Quill.org is a nonprofit literacy platform that offers free online tools to help students in elementary, middle, and high school build strong reading, writing, and grammar skills. Teachers can assign short, interactive activities—such as diagnostics, grammar practice, sentence combining, proofreading, whole‑class lessons, and the Reading for Evidence tool—where students read texts, write their own sentences, and get instant feedback that guides them to revise and improve. The platform integrates with systems like Google Classroom, provides basic reporting to track student progress, and keeps all core content and student activities free, with an optional premium layer for schools that want more advanced data and dashboards.
