Our verdict

Supametas.AI extracts fields from complex web pages using natural-language prompts, walks through paginated and multi-level listings automatically, and outputs the result as standardized JSON or Markdown for a RAG knowledge base. Scheduled background updates keep a dataset current without manual re-scraping, which is aimed squarely at enterprises building their own industry datasets rather than individual hobby projects. Making real use of it still means having somewhere to plug that structured output into, since it stops at producing clean data rather than running the RAG system itself.

Aimed at enterprisesIt's built for enterprise-scale dataset building, not a single quick lookup.
Depends on source page structureExtraction accuracy depends on how consistently the pages being scraped are structured.
