What does Quill.org do?
Quill.org is a free online literacy platform for K-12 students. It replaces multiple-choice reading quizzes with AI-powered writing prompts that ask students to read nonfiction texts and respond with evidence-based claims. The platform also offers a full set of grammar and writing tools: sentence combining exercises, proofreading passages, diagnostic assessments, and whole-class lessons. Everything is aligned with Common Core standards and designed to fit into a typical classroom period of about 10 minutes per activity.
The platform works by giving students instant feedback on their writing. When a student combines sentences or proofreads a passage, Quill.org highlights errors and offers targeted suggestions to improve clarity and precision. The diagnostic tool pinpoints which skills a student needs to work on and builds a personalized learning plan. Teachers get detailed reports that show class-wide trends and individual progress, so they can intervene where students struggle most. The newest feature, Quill Reading for Evidence, uses AI to generate open-ended writing prompts from nonfiction texts, coaching students through multiple revisions to build deeper comprehension.
Quill.org is built for teachers who want to spend less time grading and more time teaching. It works with Google Classroom and Clever for one-click setup, making it easy to adopt. More than 44,000 schools already use it, and it's completely free — no ads, no hidden costs. The real-world use case is straightforward: a teacher assigns a 10-minute proofreading activity, students get immediate feedback, and the teacher uses the report to plan tomorrow's lesson. For ELL students, diagnostics are available in 13 languages. It's a practical, no-frills tool that does exactly what it promises.
