AI Text Leveler for ESL Learners
ESL students face a dual challenge: they are learning content while simultaneously acquiring English. A 9th-grade student who arrived from Mexico three months ago is not behind in biology (she has grade-level science knowledge in Spanish. She is behind in academic English. Leveling the biology textbook to her English proficiency tier) reducing idioms, adding inline vocabulary glosses, shortening sentence chains, allows her to engage with grade-level science content while she builds English fluency. Her content learning does not need to pause because her language acquisition is in progress.

How Teachers Use It for ESL Learners
Real classroom scenarios where text leveling changes how students access content.
Science content access for Beginner-tier ESL students
A high school biology teacher has three newcomer ESL students at Beginner proficiency. The textbook is at 970L with complex passive constructions and academic vocabulary. She produces Beginner-tier ESL adaptations of each chapter section, short sentences, active voice, high-frequency vocabulary with inline definitions, and flagged points where a bilingual glossary insert would help. Students read real biology content instead of a simplified worksheet with no connection to the curriculum.
Intermediate ESL leveling for social studies
A middle school ESS teacher has 11 students at Intermediate English proficiency, they can hold a conversation in English but struggle with academic register. She uses the Intermediate ESL tier to level social studies passages: academic vocabulary is retained but defined inline, idiomatic expressions are replaced with direct language, and sentence length is capped at 20 words. Students can access the content arguments and participate in class discussion.
Advanced ESL bridge to grade-level text
Advanced ESL students are often one step below full grade-level reading proficiency. An ELA teacher uses the Advanced ESL tier as a bridge: the text retains full academic vocabulary but removes particularly dense syntactic constructions and adds clarifying transitions. After one semester of using leveled bridge texts, three students transitioned to the unleveled versions, the scaffold achieved its goal.
