AI chatbots are designed to be helpful. The problem is they’re often too helpful. Ask most AI tools to evaluate your idea and you’ll usually get encouragement, polite suggestions and maybe a few minor tweaks. What you rarely get is the kind of blunt criticism that actually improves an argument.
That’s why I developed the “potato” prompt. The idea is simple: type the word “Potato” before your argument and instruct the chatbot to drop its friendly persona and act like a hostile critic.
Although I originally created for people-pleasing ChatGPT, the recent QuitGPT movement made me wonder how well it worked on Claude and Gemini. So, I decided to test the prompt on all of them to see which AI does a better job tearing apart bad logic.
