How appropriate are your texts for German learners? Are they A1, A2, B1 or higher? The Language Level Evaluator (LLE) checks the difficulty of German texts using a range of measurable criteria. Get the full picture on our page LLE Deutsch.

Please note: LLE Deutsch Lite only separates the words of a short text into the different CEFR levels (lexical analysis). You can upgrade at any time to LLE Deutsch Pro for more powerful features, such as the ability to analyze longer texts, semantic analysis and grammatical evaluations.

Who did we develop the LLE for?

The LLE is primarily a supportive tool for selecting suitable reading texts and/or optimizing them for foreign language learning. We have specifically developed this tool for:

  • Publishers who have language learners as a target audience and therefore require a competent assessment of the CEFR language level of their contents.
  • Teachers of foreign languages who want to check whether the text material they create or adapt is suitable for the language level of their students.
  • Writers who want to optimize their texts for specific language levels using detailed analysis results.
  • Test creators who want to quickly create vocabulary lists or verify that their contents are suited to a specific learning level.
  • Us! We use the LLE for our language learning app StoryPlanet, in which we offer language-level specific reading texts and other content for learners.

State funding

We would like to express our sincere thanks to the Hessen Agentur and the LOEWE 3 program, which made the collaboration with the Technical University of Darmstadt possible from 2017 to 2019.

The initial stages of the LLE project were also supported by local ERDF funding from the City of Offenbach am Main from 2013 to 2015.
