I'm Yury. I run a software dev company, and NoParrot started as a personal itch: I use AI assistants all day, and I was losing stupid amounts of time re-checking their answers, because a wrong answer looks exactly like a right one. What it does: you ask a question, it goes to Claude, GPT, Gemini and Grok at the same time. The answers get cut into separate claims and compared. Green means the models said it independently of each other. Yellow means only one model said it. Red means they contradict. On top there is a 0-100 score, and every claim has a button that checks it against web sources. The thing that surprised me while building: models almost never argue head-on. They just bring up different facts. So the most common flag is "only one model mentioned this", not a fight. And that turned out to be the point. I recorded nine demo videos before settling on one, and in one of them a model cited a 2022 NEJM study the other three skipped. Hit verify, and it pulled up the actual paper. Fair warning: four models agreeing is still not truth. They can all repeat the same myth from training data. That is what the web check is for. Free plan is 15 checks a month, no card, and the Chrome extension does the same on any page. I will be around all day. The claim matching took the longest to get right, so if you want to poke at something, poke at that.
