AI Text Leveler: Adjust Reading Level for Any Text
Ms. Johnson teaches 8th-grade science in a class with reading levels ranging from 5th grade to 11th grade. Her textbook is written at a 9th-grade Lexile level, accessible to half the class, too hard for the other half. She pastes the chapter section into the text leveler, selects 6th-grade band as the target, and gets a leveled version of the same content in 30 seconds. Same facts. Same concepts. Accessible language. She prints both versions for the same lesson.
The AI Text Leveler is one of 9 AI tools built into OpenEduCat. It serves teachers who need differentiated reading materials at multiple levels without rewriting passages by hand.
How It Works
From any text to a leveled version in four steps, content accuracy guaranteed.
Paste the text to be leveled
The teacher pastes any text, a textbook passage, a Wikipedia article, a primary source document, a science journal abstract, a news article, or any other written content. The AI reads the text and calculates its current Lexile level and grade-level equivalent. This baseline is shown before any adjustment is made.
Set the target level
The teacher selects the target level using one of three methods: Lexile number (e.g., 750L), grade band (K-2, 3-5, 6-8, or 9-12), or ELL tier (Beginner, Intermediate, or Advanced). For ELL adaptation, the teacher also specifies the content language, science texts get different vocabulary treatment from history texts at the same tier level.
AI rewrites while preserving factual content
The AI rewrites the text to the target level. Complex sentence structures are simplified. Academic vocabulary is replaced with accessible synonyms (or defined inline for ELL learners). Passive voice is converted to active where possible. Crucially, the core facts, concepts, arguments, and information remain entirely intact, the AI is adjusting language complexity, not changing the content.
Review side-by-side and save or export
The original and leveled texts appear side by side. Vocabulary changes are highlighted, new words in blue, simplified words in amber. The teacher can restore any word to the original, request an alternative phrasing, or accept all changes. The leveled text saves to the OpenEduCat resource library or exports as a Word document or PDF for printing.
Leveling Options for Every Classroom Need
Lexile precision, grade-band simplicity, or ELL-specific adaptation, your choice.
Lexile Scale Output
The Lexile Framework is the most widely used reading measurement system in the world. The AI outputs the Lexile level of the original text and the leveled version, so teachers can confirm the rewritten text falls within the target Lexile band. Lexile levels are shown as a range (e.g., 600L-700L) to account for the variation across a grade-level band.
Grade-Band Targeting (K-2, 3-5, 6-8, 9-12)
Teachers who do not need Lexile precision can select a grade band. The AI adjusts vocabulary, sentence length, and structural complexity to match the reading expectations of the selected band. A middle school science teacher can take a high school chemistry textbook passage and produce a version appropriate for 6th-grade readers without losing any of the scientific content.
ELL Adaptation (3 Tiers)
English Language Learners have different needs from below-grade-level native English readers. ELL adaptation goes beyond simplifying vocabulary, it also adds inline definitions for academic language, reduces idiomatic expressions, shortens and clarifies complex sentence structures, and for Beginner tier, uses high-frequency vocabulary. The ELL output can be used alongside the standard version for mixed classrooms.
Vocabulary Highlighting
In the side-by-side comparison view, every word that was changed is highlighted. Green highlights show words that were simplified. Blue highlights show new words introduced for extension versions. Teachers can click any highlighted word to see the original word, the replacement word, and the AI's explanation for why the change was made. This helps teachers decide whether to accept or restore each change.
Side-by-Side Comparison
The original and leveled texts are displayed side by side for review. Paragraph alignment is maintained so the teacher can trace how each section was rewritten. For ELL adaptation, a third column shows the inline definition layer. This comparison view is also useful for classroom use, students can read the leveled version while the original is displayed on the board.
Batch Processing for Full Units
Teachers can upload multiple texts (all the readings for an entire unit) and specify a target level for each. The AI processes all texts simultaneously and returns a leveled version of each. A teacher preparing differentiated reading packets for a 4-week unit can level 12 different texts in the time it used to take to level one. All leveled texts save to the OpenEduCat resource library.
How Teachers Use the Text Leveler
Differentiating textbook readings is the most common use case. When a class has a wide range of reading abilities, the teacher can produce a scaffolded version of every textbook passage without writing anything from scratch. Students read their appropriate level and all participate in the same discussion because they all read the same content, just at different complexity levels.
Supporting English Language Learners goes beyond simplifying words. ELL adaptation preserves content rigour while removing language barriers. A student who arrived from Brazil six months ago can engage with grade-level science content if the vocabulary is adapted to their current English proficiency, they are not behind in science, they are acquiring English.
Primary source adaptation for history classes is a particularly valuable use case. Original 19th-century documents are written in language that is inaccessible to most K-12 students. The text leveler can produce an accessible version of any primary source while preserving the original meaning, allowing students to engage with real historical documents rather than summaries.
Research article adaptation for science classes lets teachers bring real scientific literature into the classroom. A journal abstract on climate research can be leveled to 7th-grade reading level, students are reading real science, not a simplified textbook account.
