  NSW Property Insight — Chrome Web Store Listing Description
  ============================================================
  
  NSW Property Insight helps Sydney home buyers understand how competitive their budget is — using real historical settlement data from NSW Valuer General records, not estimates or agent opinions.
  
  Simply type an address, enter your budget, and click Analyze. Within seconds you receive a Market Match Index score, recent market sentiment, a suburb demand indicator, and an AI-generated plain-English summary of what the data means for your situation.
  
  ────────────────────────────────────────
  HOW IT WORKS
  ────────────────────────────────────────
  
  The Market Match Index (MMI) is a percentage score (0-100%) that estimates how your budget aligns with recent market activity for the selected location.
  
  The score is generated from multiple data inputs, including:
  
  1. Historical settlement prices
     NSW Valuer General historical residential settlement records.
  
  2. Socio-economic context (SEIFA 2021)
     ABS SEIFA suburb-level socio-economic context.
  
  3. Recent market conditions
     Publicly available suburb-level demand and clearance signals.
  
  The model uses proprietary processing steps and periodic calibration. Exact formulas, weights, and internal thresholds are not publicly disclosed.
  
  An AI-generated "Quick Read" (powered by Google Gemini) translates numerical output into plain English.
  
  ────────────────────────────────────────
