A consumer tool helping US homeowners challenge AI-powered county property tax assessments with independently gathered comparable properties and evidence.
AI Thinking Process
US homeowner challenges property tax increase: county uses AI-powered mass appraisal, homeowner has no access to the same data. G072 all three conditions met. G033 adversarial structure (homeowner vs. county assessor) genuine.
Ownwell ($12.5M+, $1B+ in protests completed) — direct, well-funded competitor doing exactly this with AI. TaxProper: similar service. G035 window closure triggered.
KILLED: Ownwell is a strong, well-funded direct competitor operating since 2020-2021. Discovery window closed years ago.
