Overview

Diffbot is a knowledge extraction and web search platform structuring unstructured web data into actionable intelligence for AI agents and applications. Computer-vision models classify a page, render it, and hand back clean, structured fields, while natural language processing extracts entities and maps relationships between them.

Web Search returns live, structured results with under 300ms latency and can be self-hosted; Extract converts any webpage into structured data at similar speed; Crawl walks entire websites to build queryable datasets; and Knowledge Graph technology queries billions of people, organizations, products, and articles for structured, verified answers rather than raw search results.

Diffbot targets sales teams needing account briefings, financial due diligence professionals, OSINT analysts, development teams planning data migrations, and enterprises needing verified web data to ground their own AI systems. Pricing isn’t disclosed – contact sales for details.
