A fleet of crawlers working in parallel — discovering, structuring, and licensing web data for AI companies at scale.
Three steps, fully automated, running continuously.
Millions of pages across news, reference, technical, and community sites — discovered, prioritized, and crawled on a continuous schedule.
Pages are rendered, de‑duplicated, cleaned of navigation and ads, then chunked, tagged, and scored for quality.
Structured datasets are delivered via API, bulk export, or custom feed — under clear licensing terms.
