Show HN: Null0 – AI Clone; Open-source CLI that gives AI your personal context
amaarc Friday, February 06, 2026
null0 stores your personal context, and the goal is to have it inject relevant context automatically into Claude, Codex, Gemini, or even OpenClaw. I built null0 because I got tired of re-explaining myself to every AI session. My preferences, my tech stack, how I think, how I write -- gone every time the context window resets.
The goal is to create an actual AI clone that predicts your intent. Imagine a future where you open your laptop and your AI Jarvis already knows what you will likely want to do based on all of the context it has.
This could act as a central data provider once users’ have used it enough, enabling hyper-personalized experiences based on your custom persona and individualistic traits. I have a big vision for this.
It's similar to OpenClaw in the sense that it's simply using your Codex, Claude Code, or Gemini API key / accounts, meaning there is no additional cost. If using Gemini, I use Cognee for the vector search. I am trying to stay away from RAG and instead switch to document header encoding.
