UK Government Extract Gemini planning document digitization

L2 · Supervised Verified · Demo Government / Public Sector Operations

UK i.AI built Extract with Google Gemini to digitize handwritten planning maps/docs in minutes (trials: ~3 min vs 1-2 hours), rolling out to English councils by Spring 2026 (reported by GOV.UK / Google)

Problem

~350,000 English planning applications/year rely on paper; converting historic maps/notes took planning officers 1-2 hours each (reported by GOV.UK)

Workflow

  1. Council feeds historic planning documents/maps to Extract
  2. Gemini multimodal reasoning reads text, handwriting, and map features
  3. Tools extract polygons and georeference to Ordnance Survey
  4. Structured digital data aids officers; decisions remain human

Human-in-the-loop: Planning officers retain all permission decisions; Extract digitizes and structures inputs.
