Ask the recordAI · live city records

I research Philadelphia's property market across all 580,000+ property records — every block, house, owner, permit, school, sale, and ZIP-level trend, live at the moment you ask. Tap a question below to try me free — your first three typed questions are on the house, and unlimited research comes with membership.

About this data & fine print

Answers are generated by an AI agent querying City of Philadelphia open data at the moment you ask: OPA property assessments, Recorder of Deeds transfer records, L&I permits, violations & licenses, Dept. of Revenue tax balances, Zoning Board appeals, Police incident reports, Philly311 requests, and School District of Philadelphia catchment and school data.

City data is published as-is and can lag, contain errors, or be corrected later; school performance datasets run years behind and are labeled with their school year. AI answers can contain mistakes — verify anything that matters against the official record (property.phila.gov, atlas.phila.gov) before acting on it.
