  • Dashboard KPIs, calendar, downloadable revenue & retention reports
  • Driver applications funnel, drivers, vehicles, document expiry alerts
  • Support inbox unifying rider tickets, guest tickets & assistant chats
  • Business accounts with auto-emailed monthly statements
  • Live dispatch board (Socket.IO) with driver map pins & ride queue

Riley — AI Dispatcher

One AI brain on the phone and the browser chat widget: same prompt, tools, booking rules, and knowledge base.

  • OpenAI Realtime GA (gpt-realtime) with structured tool calling
  • Anthropic Claude (Haiku / Sonnet / Opus) for ranking, RAG & OCR
  • 24-language support with per-tenant voice selection
  • Sub-second turn latency in production; barge-in supported
  • Vector-RAG knowledge base with confidence-threshold escalation

  • quote_fare required before booking; price read aloud
  • Payment method gated by tenant booking rules (cash vs card)
  • book_ride creates the ride + sends SMS & email confirmation
  • Twilio signature verification on every webhook (auditable)

Pricing Engine

Fully configurable, fully audited fare engine — no surge commitment baked in.

  • PostGIS zone polygons with per-zone multipliers
  • Holiday calendar multipliers
  • Quotes persist a FareEstimateRecord for the book step
