Generative AI tool categories, a 200-tool stratified sample, and vendor training-data disclosures

The dataset answers both with counts from a single snapshot (26 September 2026) of 11,959 active AI tools. Tools are grouped into 18 functional categories and 165 subcategories.

For each category the files give the number of tools, the split between AI-native products and platforms that added AI features, and the stated policy on four questions: default training on inputs, availability of an opt-out, exclusion of business plans, and exclusion of API traffic. A sample of 200 tools, 11 or 12 per category, illustrates the classification with concrete cases, each with a risk level and data-sovereignty rating.
