Text Inspector

Purpose: Text Inspector analyses English texts and reports difficulty, readability, lexical diversity and CEFR levels.
Metrics: The product says it provides an overall difficulty score based on more than 200 metrics.
CEFR analysis: Its CEFR Level Checker provides a CEFR level for individual words, including their commonness and difficulty.
Included tools: Listed tools include Statistics and Readability, Lexical Diversity, Scorecard, Tagger, EVP, BNC, COCA, Academic Word List and Phrases, Knowledge-Based Vocabulary Lists, and Metadiscourse Markers.
API integrations: The API lets people and organisations incorporate Text Inspector analysis and scoring into their own tools and products.
Intended users: The maker describes the tool as useful for language professionals, academics and students, including preparing teaching materials, tests and evaluating student work.
Language support: Text Inspector fully supports English texts; it may provide limited statistics or lexical diversity information for other languages.
Text size limit: The FAQ says the Organisation subscription's 13,000-word limit is currently the largest available because of server restraints.
Data retention: The FAQ says analysis data is cleared from the website after six hours and each analysis has a private URL that is deleted from the servers after that time.
Privacy and storage: The privacy policy says personal data is stored in the EEA for as long as the user has an account, and that users can delete their account at any time.
Support: The maker directs users with questions or issues to its help team by email at [email protected].
Company: The pricing page identifies Weblingua Ltd as the company behind Text Inspector and gives its England and Wales registration number as 11275226.
