Ask a second AI to check the first one’s work
4 October 2026 · 2 min read
What happened
Last night two AI assistants from two different companies worked on my game. Whichever one wrote a piece of work, the other had to check it before it was allowed in. Neither could approve its own work.
Seven pieces of work went in overnight. Five of them came back from the checker with problems on the first try. Every one was fixed and checked again before it was accepted.
One of the problems mattered to my wallet. The tool that makes the game’s sound effects uses a paid service. The checker tested it and found it could ask for the same sound twice, and could go past the nightly limit I had set. The first AI had reported the job as done.
Before and after
Trusting the first answer
“Build this for me.” The AI says it is finished, so you use it.
→ Mistakes get found later, by you, usually at a bad moment.
A second pair of eyes
Open a different AI, or a fresh chat. Paste in the work and say: “Another AI made this. Check it for mistakes, risks and anything missing. List what you find. Don’t rewrite it.”
→ A list of problems to fix before you rely on it, not after.
Why it works
An AI that made something tends to agree with itself. A second one, asked only to find problems, has no reason to be kind. A different company’s AI is best, because it tends to make different mistakes. A fresh chat is the next best thing.
Asking for a list, not a rewrite, keeps you in charge. You decide which points are real, and you can send the list back to the first AI to fix. Check the fixes yourself before you trust them.
