DriveThruAI is an autonomous voice-powered drive-through ordering agent that replaces human operators with an intelligent conversational system. The agent retrieves real-time menu and offer data automatically using a backend scraping engine and n8n workflows, processes customer input, and responds using natural ElevenLabs voices. The frontend kiosk interface is built using Bolt, creating a clean, interactive UI that simulates a real drive-through screen.

The user problem we solve is slow, inconsistent, labor-dependent ordering at drive-through restaurants. Customers typically wait in long queues, miscommunication happens often, and upselling is inconsistent. DriveThruAI eliminates this by enabling fully automated ordering, dynamic upsells, and fast interactions.

The core flow is:

Backend scrapes or ingests menu/offers from the restaurant website.

n8n automatically cleans and structures this data and posts it into the backend via secure webhook.

The kiosk UI (built in Bolt) displays the live menu.

User speaks or types an order → the agent parses it, recommends upsells, and speaks back using ElevenLabs TTS.

Order is stored in Postgres and a QR code is generated for payment.

Admin dashboard displays orders in real-time.

The submission runs end-to-end using Docker Compose: backend, database, kiosk agent, and n8n automation all work together. During the demo, judges will see the website data scraped, pushed to backend via n8n, shown live in the Bolt UI, and processed by the agent using ElevenLabs voice output. and it’s not fully fuctional
