Press 0 for drama, 1 for Axle
I Built an AI Receptionist for a Luxury Mechanic Shop – Part 1
AI answers the phone, wallets cheer, ‘luxury’ purists boo
TLDR: A mechanic’s brother built “Axle,” an AI receptionist to stop missed calls and keep pricey jobs from slipping away. Commenters split: luxury-lovers want a human voice, pragmatists love the savings, and a side debate rages over whether the fancy tech is overkill or just good guardrails.
A luxury mechanic’s brother built “Axle,” a phone-ready AI receptionist that knows prices, hours, and policies, and only answers from the shop’s own info. The goal: stop losing jobs when no one picks up. It even uses a safety trick called RAG (the bot looks up answers instead of guessing) so it won’t quote $200 for a $450 brake job. Cool, right? Cue the comment brawl.
The loudest reaction: “Luxury means a human.” Critics say the word “luxury” and a robot voice don’t mix. One summed it up as, if you’ve reached the phone, you need nuance—not a website read-back. Another dunked with the meme-y line “clanker != luxury.” Meanwhile, a practical camp shrugged: this will save money and most callers won’t care—as one put it, their parents wouldn’t notice or mind if the bot just books them.
Nerd fight of the day: Is RAG overkill? Some say a few prices and hours don’t need fancy lookups—just paste it all in. Others argue the structure helps avoid “oops” quotes and keeps answers tidy.
Bottom line: DIY family fix meets vibe police. Fans cheer the hustle and faster pickups; haters insist “luxury” means a real person. Either way, Axle just rolled onto the phone line—and the comments are revving.
Key Points
- •The project builds a custom AI voice receptionist (“Axle”) to answer a mechanic shop’s calls and reduce lost revenue.
- •A RAG pipeline powers accurate answers using a knowledge base of 21+ documents scraped from the shop’s website.
- •Embeddings are created with Voyage AI (voyage-3-large) and stored in MongoDB Atlas with Atlas Vector Search for retrieval.
- •Anthropic’s Claude (claude-sonnet-4-6) generates responses constrained by a strict system prompt to avoid hallucinations.
- •Telephony integration uses Vapi with Deepgram (STT), ElevenLabs (TTS), a FastAPI webhook, and Ngrok for development exposure.
