Diffbot vs Aylien News API: overview
Diffbot
Diffbot combines automatic web page extraction (Article API, Product API, Discussion API) with a continuously-updated knowledge graph of 10 billion+ entities including companies, people, products, and events. Its Knowledge Graph Search API queries this structured dataset using natural language rather than keywords, enabling precise entity-level retrieval beyond what SERP APIs provide. Diffbot was founded in 2010 by Mike Tung at Stanford University and is headquartered in Menlo Park, California. It uses computer vision and machine learning to extract structured data from any web page without custom selectors. Clients include Snapchat, DuckDuckGo, Cisco, and Goldman Sachs (per company website; independently unverifiable).
Aylien News API
Aylien News API (now part of Quantexa, acquired 2024) indexes 80,000+ news sources globally and enriches every article with Natural Language Processing: named entity recognition, sentiment analysis, IAB topic classification, and author extraction. This pre-processed enrichment layer separates it from raw news aggregators — callers receive structured signals rather than raw article text. The API covers 50+ languages and enables filtering by entity, sentiment, topic, country, source, and publication time. Aylien was founded in 2012 and is headquartered in Dublin, Ireland. Following the Quantexa acquisition in 2024, the News API product continues to operate under the Aylien brand (per company website; independently unverifiable).
