Overview

Diffbot is an AI-powered web data extraction and structuring platform that automatically reads websites and converts unstructured web content into structured, machine-readable data. Founded in 2011 and originally spun out of Stanford AI Lab research, Diffbot operates the world's largest automated Knowledge Graph, crawling over 1.2 billion public websites. The platform serves enterprises and developers who need to extract, analyze, and organize web data for applications like lead generation, competitive intelligence, news monitoring, and market research.

Key Features

AI-Powered Web Extraction - Automatically extracts data from websites using computer vision and machine learning without manual rule configuration.
Knowledge Graph - Maintains the world's largest automated Knowledge Graph with structured facts about entities, relationships, and attributes across the public web.
Extract APIs - Specialized APIs for extracting specific content types including articles, products, discussions, and custom data structures.
Custom API Builder - Allows users to define custom extraction rules using CSS selectors for domain-specific or non-standard data requirements.
NLP Processing - Natural language processing capabilities for understanding and structuring text-based content from web pages.
Bulk Crawling - Crawls entire websites or specified URL patterns to extract data at scale across multiple pages.
Entity Recognition - Identifies and structures entities like people, organizations, products, and locations from web content.
