Generates leveled versions of a reading passage with vocabulary and comprehension questions.

What it is good at

Does one job well — takes a source text and produces genuine reading-level variants with aligned vocabulary support. Accepts a URL, pasted text or a topic, and exports to Google and Microsoft formats. Multilingual output makes it directly useful for language teaching.

Use it for

Generating leveled versions of one reading passage for a mixed-proficiency section so every student discusses the same content. Producing a simplified version of a research abstract for students not yet fluent in academic register.

Where it falls short

Built and marketed for K-12, so leveling targets grade bands and simplified output can read as childish to adult learners. Simplification sometimes strips the qualifications and hedges that make an academic claim accurate, quietly turning nuanced findings into overstatements. Generated comprehension questions are frequently shallow recall items needing rewriting.
