Mechanic Shop Deploys AI Receptionist Axle
|
6.2
A developer built Axle, an AI receptionist for his brother’s mechanic shop to answer customer calls and capture callbacks in real time. The system uses a RAG pipeline with 21+ scraped documents embedded by voyage-3-large into MongoDB Atlas, Anthropic Claude for grounded responses, and Vapi (Deepgram/ElevenLabs) for telephony and voice synthesis. It logs calls, escalates unknown queries, and aims to reduce missed revenue.
Scoring Rationale
Practical, well-documented implementation provides reusable RAG+voice patterns; limited by single-shop scope and anecdotal single-source reporting.
