Diffbot vs Google Cloud Natural Language API: What are the differences?

Diffbot: A robot that sees the web the way people do, and helps developers extract the important parts from any web page. Our APIs use computer vision, machine learning and natural language processing to help developers extract and understand objects from any Web page. We've determined that the entire Web can be classified into approximately 18 structural page types. From this basic understanding of common page layouts, Diffbot then uses computer vision, natural language processing and other machine learning algorithms to identify and extract the important items from within these pages; Google Cloud Natural Language API: Derive insights from unstructured text using Google machine learning. You can use it to extract information about people, places, events and much more, mentioned in text documents, news articles or blog posts. You can use it to understand sentiment about your product on social media or parse intent from customer conversations happening in a call center or a messaging app. You can analyze text uploaded in your request or integrate with your document storage on Google Cloud Storage.

Diffbot belongs to "Article API" category of the tech stack, while Google Cloud Natural Language API can be primarily classified under "NLP / Sentiment Analysis".
