QRMap is indoor navigation from a QR code, built in Yaoundé, Cameroon. Hospitals, ministries, markets and trade fairs here rarely have indoor signage visitors can trust, and classic indoor navigation needs beacons, an app and weeks of mapping. QRMap only needs a QR code on a wall: the visitor scans it, the phone's browser shows the building plan, and an A* engine computes a turn-by-turn route across floors. No app, no sign-up, no hardware.

During the hackathon we added Meta's Muse Spark to remove our two biggest blockers:
1. AI guide: visitors don't know the exact name of where to go. They now ask in their own words and language . Muse Spark picks the destination, calls our route engine as a tool, and explains the real route with landmarks the visitor can see.
2. Plan reading: mapping a building took hours of manual drawing. An admin now uploads a photo or PDF of the floor plan; Muse Spark returns rooms, corridors and doors as structured JSON, shown over the photo for review.

The model reads and talks; the algorithm computes. The model never invents a path.
