Google Cloud Natural Language API

The Cloud Natural Language API analyzes unstructured text with Google's machine learning models, extracting entities, scoring sentiment, parsing syntax and classifying content. Developers use it on emails, chats, reviews and social posts to turn text into structured data.

Entity analysis finds and labels people, places, organizations and other items in a document, and sentiment analysis measures the opinion expressed overall or toward each entity. Content classification sorts text into categories, and a text moderation endpoint flags harmful content.

Pricing is per 1,000-character unit for most features, with the first 5,000 units of entity analysis free each month and lower rates at higher volumes. New Google Cloud customers get up to $300 in credits.
