Cognitive Content Analyzer


The Blobinator cognitive content analyzer plugin for WordPress provides deep text analysis of your posts, pages, and product listings. With our cognitive approach to content analysis, you can get an objective review of your tone, discover hidden keywords and concepts buried within your content, and explore the emotions your articles are projecting. Use these discoveries to adjust your writing style to your target audience and optimize search engine indexing through cognitive automatic tagging and linking related keyword tags to your content. Works with both article content and product descriptions, like WooCommerce.

Features of our free WordPress plugin include:

  • Tone & Sentiment analysis (positive, mixed, neutral, negative)
  • Emotion detection and breakdown
  • Keyword and related keyword extraction
  • Concept extraction and discovery
  • Cognitive tagging: automatically tag your content

Please give us many stars if you like the cognitive magic!
