Adaptive reading comprehension practice with instant data for every student
A quick benchmark assessment finds each student's true reading level in around 14 minutes, then the difficulty adjusts continuously as they practice.
Generate reading passages and questions on any topic in seconds, or choose from thousands of standards-aligned fiction and nonfiction texts written by real authors.
One dashboard shows growth, mastery, and gaps across every student, class, school, and district, reporting in Lexile, grade, and ELA standard terms.
Passages, quizzes, graphic organizers, and worksheets are available to print for small groups, substitute days, and screen-free lessons.
Free AI study partner that turns your course material into practice questions, guides and flashcards
Upload PDFs, DOCX, PPTX, images, MP4, MP3, notes or a YouTube link and get study material generated from it — over 90 supported file types.
Thea asks you questions drawn from your own course content instead of revealing answers, so learning happens through active retrieval.
The system tracks what you know and what you do not, then focuses your sessions on the material you have not yet mastered.
