What we measured

A frozen sample of consumer-brand answers from the October AIGROW Index, not a survey of buyers and not an evaluation of the brands.

Collected from 2026-10-05 to 2026-10-06: 5,040 successful answers across 20 countries and 9 categories. Each cell combines four locally worded questions. ChatGPT and Gemini answered each question three times; Claude once. This study excludes web-search answers and Grok.

Collection, counting and model details

The writer reads the already published October pages and the latest stored answer for each probe up to 2026-10-06T23:59:59.999Z. It checks every published brand count against that page before writing. No new questions, model calls or Index aggregation are run.

A brand counts once per answer, using the Index spellings and stored aliases. First means the first distinct name in the extracted list. Names are not newly merged across countries; a local subsidiary or differently named brand may remain separate. Unlike the public rankings, the downloadable study retains names seen only once.

There were 27 successful answers with no brand. They remain in the denominators. Failed calls are excluded. A tie is reported as a tie, and counts are descriptive: repeated answers are not independent consumer observations.

ChatGPT and Claude were collected through subscription command-line tools; Gemini through an API gateway. The country was named in the local-language prompt. We did not test geolocated public accounts. Model updates, personalization, the wording of a question and web search can change the answer.

Questions about the study

Does first place mean the best brand?

No. First means the first brand in the extracted list of an answer. It measures ordering in this sample, not product quality, suitability, market share or a promise of a future recommendation.

Why do the assistants have different answer counts?

Each country and category has four questions. ChatGPT and Gemini answered each three times, giving twelve answers each. Claude answered once, giving four. Pooled totals therefore give ChatGPT and Gemini more weight; compare assistants separately in the country tables.

Can I reuse the charts and data?

Yes, under CC BY 4.0. Credit AIGROW, link to this study and include the October dataset DOI. Each country page offers a chart and an image embed code with a link back. The CSV includes every counted brand, including brands named only once.

Do these answers represent the public chatbot apps today?

They are a frozen October 2026 sample from specific models and collection routes, without web search. Answers in a public app can differ with its model, location, personalization, prompt and date. We did not survey consumers or measure purchases.
