Quill.org, the non-profit writing platform used by English-language arts, Social Studies, and STEM classrooms across the United States, announced today its students have completed 40 million hours of instructional practice by writing and receiving feedback on three billion sentences. With the national average cost for tutoring of $26 per hour, 40 million hours represents more than $1 billion in instructional value, elevating Quill into a rare class of “non-profit unicorns” that create ten-figure public benefit without pursuing commercial profit.
Since its 2014 launch, Quill has served 11 million learners in all 50 states — 63 percent of whom attend Title I schools. Quill’s approach to writing instruction starts with the sentence — the building block of all effective writing. Unlike other learning tools that rely on passive, multiple-choice practice, Quill engages students in active writing. Quill’s AI is designed to replicate the back-and-forth rhythm of a tutoring session, identifying areas of improvement in a student’s response and then posing targeted coaching and feedback like “Try introducing a stronger transition” or “Strengthen this piece of evidence in your response”.
Behind the scenes, Quill’s feedback model utilizes both Generative AI and additional rules-based feedback so that each piece of coaching to a student is both precise and conversational. While many education technology tools stop at simply grading a piece of writing, Quill keeps the conversation going. Students can write and revise up to five times on the same sentence, receiving targeted coaching and feedback after each attempt.
“Reaching the billion-dollar impact mark proves that advanced AI can advance equity, not just efficiency,” said Peter Gault, Founder and Executive Director of Quill.org. “Our mission has always been to give every student, especially those in under-resourced schools, the expert feedback that turns writing into thinking. Today’s milestone honors the educators who trust Quill and the funders who share our belief that literacy is the gateway to opportunity.”
This year’s growth has been fueled by venture-style philanthropy from The Patrick J. McGovern Foundation, Overdeck Family Foundation, Google.org, Axim Collaborative, Siegel Family Endowment, MIT Solve, and NewSchools, among others. Their critical support accelerated Quill’s new generative-AI pathways, expanded district-level analytics, and launched an “AI for Society” curriculum that helps students learn about how AI is impacting society.
With the billion-dollar benchmark achieved, Quill is doubling down on open-source R&D and curricular partnerships, utilizing the latest Generative AI models to develop new learning tools and instructional programs for students.
