Text Analysis

20 APIs

Text analysis APIs detect language, translate, score sentiment, extract entities and classify text. Compare supported languages, pricing per character or request, and data retention, since you are sending user text to a third party. For sensitive content, a self-hosted option keeps the text on your own servers.

LibreTranslate is open source, can be self-hosted, and needs no key on instances that allow it. Google Cloud Natural and Watson Natural Language Understanding offer entity and sentiment analysis, and Detect Language identifies the language of a text with an API key.
