Online CEFR Text Complexity Analyzer
This service allows you to analyze English text and determine its complexity level according to CEFR standards (Common European Framework of Reference for Languages). The analysis is based on a dictionary of 13,000 English words distributed across levels A1-C2.
How the text analyzer works
CEFR Levels
CEFR divides language proficiency into six categories: A1, A2 (beginner), B1, B2 (intermediate), C1, C2 (advanced). The analyzer determines the distribution of words across these levels and calculates the overall text complexity level.
