This has a solid information hierarchy for a cargo-services landing page—the service-card row sets context before the focused hero section, and the warm image treatment keeps the otherwise neutral layout human. The repeated card pattern should also scale well on mobile.
🛠️ Show & Tell: AI Voice Receptionist — Retell AI + n8n + Google Sheets + Retool
Hey Contra community 👋
Just wrapped a full AI voice receptionist build for a home services client and wanted to share what went into it.
What it does:
Answers inbound calls 24/7 using Retell AI
Runs 3 real-time checks via n8n: service area · slot availability · customer lookup
Books the appointment live on the call — no double-booking
Logs to Google Sheets and fires a confirmation email automatically
Full Retool command center for the client to manage everything
The tricky part:
Retell AI has a toggle called "Payload: args only" — when enabled, it strips the parent wrapper from the webhook payload. Took a solid debug session to figure out why n8n kept returning empty data. Once I caught it and rebuilt the payload mapping, everything worked end to end.
Stack: Retell AI · n8n · Google Sheets · Retool MCP
Happy to answer questions on any part of the build — webhooks, n8n sub-workflow structure, Retool dashboard setup, whatever.
If you're a builder who gets overflow work in voice AI or home services automation, let's connect 🤝
Nice systems thinking in this build—the handoff between voice intake, availability checks, booking, and confirmation is clearly mapped to a real user outcome. The Retool command center also makes the automation legible instead of hiding it behind the scenes.
Why AI Is Still Unreliable ...
(and will probably remain like that)
Many today fear losing their jobs and businesses because of the rise of artificial intelligence. This is, of course, a justified fear that many people have. A machine that can generate long pieces of text in minutes, that can create incredible images and videos, that can generate code and translate discourses in over 150 languages.
Who hasn't thought of the possibility of AI replacing many of us, i.e., taking our jobs?
But there is a real-life example that shows why AI is unreliable and why humans will always be needed, even with the dawn of such interesting technology.
When AI Decieves Hundreds of People
A couple of days ago, hundreds of people landed in the city of Jurilovca, in Southeast Romania. There, many believe, was an annual fish festival, where people could listen to good music, drink wine, and, of course, eat fish.
However, things turn out completely wrong. There was no festival in this city, and nobody had ever planned for one in this city. The mayor did not know about it, not even the town's drunk.
So how did we end in such a situation?
The Failure of AI
The people who arrived in the city of Jurilovca were taken there by various travelling agencies. These agencies got the information that a fish festival would be held in the city from ChatGPT.
Yes, because ChatGPT told them that there will be a fish festival in that city, and many of these professionals in the tourism industry organized trips there without even verifying whether the information is correct or not. In other words, they entrusted ChatGPT, an LLM.
The Moral of the Story
ChatGPT is only a tool that can help you speed up certain tasks and be a helpful companion in research. However, it can never replace a human. Just like some people were fooled about a so-called fish festival in a small Romanian city, others might
- get pieces of code full of errors
- receive bad translations from one language to another
- craft articles full of misinformation and nonsense
- make plans that don't rise to the expectations
No matter how you put it, it is never a good idea to put your trust in AI blindly and completely.
