Does Canvas detect AI writing?

Canvas

Canvas, from Instructure, does not include its own AI writing detector. AI checks reach Canvas through tools a school connects, usually by LTI or the plagiarism framework. The common ones:

• Turnitin. Schools that license Turnitin Feedback Studio usually connect it for similarity checks, and its AI writing indicator appears in the same report.
• Copyleaks. Lists Canvas among its LMS integrations, with AI detection included.
• GPTZero. Lists Canvas and Google Classroom on its LMS integrations page; LMS integration is part of its Professional plan.
• Grammarly Authorship. Integrated with Canvas on September 25, 2025. It is not a detector: students write with Grammarly running and share a report of what was typed, pasted or generated.

So when a student asks “does Canvas detect AI,” the accurate answer is that Canvas shows whatever the school connected. If you are not sure what your school uses, your Canvas administrator or teaching center can tell you.

Google Classroom

Google Classroom’s originality reports compare a student’s Docs, Slides and Word files against webpages and books on the internet, and against past submissions at the same school if an administrator turns that on. Google’s help page describes matching, not AI detection. On the free Education Fundamentals edition, teachers can run originality reports on 5 assignments per class; beyond that needs the Teaching and Learning add-on or Education Plus. The Gemini features Google added to Classroom in 2026 help teachers write feedback; we found no AI detection feature announced.

Schoology

Schoology, from PowerSchool, connects Turnitin as an LTI tool for originality reports and grading. We found no PowerSchool statement about a built-in AI detector. As with Canvas, an AI score in Schoology comes from a connected tool, and Copyleaks also lists Schoology among its integrations.

What a connected detector can and cannot tell you

Whichever tool shows up inside your LMS, a detector reads the finished text and estimates whether it resembles machine output. Turnitin’s own guide says its score “should not be used as the sole basis for adverse actions against a student,” and independent research has found much higher error rates for some writers than vendors report. The Turnitin accuracy page and the false positive rates table have the numbers.

What a detector cannot show is how the essay was written: what was typed, what was pasted, and how the draft changed. That is a different kind of evidence, and it holds up better when a student disputes a result.

When students ask whether Canvas can see their AI use

Students search this question too, and the honest answer helps everyone. Tell them what your course actually checks: which tool, if any, scores submissions, and whether the essay is written somewhere the process is recorded. Students who know how work is checked spend less energy guessing and more on the essay. Be precise about what a detector does: it reads the submitted text after the fact. It does not watch a student write, and it cannot say how the essay was produced.

What to do next

1. Find out which tools your school has connected to your LMS.
2. Read what that tool says about how its score should be used, and your school’s policy on it.
3. For essays that matter, set things up so there is a record of how the essay was written, not only a score on the result.
4. When a score raises a question, follow the step by step guide before contacting the student.

Using EssayGuard alongside your LMS

EssayGuard is a writing editor that records the session, and it works next to any LMS. Create the assignment in EssayGuard in about three minutes and post its link in Canvas, Google Classroom, Schoology, Blackboard or Moodle the way you post any link. It opens in its own tab; students sign in with a school account or an email and write, with nothing to install. Every keystroke, revision, pause and paste is recorded with server-side timestamps.

Each essay comes back marked Approved, Needs Review or Flagged, with a replay and a plain summary of what the recording shows. EssayGuard gives no AI percentage, and every decision stays with you. It is free for the rest of this semester; set up an assignment and post the link in your course today.

A record has a limit worth stating: it shows how text entered the editor, not whose ideas it carries. It gives a conversation with the student something concrete to start from.
