An ongoing study of the brands AI assistants name when buyers ask for tools. We run the real buying questions across six engines, count who gets recommended, and publish the results in full.
We ask the non-branded questions buyers actually type, not vendor keywords.
ChatGPT, Claude, Gemini, Google AI Overviews, Copilot, and Perplexity, measured side by side.
Every leaderboard, method, and per-brand breakdown is open. No gate on the findings.
New categories added regularly.
Buyers have started asking AI assistants what to buy before they visit a single vendor site. The assistant's answer, which names three or four tools and skips the rest, increasingly decides who makes the shortlist.
Almost no one measures this at the category level. The Answer Engine Index does, using the same method every time, so the results are comparable across categories and over time.
Lil Big Things runs these studies. If you want your own category measured, we can run it as a custom engagement. Talk to us →
