Method
- We send 5 buyer-style questions (the same templates as our free check) to ChatGPT through OpenAI’s API with web search on, one search per answer, no personalization and no chat history.
- A small model lists the products each answer names; we count each product once per answer. Nothing here is edited by hand or sponsored.
- The sample is small and answers vary between runs, people and model versions. Use it to see who tends to get recommended and which sources are cited, not as an exact ranking.
- We re-run every category about once a week. This page shows the latest run only.
