QUILL Quill is an all-in-one writing tool for upper elementary, middle, and high school students that supports grammar, revisions, and lessons. When writing essays and reports, the proofreader and grammar features come in handy, and the connect tool helps students identify run-on and fragmented sentences. Students learn essential writing tips in real-time by receiving instant feedback on their writing. Quill also includes a lesson feature that allows teachers to lead instruction to the entire class as well as small groups. To reinforce what was learned, Quill's lessons include writing prompts, discussion topics, and independent follow-up writing activities. Finally, Quill has a diagnostics feature that shows teachers where their students need to improve. This tool generates personalized lesson plans for each student based on their previous app activity and performance. https://www.quill.org/
