AI search · cases and method
People ask AI assistants before they search. These cases show what they answer and who they name.
The same questions go to ChatGPT and Claude in each language. Every answer is stored, and every brand named and every link cited is counted. Each case publishes its method and its data.
Built and run by Theis Parker Frost, Copenhagen, with AI coding agents.

How it works
From a question list to a number you can check.
Question set
Questions grouped by intent, written per market and language.
Collection
Each question goes to the assistant with web search on, twice.
Storage
Every raw answer is kept, so a number can be traced to its answer.
Extraction
Each cited link gets a domain and a source type from a rule list.
Scoring
Shares, rates and stability per market and question type.
Review
A person checks the result before anything is published.
AI agents do the collection and the first draft. They do not send email, log in to accounts or spend money. The full description, with limits, is on the method page.
What it measures
Six numbers, each with a written definition.
The same definitions apply in every market and for every assistant, so results can be compared.

Source influence
Which sources an assistant leans on in each market.
