Quill:

Quill has adapted research-based writing instruction into a free, open source digital platform. Our activities help students develop their sentence construction and grammar skills and are designed as supplemental writing exercises. Quill offers prompts and exercises and delivers instant feedback to help students write, revise, and revise again until they are able to produce succinct, powerful sentences.
