    Prospect screening tool

    A first pass on a prospective property, before anyone books a viewing. It pulls the free public records together, from the EPC register, Land Registry Price Paid, postcodes.io and planning.data.gov.uk, so we can see quickly whether a property is worth the proper due diligence. It doesn’t replace that: refurb costs come from a viewing, never from the tool, and anything the data can’t settle is flagged for a person to check.

    Paste a meeting transcript and get action points you can trust, pushed to Linear. An LLM proposes them, a person decides on each one, and a quote is only shown if it appears word for word in the transcript.

    Tees Valley EPC dataset
