A net-worth tracker that counts what you own and what you know with every number traceable to its source. Conventional trackers only see bank balances, but your possessions and your earning potential are real capital that nobody measures.
Scan an item with your camera and a vision model identifies it; the value comes from real used-market comparables pulled through the eBay Browse API. Upload a resume and the app extracts a structured profile education, experience, skills, certifications then matches it against BLS labor data to estimate your market potential. Financial assets plus physical assets minus liabilities gives net worth, with market potential shown separately and never folded into the dollar figure.
The design rule we held to: AI for extraction, deterministic code for the numbers. The vision model identifies a guitar; it does not decide the guitar is worth $120. That comes from a median over real listings computed in plain C#, with the listings shown alongside the value. LLM-generated numbers can't be audited, don't reproduce, and quietly launder a guess into a fact.
