BUYER PROMPTS
What we asked, ranked by buyer intent These are the questions buyers type when they are close to choosing a tool, not when they are just learning. We rank them by how close the wording is to a purchase: price and budget questions first, then switching and "alternatives to" questions, then head-to-head comparisons, then "best tool for my kind of team". Each prompt was asked once in ChatGPT, Perplexity and Gemini, with no login, chat history or personalization. Full methodology
