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.
The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
