I measure what AI crawlers actually receive from a site, and build the instruments that do it.
This page is a register, not a portfolio: every claim links to where you can check it. Full register, proof table and research notes: emmanuelorta.com.
- CrawlCheck — the verification layer for the agentic web: one signed answer about any site that an AI agent can check before it reads, cites or acts. It fetches the site as 15 client identities and measures 35 sections, 24 of them graded, across reach, read and quote. Free audit, no account. The findings are an open dataset: crawlcheck.io/data.
- SpeciesVault — lineage registry for captive-bred animals: accession numbers, derived generation chains, Darwin Core export.
