Build an AI delivery route planner for local delivery businesses, couriers, and service companies making 5 to 50 stops a day. 1. Stop import from CSV, manual entry, or copy-paste of a customer list with addresses. 2. Geocoding and address validation with correction suggestions. 3. One-day route optimization using a routing API such as Google Routes or Mapbox, which is much more reliable than writing your own solver. 4. Driver assignment and multi-vehicle splitting when one van cannot cover all stops. 5. Time windows per stop and priority flags for urgent deliveries. 6. Turn-by-turn map view and a link that opens the route in Google Maps or Waze. 7. Estimated arrival times based on real drive times, not straight-line distance. 8. Proof of delivery: photo capture, signature, and delivery notes on mobile. 9. Customer SMS notifications when the driver is en route and when delivery is complete. 10. AI-generated planning summaries: total miles, estimated hours, and warnings about tight time windows. 11. Route history and per-driver performance stats. Keep first versions to 25 stops or fewer so optimization stays fast and predictable.
