AI Analysis

●●SolidSolve My ProblemNiche Gem

Solves a real accessibility gap Google Maps ignores, but early-stage geographic coverage limits reach.

Strengths
  • •Problem is genuine and badly solved elsewhere—Google Maps truly is yes/no checkbox useless
  • •Trust-weighted community verification + OSM data cross-reference is thoughtful approach to data quality
  • •Free API tier + offline map caching shows builder understands actual user constraints
Weaknesses
  • •Coverage limited to 6 states; forces choice between comprehensiveness and depth
  • •No clear moat vs building same dataset in any other geography—relies on first-mover advantage

Post Description

Solo dev, Hudson Valley NY. I built ROLLIN because Google Maps gives wheelchair users a yes/no checkbox and calls it accessibility data.

ROLLIN scores locations 0-100 across 6 features: wheelchair entry, accessible restroom, level entry, parking, wide aisles, elevator. Data pipeline pulls from OpenStreetMap, cross-references Google Places, and layers in community verification with a trust-weighted scoring system.

Stack: Vanilla JS (no frameworks), Netlify serverless, Supabase/Postgres, Leaflet maps. ~56K locations across NY, CA, FL, MA, NJ, PA.

Free to use, free API tier for developers. Paid tiers for higher volume and commercial use.

Ill be happy to answer any questions. :)
