AI Detection in Your LMS: Canvas, Moodle and Google Classroom Compared
Which AI detectors integrate natively with Canvas, Moodle, Google Classroom and other LMS platforms in 2026, what LTI 1.3 actually is, why Google Classrooms originality reports do not detect AI, and the integration problems schools only discover after buying.
If detection lives in a separate tab, teachers stop using it inside a term. That is the strongest argument for wiring AI detection into your LMS, and it is why "does it integrate with Canvas" is usually the second question in any school procurement conversation, right after price.
This guide covers who actually integrates with what in 2026, what the integrations really do, and the problems schools tend to discover only after they have bought.
Who integrates with what
Sources: Turnitin's LTI 1.3 integration list, Copyleaks LMS page, GPTZero LMS integrations, Pangram for teachers.
Three honest notes on that table. First, "integrates" means different things: Turnitin puts an AI score inside its Similarity Report, which the instructor must open, while Copyleaks builds AI detection into every LMS integration and shows a High/Medium/Low indicator with suspected text highlighted. Second, GPTZero's broader LMS coverage runs through a partnership with K16 Solutions rather than native connectors, and it scans final submissions only, not drafts. Third, we are in that table with three noes: Is It AI? has no LMS integration yet, and we would rather say so plainly than imply otherwise.
What LTI 1.3 actually is
Learning Tools Interoperability is a standard from 1EdTech, formerly IMS Global, that lets an LMS plug in an external tool so it appears inside the course: students submit as normal, the tool processes the work, and results come back without anyone managing a separate login. LTI 1.3 is the current version, and the practical difference from the older standard is security, using OpenID Connect and signed tokens for everything passing between the LMS and the tool.
Why you should care at procurement time: if a vendor claims LMS integration, ask whether it is LTI 1.3, a plugin, or a browser extension pretending to be an integration. LTI 1.3 is the one your IT team can deploy and control centrally.
Google Classroom is the special case
Classroom dominates UK state schools, where it is effectively free inside Google Workspace for Education, with Microsoft Teams the main alternative in Microsoft schools. In the US, Classroom holds roughly 31% of K-12, with Canvas around 24% and Schoology around 19%.
The thing many schools get wrong: Google Classroom's built-in originality reports do not detect AI. They are a plagiarism tool, comparing work against web pages, books and, on paid Education plans, other student submissions in the district. An essay written from scratch by ChatGPT contains no copied text, so it sails through with no flag. If your school's AI policy assumes Classroom is checking for AI, it is checking for something else.
Turnitin: on by default, and an add-on
Two facts about the incumbent that surprise schools. AI detection is enabled by default where licensed, controlled at the institutional admin level, so individual teachers may be generating AI scores without the school ever making an active decision to switch them on. And it is not part of base Turnitin: the AI detector ships only with the Originality licence, a paid uplift on the Similarity contract most schools already hold. Pricing is quote-based throughout; there is no public price list.
It is also worth knowing that a run of well-known universities, including Vanderbilt and several others, have switched Turnitin's AI detection off entirely, citing false-positive risk. Integration convenience and institutional confidence are not the same thing.
The problems schools report after integrating
We hear four recurring complaints, and they are worth designing around before you buy rather than after.
- The student cannot see the report. In most LMS workflows the AI score is instructor-facing only. The student being asked to explain their essay has never seen what was flagged. That asymmetry undermines fair process, and it is the single best argument for pairing any tool with a policy of showing students the flagged passages.
- False positives arrive at volume. Even a genuinely low false-positive rate produces a steady stream of wrongly flagged essays across a school year of submissions, each one a dispute, a review and sometimes a parent call. Our published benchmark explains why the false-positive rate, not the accuracy headline, is the number to interrogate.
- A score with no reasons. Most integrated reports give a percentage and a highlight, not an explanation a teacher can weigh or a head of department can defend in an appeal.
- Auto-scanning changes the relationship. When every submission is scanned by default, teachers are no longer choosing to check a piece of work; the system is monitoring everyone's. Some schools want that; many discover they do not.
Where Is It AI? fits, honestly
We do not have an LMS integration today. Detection runs in the browser: a teacher pastes text and gets flagged passages with plain-English reasons, and submitted text is never stored, which keeps the GDPR review short. For a department doing judgment-led spot checks that workflow holds up well; for a school that wants every Canvas submission auto-scanned, we are not the right tool yet, and Turnitin or Copyleaks are the credible options.
If you are choosing for a school, our schools comparison covers the institutional criteria beyond integration, and the false-positive benchmark covers the number that should drive the decision.
Frequently asked questions
Which AI detectors integrate natively with Canvas?
Turnitin (via LTI 1.3, with the AI score inside the Similarity Report), Copyleaks (LTI 1.3, with AI detection built into the integration), GPTZero (a native Canvas integration, plus institution-scale coverage through its K16 Solutions partnership) and Pangram (which shows its score in the grading workflow). Originality.ai has no native LMS integration and Winston AI connects to Google Classroom but not Canvas.
Does Google Classroom have built-in AI detection?
No. Google Classroom's originality reports compare student work against web pages and books for plagiarism, and on paid Education plans against other student submissions in the district. They do not flag AI-generated text: an essay written from scratch by ChatGPT gets no originality flag. Schools that want AI detection inside Classroom need a third-party integration such as Copyleaks, GPTZero, Pangram or Turnitin via Assignments.
What is LTI 1.3?
Learning Tools Interoperability is the 1EdTech standard that lets an LMS such as Canvas or Moodle plug in an external tool so it appears inside the course without a separate login. LTI 1.3 is the current secure version, using OpenID Connect and signed tokens to pass submissions and grades between the LMS and the tool. When a detector advertises a native Canvas or Moodle integration, LTI 1.3 is usually the mechanism underneath.
Is Turnitin AI detection switched on by default?
Yes, where the institution licenses it. Turnitin's AI writing detection is enabled by default and controlled from the institutional admin account, which can switch it off globally or per sub-account. It is also a paid add-on: AI detection ships with the Originality licence rather than base Turnitin Similarity, so it is an uplift on the existing contract, and several universities have chosen to turn it off entirely.
Can students see the AI report in LMS-integrated detection?
Usually not. In typical LMS workflows the AI score is visible to the instructor inside the similarity or grading report, while the student never sees what was flagged or why. That asymmetry makes appeals harder and is one of the most common complaints schools raise. Whatever tool you use, pair it with a policy that shows the student the flagged passages before any conversation about consequences.
