OpenProp Property Market AI Analyst

OpenProp is an AI property analyst for the London residential market. Ask anything in plain English — "median flat price in Lewisham 2024", "is Tower Hamlets a buyers' market", "where can a £450k budget actually reach" — and get an answer computed live from 1.76 million HM Land Registry Price Paid records (Crown copyright). No scraped portal listings, no estimates, no hallucinated postcodes. Built for buyers, renters, planning consultants, and journalists who need numbers they can defend.
