Text Analyser (CEFR) API
An AI tool that can analyze the langauge difficulty of your content, to help you select the most suitable content for language learners.
The only tool on the market that analyzes sentence structure and verb tenses in detail by listing them out instead of just giving a CEFR-level score.
The only one tool on the market that analyzes the suitability of a text for the purpose of teaching particular grammar points using grammar point frequency and levels of difficulty difference between the text.
Instead of just scaling from A1-C2 , Cathoven splits 10 more segments for a single level(I.e., the CEFR checker may assign you A1.7 instead of A1). This helps the learners choose the appropriate learning content and enhance the reading and writing ability.
With the largest CEFR words database in the world, combining all the available data from world-renowned institutions, Cathoven’s database is maintained by high-end AI and constantly updated.
Level Adaptor API
We have the unique capability to adjust the language level of your learning materials, making it easier or more challenging while keeping the content unchanged.

However Cathoven’s Level Adaptor can accurately adjusting the language level of the content to the exact level you want. You can try and see yourself.
