I have used Text Inspector since 2018 when I embarked on a research project examining reading texts to develop CEFR aligned reading tests. Using TI tool to help guage the reading level of each texts made it easy for my team to select and determine texts that are appropriate for each CEFR level A1-C2. We especially appreciate the text analysis tools that helped us to distinguish each level of text type from that of another level at a deeper level compared to other available text analysis tools.
I am an item writer for a number of exam boards that offer exams in English as a second or foreign language. Text Inspector has become an indispensable tool for me in creating test items appropriate for different language levels and age ranges. It is easy and quick to use, and allows differentiation by language skills required and a flexible approach to reporting. I can unreservedly recommend it to those who work in exam preparation.

Text inspector was crucial to identifying reading ease as well as CEFR levels for when we were writing reading comprehension assessments. I was able to enter lengthy texts and look at the data. I always have my own idea of what a text level is and found that the text inspector confirmed this. Included in the data was a breakdown of lexis CEFR levels and this was extremely useful as I was able to use this data to explain to colleagues why some texts we wanted to use were either suitable or unsuitable for assessments.
Using the latest research into Applied Linguistics, our tool is trusted by universities, colleges and organizations across the world, including:
