilt to run entirely on your machine: User query → Ollama (local LLM) ← runs on your CP
