AI-Powered Text Intelligence

Our AI tools use proven natural language processing algorithms that run entirely in your browser. Sentiment analysis uses a lexicon-based approach with valence shifting. The keyword extractor implements TF-IDF (Term Frequency-Inverse Document Frequency), the industry-standard algorithm for information retrieval.

The readability scorer computes Flesch-Kincaid Grade Level, Gunning Fog Index, Coleman-Liau Index, and Automated Readability Index — the same metrics used by educators and publishers worldwide. No API calls, no data collection.
