What happened when an AI agent renewed my car insurance

Renewing car insurance is a chore. So I handed mine to an AI agent, and watched it do in minutes what usually takes me an evening. Then I looked closely at what it had actually bought.

Comparing quotes, re-entering the same details on five websites, digging out last year's documents, remembering to cancel the old policy: it's exactly the kind of task people will hand to an AI agent first. So why wouldn't you? I asked Grok to sort out my renewal, end to end.

What the agent did

1. Found last year's policy. It searched my email and pulled out last year's insurance certificate and policy details.
2. Got me five quotes. Using those details, it went through five insurers' websites and came back with five quotes to compare.
3. Bought the new policy. It went through the purchase flow and paid.
4. Asked about the old one. It asked whether I wanted to cancel my existing policy. I said yes.
5. Went to my old insurer. It opened the insurer's website and asked for a one-time passcode to log in.
6. Read the code from my email. It found the passcode in my inbox and entered it.
7. Cancelled the old policy. It logged in to my account and cancelled.

Five quotes, a new policy and a cancellation, and I barely lifted a finger. It saved me an evening.

AI can help people understand what they're buying

Speed isn't the only upside. Insurance products are hard to understand. Policy wordings often run to 50 pages, and very few people read them. AI is good at exactly this: it can read the whole document, pick out what matters for your situation and explain it in plain language. Ask whether you're covered when your partner drives, or what the excess is on a windscreen claim, and you get an answer in seconds rather than a search through the small print.

Done right, that means people end up with cover that suits them, and that they actually understand. That's better for them and better for insurers. But only if it's done right. An agent that skims the documents and buys anyway, or answers questions about you without asking you, doesn't improve understanding. It just moves the gap somewhere harder to see.

What can go wrong?

I ran the same task several times. The results weren't the same each time, and none of them were quite right.

• My partner wasn't always on the policy. Sometimes the agent added my partner as a named driver. Sometimes it decided not to, because the quote form didn't clearly say it was required.
• It never checked what might have changed. Every time, it carried over last year's answers: the condition of the car, the assumptions behind the quote, and anything else that could have changed in a year. It didn't ask me about any of it.
• It told me to check, but never made me. The purchase flow said I needed to check everything was correct. The agent passed that on, then completed the purchase without me actually confirming anything.

What does this mean?

These are the kind of mistakes you only find out about when you make a claim. If the details on the policy are wrong, the insurer can refuse the claim or pay out less. And if my partner drives the car without being on the policy, they're driving without insurance, which in the UK is a criminal offence.

The insurer has no way of knowing any of this happened. From their side, a customer went through the quote, ticked the declarations, and bought. Nobody actually read them.

Why we built HumanApproved™

We're excited about people comparing and buying insurance with AI agents. It's faster, it finds better prices, and it takes a real chore off people's hands. But the last step can't be left to the agent.

HumanApproved™ adds that critical last step. When an AI agent reaches payment, the purchase pauses. The customer gets a link to a page that shows them exactly what's being bought, including who's covered, the key details the price is based on, and the main exclusions. They approve it themselves with a one-time code. Then the agent completes the purchase, and the insurer gets a signed record linked to the quote.

Insurers can then sell through agents knowing each customer has checked and approved what they bought.
