How the AI Index works

We track what large language models actually say — repeatedly, over time — and turn it into the rankings on this site.

What we do

1. Ask real questionsFor each industry we maintain a set of real buyer questions and ask them to AI engines on a recurring schedule.
2. Capture the full answerWe record the engine's complete response and every source it cites, with a timestamp — currently 3451 answers across 2 industries.
3. Extract products & sourcesWe identify which products the answer recommends and which pages it cites, then aggregate across all questions and dates.
4. Update continuouslyBecause AI answers change, we re-run and refresh — so rankings reflect what AI says now, not a one-off snapshot.

What "% of answers" means

A tool's score is the share of tracked answers in which an engine names it. "Sources" counts how often a domain is cited across those answers.
