Starter Pack is free. Paid packs are one-time purchases — no subscription.

Use H0U53 with ChatGPT, Claude, Gemini, NotebookLM, or another AI tool that can read pasted or uploaded files. Founding prices may increase as new workflows and system packs are added.

H0U53 helps you organize, verify, and decide. It is not a substitute for licensed trades, permits, inspections, emergency services, or manufacturer instructions.
