An AI reading passage generator is a tool that creates an original, grade-leveled informational or narrative text on any topic you specify, paired with comprehension questions — in seconds. It's the opposite of a reading passage library: instead of searching through hundreds of pre-written texts hoping to find one that fits your topic and reading level, you describe exactly what you need and the AI writes it.
For ELA teachers and reading specialists, this changes the resource-gathering equation fundamentally. Static passage libraries like CommonLit, SuperTeacherWorksheets, or ReadTheory have fixed catalogs — well-curated, but finite. When you're mid-unit on a topic that isn't in their database, you're stuck improvising or spending time adapting a passage that doesn't quite fit. An AI generator has no catalog limits: it can produce a historically accurate, appropriately leveled passage on the Byzantine Empire, the biology of bees, or the economic impact of climate change, tailored to your exact grade level.
Lexile levels matter enormously in reading instruction. Research from MetaMetrics (the organization that developed the Lexile Framework) consistently shows that students make the greatest reading gains when they read texts within 50L–100L of their measured reading level. In a class of 25 students, you might have a reading range of 400L (2nd-grade level) to 900L (9th-grade level) within the same classroom. An AI generator lets you produce differentiated passages on the same topic at multiple Lexile levels — without triple the prep time.
Describe what the passage should be about. "The causes of World War I" is better than "History." "How plants make food through photosynthesis" gives the AI more to work with than "Science." You can also specify a narrative context: "A story about a girl who uses math to solve a community problem."
Choose a grade band (2nd–3rd, 4th–5th, 6th–7th, 8th–9th, 10th–12th) or enter a specific Lexile range (e.g., 600L–800L). The AI adjusts sentence length, vocabulary complexity, and conceptual density accordingly.
Choose Informational/Expository (facts about a topic; ideal for science, social studies), Narrative (story-based; ideal for ELA), or Persuasive/Argumentative (argues a position; ideal for teaching text structure and argument analysis).
Select short (200–300 words, for a warm-up or exit activity), standard (400–600 words, a full reading lesson), or extended (700–900 words, for deeper close reading or timed reading practice).
Copy the passage and questions to Google Docs for formatting, or download as a formatted PDF ready for print. Questions include an answer key section at the bottom of the PDF.

Yes. EasyClass generates original reading passages on any topic — from curriculum content (the water cycle, the Civil Rights Movement, multiplying fractions in word problem form) to student-relevant topics (social-emotional themes, current events, school community stories). It's completely free with no login required.
Select the Lexile range from the dropdown (e.g., 400L–600L for grades 2–3, 800L–1000L for grades 6–8) or choose a grade band. The AI calibrates sentence complexity, word frequency, and conceptual density to match the target Lexile. For precision leveling, you can paste the output into a Lexile analyzer tool to verify the measured level.
Yes — every generated passage includes 5 comprehension questions automatically. The questions span multiple cognitive levels: literal recall, inference, vocabulary in context, and text evidence. An answer key is included in the PDF export.
Yes. Run the same topic prompt multiple times at different Lexile settings. For example, generate a passage on 'the American Revolution' at 500L for below-grade-level readers and at 900L for advanced readers. Same essential content, different text complexity — without writing two completely different passages from scratch.
CommonLit and ReadTheory are libraries of existing texts — you search their catalog for something that fits your topic. EasyClass generates an original passage on demand for any topic you specify. If you're teaching a unit on a topic that doesn't exist in CommonLit's database, EasyClass fills that gap immediately. The two approaches are complementary — EasyClass for custom generation, CommonLit for high-quality literary texts with teacher discussion guides.
