Project Description

AgentEats is an AI-powered phone-ordering system that answers restaurant calls 24/7, takes orders through a natural voice conversation, and sends the final order directly to the kitchen or POS with zero staff involvement and zero commission fees. It solves the real problem of missed phone orders, overworked staff, and expensive delivery-app margins.

End-to-end: A customer calls a restaurant’s phone number → our agent engages in a fully natural conversation → retrieves the real menu via live API → collects items, modifiers, and customer details → confirms the order → writes it into the kitchen system or POS → logs the interaction. The demo shows the complete flow live from a browser-based phone interface using ElevenLabs voice, OpenAI reasoning, and real menu integrations.

Judging Criteria

Working Prototype

AgentEats is fully functional: users can place real orders via a live voice call in the browser. The agent handles multi-turn dialog, menu lookups, item confirmation, error recovery, and order submission to a real Postgres-backed kitchen system.

Technical Complexity & Integration

The project integrates multiple systems in real time:

Next.js frontend with a live phone-call simulation UI
Clerk for authentication
ElevenLabs for low-latency voice input/output
Prisma + Postgres for menu, order, and restaurant data models
Railway for hosting, deployments, and database infrastructure

The hardest part: robust multi-turn conversational order-taking that stays grounded in the restaurant’s real menu, supports modifiers, handles mistakes, and maintains accuracy without hallucinations.

Innovation & Creativity

AgentEats replaces a traditionally manual, error-prone workflow with a fully autonomous AI phone agent. Instead of another chatbot or web-ordering widget, it uses voice-first natural conversation, grounded menu retrieval, and autonomous ordering logic to behave like a trained staff member that never sleeps. It’s designed to be drop-in simple for any small restaurant, so no training, no configuration, no extra hardware.

Real-World Impact

Restaurants lose thousands annually to missed calls and 20–30% commission fees. This solves both problems instantly by:

Capturing every order
Operating 24/7
Eliminating commission fees
Reducing staff load
Increasing revenue without hiring

Theme Alignment (Agentic Workflows)

AgentEats is built around a fully autonomous agent that handles an entire workflow from start to finish:
Receives an incoming call
Conducts the ordering conversation
Performs menu lookups
Executes confirmations and corrections
Finalizes and writes the order to the kitchen
All without human supervision or manual triggers

It’s a complete agentic loop that continuously acts, reasons, and executes tasks until the order is delivered to the kitchen.
