Text Inspector analyzes English writing for difficulty, readability, lexical variety, and CEFR levels. Its overall difficulty score draws on more than 200 metrics, and its CEFR Level Checker gives levels for individual words along with their commonness and difficulty. The 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. The maker identifies language professionals, academics, and students as users, including people preparing teaching materials or tests and evaluating student work. An API lets people and organizations add its analysis and scoring to their own tools and products. English is fully supported; other languages may receive limited statistics or lexical-diversity information. The Free plan covers 250 words and automatically deletes data after six hours. The Standard plan is listed at £9.96 monthly or £59.76 yearly; Organisation is listed at £59.76 monthly or £358.56 yearly and allows up to 13,000 words, the largest stated limit. API access starts from £360 per year and includes 30 days to test free of charge. Analysis data and private analysis URLs are deleted after six hours; personal data may be stored in the EEA while an account remains active.
