Issue 07 · The front desk 25 attacks. 25 holds. And the scoreboard is public, so you don't have to take my word for any of it. I built an AI receptionist for a plumbing company, put it on a live page, then spent a day trying to wreck it on camera. Haggling it down. Jailbreaking it. Baiting it into quoting a number it had no business quoting. It held all 25 times. If you came here from the video, this is the thing I promised: the full write-up, the checklist, and the exact guardrails that made it hold. If you didn't, the 5-minute version is here, or just keep reading. 5 price probes, 9 guardrail probes, 3 safety probes, 8 booking tasks. Every number is from a real run, and it updates in public. Go try to break it yourself. What it actually does Strip the pitch off and here is the job. Somebody's kitchen sink is clogged. They call. The AI works out the service zone, quotes the flat rate, offers real appointment slots, takes their details, and drops the booked job onto the dispatch board with a confirmation text. Nobody on my end touches it. At 2pm it runs exactly like it runs at 2am. For a business bleeding missed calls, that is the whole value. A real plumber I looked at was missing 47 calls a month. If even 5 of those were real jobs at a couple hundred dollars each, that is a thousand dollars walking to a competitor. Every month. That is the hole you are trying to plug. The honest part Here is what the demo videos skip. Some of your customers are going to hate this. I went digging through the small-business forums on Reddit, where owners say what they actually think instead of what a vendor wants to hear. One said he would rather be told to leave a message than be told a business does not care enough to answer. That feeling is real. If people choose you because you always pick up, putting a bot in front of them is a downgrade, full stop. There is a quieter cost too. It is a thing to maintain. Prices change, services change, and somebody has to keep the AI honest about all of it. That is why the last section of this issue is a checklist for when to skip the whole idea. An honest no now beats an angry refund later.
The exact guardrails that made it hold This is the part I care about most, and the third thing I promised in the video. Anyone can make a bot answer a phone. The whole game is what it does on the calls that are not simple. So I ran 25 probes at it across four categories: does it hold the price, can it be jailbroken, does it do the right thing in an emergency, and does it still book the real jobs. Here is what held.
25 for 25. Here is what holding the price looks like, pulled straight from the test transcript:
The real number, quoted clean, and it will not move off it no matter how you push. Here is the thing that took me a while to understand. The gap between the 80-dollar bot and the 15,000-dollar build is not the AI. The underlying model is nearly the same. The gap is the guardrails. Stopping it from inventing prices, stopping it from caving on discounts, making it hand off to a human at the right moment. That is the hard part, and that is the actual thing you are paying for. Steal this Four rules that make a receptionist bot safe to put in front of real customers, whether it answers for a plumber, a law firm, or a dental office.
The checklist So, worth it or not. Here is the honest checklist, the same one I give people who ask me to build them one. Screenshot it. It will save you a sales call with somebody less honest than me.
The full argument, industry by industry, lives in the worth-it write-up. What it costs Real numbers, not vendor math. Here is the market as of now. You are not paying for the AI. That part got cheap. You are paying for the guardrails. I broke every tier down, including the per-call meters and cancellation traps nobody quotes you up front, in what an AI receptionist really costs, and put it head to head against a human answering service. That is the whole issue: the write-up, the checklist, the guardrails. The best next move is not to trust me. It is to go attack the demo yourself and watch it hold the line.
Rather build your own? The exact prompts are 9 dollars, and the whole working build, including the parts that broke and how they got fixed, is 39. Rather I just built and tuned one to your prices? That is the /start page, and you do not pay the rest until it is live and you like it. Or get the build free Get 3 friends to subscribe and the full front-desk build is on the house.

Next week, a different build, same deal: the thing I made, and the part you can steal. If you know a business owner who is losing calls after hours, send them this one. Talk soon, Some guy. Not an expert. Just building. |
