What is Diffbot?
Diffbot offers APIs that turn web pages into structured JSON without site-specific rules, together with a Knowledge Graph, web search and a natural language API for data and research teams.
Diffbot's products are Extract, Crawl, the Natural Language API, the Knowledge Graph, Web Search and LeadGraph. Extract uses a standard ontology of page types such as articles, products and lists, and applies trained models to each type. The Knowledge Graph comes from Diffbot's own independent web crawl. The company is based in Menlo Park, California, and offers monthly subscriptions without long-term contracts, plus free Startup-tier access for students and academic researchers.
Diffbot AI features and use cases
- Extracts pages without custom rulesComputer vision and natural language processing classify a page and read the fields that belong to its type, such as offer price on product pages or author on articles. Teams collecting data from many different sites no longer maintain rules for each site.
- Links entities across the webThe Knowledge Graph connects organizations, people and products found in the crawl through entity linking and relation extraction. Research and sales teams can query company data instead of collecting it from single websites.
- Analyzes text for entitiesThe Natural Language API processes documents of up to 10,000 characters per credit and returns entities and relations. Analysts can structure news or reports before loading them into their own systems.
What sets Diffbot apart
- Own web crawl and Knowledge Graph alongside extraction, operated on custom hardware in a California data center.
- Free Startup-tier access for students and academic researchers.

Questions to ask before you buy Diffbot
Diffbot processes data in its own California data center; a public DPA, subprocessor list or certification was not found on the pages checked in September 2026, so request them. Knowledge Graph exports cost 25 credits per entity, which adds up quickly. If the Knowledge Graph holds data on people, check your legal basis before using it for sales outreach.
