Original data on how AI shops.
We publish what we measure: which brands AI assistants recommend, with the prompts, the method and the data open. Use it, chart it and cite it. Journalists can get each edition early, under embargo.
The AI Shelf Index
Monthly, from the first edition
30 fixed shopping prompts across 10 categories, asked of ChatGPT, Perplexity and Gemini every month with web search on. The first edition is being collected and publishes once 90% of its answers are in.
| Category | Prompts | Data |
|---|---|---|
| Skincare | 3 prompts | CSV |
| Supplements | 3 prompts | CSV |
| Coffee | 3 prompts | CSV |
| Running shoes | 3 prompts | CSV |
| Mattresses | 3 prompts | CSV |
| Cookware | 3 prompts | CSV |
| Pet food | 3 prompts | CSV |
| Baby gear | 3 prompts | CSV |
| Apparel basics | 3 prompts | CSV |
| Home | 3 prompts | CSV |
Using the data
Free to use, with credit
Index data is published under CC BY 4.0. Quote it, chart it, recut it. The one condition is credit: name the GigaCommerce AI Shelf Index and the edition, and link to the category page you used (or to the Index page).
Every number on the pages is a count you can redo from the CSV. We keep each answer and the sources it cited; if you need the rows behind a figure, ask.
Limits worth repeating in print: these are API answers with web search on, not the consumer apps, which personalise. One run per prompt per engine per month, so treat a single month as a sample and the trend as the story.
