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 6378 answers across 4 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.
