Quantexa News API (Aylien) vs Diffbot: overview
Quantexa News API (Aylien)
Aylien was founded in Dublin in 2012 and built one of the more advanced NLP news APIs, pulling multilingual content from roughly 80,000 sources and tagging it with entities, categories and sentiment. Quantexa, the London decision-intelligence company, acquired Aylien in February 2023 for an undisclosed sum, and the product now goes by Quantexa News Intelligence and Quantexa News API. Quantexa's community forum still advertises a 14-day trial. A competitor, however, reports that new subscribers are being pointed to a customer notice, and Quantexa has published no roadmap for the standalone API.
Diffbot
Diffbot was founded in 2008 by Mike Tung and is based in Menlo Park, California, with an estimated 30–40 employees. It uses computer vision and NLP to extract structured articles from any web page, and its Knowledge Graph links articles to organisations, people and topics so it can be queried as a news source. A free plan includes 10,000 credits at five calls a minute, the Startup plan costs $299 a month for 250,000 credits, and exporting one Knowledge Graph entity costs 25 credits. Teams that want to assemble their own news collection get more from it than teams wanting a ready-made feed.
