Cost advantage (the token test)

Is showing up in AI expensive? With AI Index, ~95% cheaper.

When an AI reads your raw HTML it processes a lot of text — and you pay per token. AI Index delivers ready-structured knowledge, so the AI uses a fraction of the tokens. In our production load tests:

Why being "found by AI" became essential

More and more people search straight in AIs instead of Google. In those answers the AI cites a few companies and ignores the rest. If your site is not structured for AI, you disappear exactly when the customer decides.

SEO vs GEO: the new optimization

SEO is showing up on Google. GEO (Generative Engine Optimization) is showing up in AI answers. AI does not read your site like Google — it needs structured knowledge. AI Index does this automatically, with sources citing you back.
