Quill.org’s free online tools help low-income 3rd-12th grade students become strong writers and critical thinkers. Quill uses natural language processing to provide students with immediate feedback on their work, enabling them to revise their writing and quickly improve their skills. Teachers are provided with free access to our research-based curriculum, and our nonprofit, open source organization works with academic researchers across the country to design and build its technology and curriculum. There are 30 million low-income K-12 students in the United States who struggle with basic writing, one of the most important skills people need to improve reading comprehension and advance critical thinking. We are aiming to help at least 10 million low-income students become strong writers and critical thinkers in the next five years, and we have already helped more than 1.5 million students from 10,000 schools across the United States. To accomplish our mission, Quill is supported by grants from the Bill & Melinda Gates Foundation, AT&T Foundation, and Google.org, among others. In Feburary 2018, Fast Company recognized Quill as one of the Top 10 Most Innovative Education Companies.
