Quill.org is a non-profit dedicated to helping all students become strong writers, readers, and critical thinkers. Quill's six free literacy tools — Quill Diagnostics, Quill Connect, Quill Grammar, Quill Proofreader, Quill Lessons, and Quill Reading for Evidence — deliver immediate feedback and coaching to strengthen student writing and save teachers’ time. Through Quill’s library of 1,000+ differentiated activities, students in grades 4-12 learn to write by mastering sentence construction and write to learn by reading cross-curricular texts and responding to open-ended prompts. As of 2025, over 11 million students have strengthened their literacy skills with Quill, writing and revising over three billion sentences.
The core of Quill is its feedback. Here’s how it works:
Real-time analysis of student writing - As soon as a student submits a sentence, Quill’s AI checks it for specific skills (like subject–verb agreement, sentence structure, or use of evidence).
Specific, skill-focused feedback - Instead of a generic “correct” or “incorrect,” Quill points out the exact issue (e.g., "This sentence has a subject–verb agreement error") and often gives a short example or hint.
Multiple revision opportunities - Students can edit and resubmit their work based on the feedback, reinforcing the skill through immediate practice.
Adaptive learning paths - After a diagnostic or activity, Quill recommends follow-up activities targeted to each student’s needs, ensuring they spend time on the skills they haven’t yet mastered.
Supports different ability levels – Feedback is written in clear, student-friendly language, and in many cases is available in both English and the student's chosen language for better accessibility.
Quill's 1,000+ literacy activities across its six tools engage students in learning to write and writing to learn.
These tools include:
- Quill Diagnostics to assess student writing and measure growth
- Quill Connect to combine sentences using conjunctions like but, because, so
- Quill Grammar to practice grammar and mechanics
- Quill Proofreader to edit passages
- Quill Lessons to lead direct instruction
- Quill Reading for Evidence to analyze texts, identify claims, and support ideas with evidence.
As of 2025, over 211,000 teachers and 11 million students have used Quill. These students write over 500 million sentences a year. Over 41,000 schools use Quill in all 50 U.S. states and across the world.
Quill is designed to be highly flexible and easy to integrate into any classroom routine or curriculum. Most Quill activities take just 10–15 minutes, making them ideal for bellringers, homework, station rotations, or small group instruction. Our Reading for Evidence lessons may take slightly longer (up to 20 minutes), depending on how teachers choose to facilitate the discussion.
We recommend that teachers assign a diagnostic 1–2 times per year to identify skill gaps and generate personalized activity recommendations. From there, students should complete 2–3 recommended activities per week. In just 10–12 weeks, most students will finish their initial set of assignments — at which point a post-diagnostic helps measure growth and guide the next round of targeted practice.
As a non-profit, Quill provides all activities for free, forever. There is no limit to the number of activities you can assign or the number of students you can invite.
We also offer a premium service for in-depth reporting for educators, schools, and districts. Quill Premium is designed for schools and districts ready to make a systemic impact on literacy instruction. With features like schoolwide professional learning, advanced reporting, and priority support, Premium helps educators amplify student outcomes and build a cohesive, evidence-driven approach to writing instruction. You can learn about our pricing here.
As of 2025, Quill offers 1,000+ literacy activities covering more than 300 grammar concepts for grades 4-12. Our newest tool, Reading for Evidence, offers over 25 cross-disciplinary text and writing prompts to build reading comprehension for grades 8-12.

Welcome to Quill!
Once you've set up your classes, the best way to begin is with a diagnostic — it pinpoints where students need support and automatically recommends practice activities. Assign a diagnostic here.

We recommend implementing Quill activities with your students 2 to 3 times a week, each for 15-20 minute intervals. In addition, please see this Teacher Center article about how long Quill activities typically take and how frequently each type of Quill activity should be assigned.

While our activities are arranged by Common Core Standard, there is not a fixed progression of activities. Teachers have all of our activities available to them, and they may choose to assign any activity they're interested in teaching.
However, we recommend that teachers assign the Starter Diagnostic (Baseline Pre) to their students as a starting point. Learn more about how to assign a Quill Diagnostic here.
Quill's six tools engage students in learning to write and writing to learn.
These tools include:
Quill Diagnostics assess students' proficiencies in their writing skills. When a student completes a Quill Diagnostic, they generate a learning plan of recommended activities that focus on their performance on the Quill Diagnostic.
Quill Connect is Quill's sentence-combining tool and guides students to combine simple sentences into a more complex sentence using different writing skills. The prompts and targeted feedback help students advance from writing fragmented and run-on sentences to forming complex, well-structured sentences.
Quill Grammar helps your students practice basic writing skills, from comma placement to parallel structure. Students receive immediate targeted feedback for each response that they submit, which helps them strengthen their writing
Quill Proofreader teaches students editing skills by having them proofread text passages. After students edit the text passages, Quill provides feedback on the edits that they made. If students make any incorrect edits, Quill will provide a follow-up activity so that they may practice the writing skills with which they are not yet proficient.
Quill Lessons is our tool for interactive whole-class or small-group writing instruction. During Quill Lessons, teachers guide students through interactive slides that contain writing prompts, and students respond to the writing prompts and participate in discussions about the writing prompts. Quill Lessons include a downloadable Quill Lesson plan, a full Quill Lesson script, writing prompts, discussion topics, and a follow-up independent-practice activity.
Quill Reading for Evidence builds content knowledge and writing skills concurrently. During Reading for Evidence activities, students read nonfiction texts. Then, students paraphrase and synthesize evidence from the text to complete three sentence stems about a key idea in the text.
Quill offers six diagnostics and four skills surveys to help gather data on your students' needs. Once your students complete a diagnostic or survey, we'll create a set of recommended activities tailored for each student based on their diagnostic results. As the teacher, you can review these recommendations and assign them all or pick and choose the ones you'd like your students to complete based on your own evaluation of their needs.
You can also personalize instruction for your students by building your own activity packs. Search our entire library of content and build custom packs that can be assigned to your whole class, small groups, or individual students, giving you the freedom to assign activities that are specific to your students.

After each revision, students receive feedback on their writing. In consultation with teachers and based on current research on how to provide grammar instruction for students, we have made a few very intentional style decisions that we follow as we write this feedback. Here's an overview of some of the guidelines that our student-facing feedback follows:
All Quill activities are categorized by Common Core State Standards (CCSS) and specifically focus on the language standards where they choose to assign it to their students.
In Quill's activity library, teachers linked by clicking Readability Level or CCSS Grade Level in the menu of filters on the left side of the page.
We have a lot of activities in our library! Most of these activities are named based on the specific grammar concept they cover and the topic they discuss.
Some activities also include a number. If an activity includes a number, that means there are other activities that cover the same grammar concept at the same level. For example, if your students complete Parallel Structure 1 but you feel they need additional practice at that level, you can assign Parallel Structure 2.
Many of our activities cover a specific grammar concept, but some of our activities are categorized as "Advanced Combining" instead. These activities are ones that allow students to combine sentences using any grammatically correct method. Students will receive feedback based on the structure they chose to use.
Open Sentence Combining activities are a great way to give your students opportunities to problem solve and be creative in their sentence construction. Because they provide little direction for students, we recommend having students complete a few activities with a clear grammar target before doing advanced combining activities, especially if they are new to sentence combining.
Our goal is to build strong writers who have made revising an essential part of their writing process. For that reason, we provide students with the opportunity to revise each response up to five times until they have written a strong, grammatically correct sentence. After each revision, students receive feedback that guides them towards a stronger response. If after five revisions the response is still not considered strong, we'll show a few sample responses and ask the student to choose the strongest one before moving on to the next question.
For more on how feedback works for each tool, see this support article.
Students can retry an activity as many times as they want. Once a student has completed an activity, it remains on their dashboard, available to retry at any time.
Quill utilizes a stoplight system of green, yellow, and red scores. A green square indicates that the student scored 76-100%. A yellow square indicates the student scored 50-75%. A red square indicates that the student scored under 50%. A grey square indicates an uncompleted lesson.
Quill follows the guidelines for grammar and style published in the Chicago Manual of Style. While other style guides are geared towards specific audiences and genres of writing, the Chicago Manual of Style is designed to support writers of all types.
Quill provides three diagnostics specifically for ELL students. Directions for each diagnostic are available in Spanish, French, German, Chinese (Simplified), Japanese, Korean, Urdu, Tagalog (Filipino), Vietnamese, Russian, Thai, Ukrainian, Portuguese, Dari (Eastern Farsi), Arabic, and Hindi.
We aim to meet level AA standards from the Web Content Accessibility Guidelines (WCAG) 2.2.
