English CEFR Vocabulary Checker
Paste your English writing and explore the CEFR level of its vocabulary — from A1 to C2, including idioms and multi-word expressions.
YOUR TEXT · YOUR VOCABULARY PROFILE
What level is the vocabulary in your writing?
Paste a paragraph, essay, email or article. We’ll map the vocabulary we recognise across CEFR levels and find natural multi-word expressions.
A1 → C2CEFR profile
This CEFR checker analyses the difficulty of the words in your text, not your overall English level.
Use the buttons to show or hide CEFR levels and multi-word expressions. Turn off A1–A2 to focus on intermediate and advanced vocabulary.
Colour-coded vocabulary in your text
Your colour-coded text will appear here after you analyse your writing.

MORE THAN A WORD LIST
See the vocabulary inside your writing.
The checker profiles the vocabulary in your text rather than judging your overall English level. It recognises vocabulary across CEFR bands, works with many inflected forms, and looks for idioms and other multi-word expressions.
Important: CEFR vocabulary profiling is only one part of language ability. This tool analyses the vocabulary used in a text; it does not certify your overall CEFR English level.
Check CEFR word levels in real writing.
Use the checker to explore the CEFR level of recognised English words from A1 to C2. Rather than checking vocabulary in isolation, you can paste a paragraph, essay or email and see how different word levels are distributed across the text.
Explore idioms and multi-word expressions.
The checker can recognise many English idioms, fixed expressions and other multi-word expressions. Select a recognised expression in your analysed text to see its CEFR level, type, meaning and an example when that information is available.
Useful for Cambridge English and IELTS writing practice.
Preparing for a Cambridge English exam or IELTS? Use the CEFR Vocabulary Checker to explore the vocabulary in your writing, identify B2, C1 and C2 language and notice useful multi-word expressions. It profiles vocabulary; it does not grade your complete exam performance.
Turn the result into focused practice.
Use your vocabulary profile to notice the balance between everyday and advanced language, then practise words and expressions deliberately. For individual support, explore our Cambridge English courses or IELTS preparation.
About the CEFR Vocabulary Checker
What does the CEFR Vocabulary Checker analyse?
It analyses the vocabulary in your English text, groups recognised words by CEFR level, highlights multi-word expressions and provides lexical and sentence statistics.
Can I use it as a CEFR writing checker?
Yes, to explore the vocabulary profile of a piece of writing. It does not grade the complete quality of the writing or certify the writer's overall CEFR level.
How can I check the CEFR level of a word?
Paste the word in a sentence or include it in a longer piece of English writing, then run the analysis. Recognised vocabulary is colour-coded by CEFR band from A1–A2 through B1, B2, C1 and C2, so the tool also works as a CEFR word level checker in context.
Can I use this for Cambridge English writing practice?
Yes. It can help you examine the CEFR vocabulary profile of writing for Cambridge English preparation, including the presence of B2, C1 and C2 vocabulary and recognised multi-word expressions. It is not an official Cambridge writing checker and does not award an exam grade.
Does it recognise idioms and phrasal or multi-word expressions?
Yes. The checker has a dedicated multi-word-expression layer so recognised expressions can be analysed as units rather than only as separate words. Where dictionary information is available, you can select an expression to see its level, type, meaning and an example.
Can teachers download the analysis?
Yes. The report button creates a Word-compatible report containing the original text, colour-coded vocabulary and analysis.
