An award-winning tool created by leading linguistics experts

Using the latest research into Applied Linguistics, our tool is trusted by universities, colleges and organisations across the world.

Why analyse vocabulary?

Vocabulary forms the core building blocks of language.

A rich vocabulary makes the four core skills of speaking, listening, reading and writing easier and without it, learners can’t understand language, express themselves or be understood.

In the words of renowned British linguist, David Wilkins; “…while without grammar very little can be conveyed, without vocabulary nothing can be conveyed”

What our users say

Elaine, teacher and MA student in Spain

I analysed three main textbooks used in secondary schools in the region where I live to see how much key vocabulary they shared. Thanks to Text Inspector I discovered that the vocabulary they had was from a disproportionately wide range of levels, from A1 to C2. I also found a high proportion of vocabulary not listed. Thanks! Text Inspector formed an important part of the investigation.

Williams, Sarah. Text inspector [online]. English Australia Journal, Vol. 33, No. 2, 2018: 80-83.

This system is ideal for language professionals, academics and students conducting
linguistic research. Overall, I found Text Inspector to be a fascinating tool to explore. It is fast and comprehensive, taking a matter of seconds to produce pages of data, and it allows users to analyse reading, writing and listening texts with great accuracy and reliability. I recommend all English language institutions and teaching professionals wishing to ensure that their materials are pitched at the right level utilise Text Inspector.
