Understanding CEFR Levels in Text

The Common European Framework of Reference for Languages (CEFR) categorizes text difficulty into six levels: A1 (Beginner) to C2 (Proficient). Our tool uses sentence complexity and vocabulary density to estimate where your text falls.

A1-A2: Basic

Short sentences, high frequency words, simple grammar. Suitable for beginners.

B1-C2: Independent/Proficient

Longer sentences, abstract nouns, complex connectors (e.g., 'notwithstanding').
