How we got here
- 01
The brief
“Lean on our dashboard knowledge and public APIs as well as research — not everything has to be AI driven.” His own words.
- 02
The pattern
UK government open data is world-class — postcodes, Land Registry, Bank of England, ONS. The case-context conversation needs facts, not generated guesses. AI is the narrative wrap-up, not the source.
- 03
The move
Feed it better inputs. Live postcodes.io + three public-data fixtures (Land Registry, BoE, ONS) become the data layer. Claude only writes the closing case-context paragraph — explicitly non-advisory.
- 04
The build
Claude Haiku 4.5 (narrative only) + postcodes.io live + 3 JSON fixtures. Six-panel dashboard. ~0.3¢ per case. The AI never invents a number.
- 05
The tool
Try it below — enter a UK postcode (try SW1A 1AA), price, deposit and credit tier. Six panels populate in ~4 seconds.
Want a 'public data + light AI' build for the calls you have on the regular?
Start with DiscoverType a postcode, loan details and credit tier. The dashboard pulls live postcode data, reads structured UK market and rate data, runs the arithmetic, and asks an AI to write a non-advisory case-context summary. Not regulated advice — context for Richard to walk into a client call with.
