How We Built an AI That Never Halluccinates

If you have ever used ChatGPT to answer a customer question, you have probably experienced the hallucination problem. The AI confidently states something that is completely wrong. It invents prices. It makes up opening hours. It recommends products you do not sell.

This is not a minor inconvenience. For a restaurant, a hallucinated "gluten-free" claim could be a health risk. For a law firm, invented legal advice could be negligent. For a car dealership, a fabricated price could cost thousands.

We decided to solve this problem permanently.

The dual verification system

Every answer Zivvo gives goes through two independent checks before it reaches your customer:

Check 1: Fact grounding (LLM verification)

A second AI reads the response and compares every claim against the source documents. "Does the response say the haircut costs 45 pounds? Is that price in the uploaded price list?" If any claim cannot be traced back to the documents, the response is blocked.

Check 2: Arithmetic verification (Java, not AI)

A deterministic Java program checks every number in the response. If the AI says "gel manicure (25) plus pedicure (30) = 55", Java independently verifies that 25 + 30 does indeed equal 55. No AI involved in the math check. Pure arithmetic. Cannot itself hallucinate.

What happens when verification fails?

The response is not sent. Instead, the question is escalated to you, the business owner. You get a notification on your phone. You reply. Your customer gets your answer. And the AI learns from your reply so it gets it right next time.

The result: zero hallucinations across 12 industries in our test suite. Not "low hallucination rate." Zero.

Why this matters for your business

Your customers trust you. When they message your business, they expect accurate information. An AI that makes things up destroys that trust faster than no AI at all.

With Zivvo, every answer is either verified correct or escalated to a human. There is no middle ground. No "the AI is usually right." No "it gets better over time." Every single response, verified or escalated.

That is the standard your customers deserve.
