Methodology
- Engines measured: ChatGPT (search), Perplexity, Gemini (grounded), Google AI Overviews. Google AI Mode is additionally sampled on a subset of queries; sample sizes are too small for a fair leaderboard and are excluded.
- LLM leaderboard: 10 fixed unbranded prompts, identical across engines, responses logged and cited-source domains counted. Branded prompts are excluded from this table by design.
- AI Overview share: real Google results pages for tracked study queries; branded queries excluded. A citation = the domain appears among an AI Overview’s linked sources.
- Cohort: 32 student-facing homework/study tools tracked continuously. Every number is a direct count from logged responses — nothing is modeled or estimated.
- Published by FastSolve. FastSolve is part of the measured cohort; the LLM leaderboard uses only unbranded prompts and AI Overview share excludes branded queries. All numbers are direct counts from logged engine responses.
