TextRazor
Natural language processing API that extracts entities, topics, relationships, and keyphrases from text across 19 languages.
About
TextRazor provides a deep NLP API for developers who need to understand the semantic content of documents, articles, or social media posts. It identifies named entities and disambiguates them with links to knowledge bases, extracts keyphrases, classifies content using IAB and IPTC taxonomies, and maps typed relationships between concepts within text. The API supports 19 languages and can be deployed as a cloud service or self-hosted for organizations with data residency requirements. A free tier gives 500 requests per day, with paid plans starting at $200 per month for higher volume and no long-term contracts.
