Cathoven AI Tools APIs

What is CEFR?

An AI tool that can analyze the langauge difficulty of your content, to help you select the most suitable content for language learners.

CEFR-level

SENTENCE STRUCTURE & VERB TENSES ANALYSIS

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.

A1.7 instead

UNPARALLELED DETAILED LEVELS

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.
