How we made this page
We asked each AI tool the same question, "What is the best diagramming tool?", with one fixed instruction: answer with a ranked list of specific products or businesses, and don't ask a follow-up question. We read the names from each answer in the order given. A name's place in the table comes from how many tools named it, then its average position.
ChatGPT, Claude and Gemini answered from what they already know; Perplexity searched the web live, which is why its list can include newer names. AI answers change week to week, so every answer carries its date. Nobody paid to be on this page. See our methodology.
