👋 Educators, AI Writing Check is a free service developed by Quill.org and CommonLit.org to enable educators to check if a piece of writing submitted by a student was written by the AI tool ChatGPT. This algorithm is designed to detect AI-generated writing.

We estimate, based on testing with 15k essays, that this tool is accurate 80-90% of the time. For this reason, we'd like to encourage teachers to exercise caution when using this tool to detect academic dishonesty. AI Writing Check is a stopgap tool measure for educators to use this school year until more advanced AI detection tools are made widely available.

To check responses longer than 400 words, you must separate the text into individual sections.

This free tool has no guaranteed uptime or support. It may not be available when there is heavy demand.

Processing

Your submission is in the queue. The system processes one text every two seconds, meaning that it can take minutes when there is heavy demand.

Three Important Things to Know

This tool is not perfectly accurate - it will misidentify some pieces of writing

No tool AI text detection tool is perfectly accurate. This tool is accurate about 80% to 90% of the time, meaning that one or two of every ten pieces of writing that were flagged as human written will actually be written by AI.

Warning Gate
Students can fool the system by rewriting the text

Students can fool algorithms that identify AI writing by rewriting the bot’s writing or by using another AI tool to rewrite the text for them. If a student sufficiently changes the writing, it is difficult for an AI tool to detect it as AI writing.

Chat Message
When you identify AI generated writing, treat this as a learning opportunity

Students are curious about AI, and we should encourage students to learn how to use these tools. If a student has misrepresented AI writing as their own, we have created a toolkit that may help you talk to your student about why it is that students cite their sources and not misrepresent someone else’s work at their own.

Warning Gate
This tool is not sufficient proof of academic dishonesty

The AI detection algorithms look for formulaic patterns. Since students sometimes write in a formulaic style, all AI detection algorithm will sometimes mistakenly flag this writing as AI writing. No AI tool is accurate enough to be definitive proof of academic dishonesty.

Educators, we created a toolkit to help you talk about AI plagiarism with your students

With the introduction of this new technology, students are curious about how to use it. We believe that if students use AI tools as research tools, and properly cite it as a source, it can help students learn about new ideas. However, when students pass off AI generated writing as their own, they are not engaging in the critical process of building their own writing skills. To help you set the right expectations with your students and navigate these conversations, we created a toolkit.

We created AI Writing Check to support strong writing education for students

Quill.org & CommonLit are nonprofit educational technology organizations dedicated to helping 3rd - 12th grade students become stronger writers. Quill.org provides writing activities that use AI to provide students with immediate feedback and coaching, enabling them to continually revise their work and build their skills. CommonLit provides interactive reading and writing activities, and a full English Language Arts curriculum to support literacy development in grades 6-12.

Quill.org and CommonLit deeply believe that every student needs to be a strong writer to succeed in school and careers, and technology can help build these writing skills. To achieve this mission, both of our nonprofits provided our activities for free to all educators and students.
