Tavily vs Diffbot: overview
Tavily
Tavily, founded by CEO Rotem Weiss, sells a search API designed for LLM agents. Its topic=news mode limits results to recent news and returns extracted text that can go straight into a prompt. Nebius, the Nasdaq-listed AI cloud company, agreed to buy Tavily in February 2026 (Bloomberg reported a $275 million price) and later said the deal had closed, with the Tavily brand and pricing kept in place. Billing runs on credits: one per basic search, two per advanced search, about $0.008 each on pay-as-you-go, and 1,000 free credits a month. As a search tool it has no news archive, source taxonomy or clustering.
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.
