AI Detector for Teachers — Verify Student Work

Check student essays for signs of AI generation and copied text. You get a probability score and sentence highlights to discuss with the student — never proof on their own.

Using AI Detection Responsibly

AI detectors can be wrong, including on genuine student work. Used carefully, a score and its highlighted sentences can start a conversation; used alone, they can lead to unfair accusations.

Sentence-Level Transparency

The result highlights the sentences that drove the score, so you can talk with a student about specific passages instead of a single number.

Combined Academic Integrity Tools

Check both AI generation and plagiarism in one platform. Since student work can be original but AI-written, or human-written but copied, having both checks available streamlines your review process.

Confidence Scoring, Not Binary Judgments

Results are probability scores, not verdicts. Treat them as one signal that needs context — drafts, revision history and a conversation — before any decision.

How to Review a Submission

  1. 1

    Upload Student Submission

    Copy the student’s essay text or upload their document file to the detector for analysis.

  2. 2

    Review Confidence Score

    Check the overall AI-likelihood score. A higher score is a reason to look more closely, never a conclusion on its own.

  3. 3

    Examine Sentence-Level Flags

    See which sentences contributed to the score. Use them as conversation starters, not as evidence of misconduct.

  4. 4

    Check for Plagiarism

    Run the plagiarism checker to see if the work copies existing sources, which is a separate issue from AI generation.

  5. 5

    Have a Conversation

    Share the results with the student and ask about their writing process. Request drafts or revision history to understand how the work developed.

Benefits for Educators

  • Specific Passages to Discuss

    Sentence highlights give you concrete passages to ask about. They are not evidence of misconduct on their own.

  • Free Scans to Start

    3 free scans in total, shared across all tools, with no signup needed to start.

  • Teaching Opportunity

    Use the tool in class to show how AI detection works and why its results can be wrong.

  • Supports Fair Policies

    Probability scores make the uncertainty visible, which supports policies that never rely on a detector alone.

  • Integrated Workflow

    Check AI detection, plagiarism, and grammar without switching platforms — saves time during grading.

Frequently asked questions

Best Practices for Using AI Detection in Education

  • •Include AI detection policies in your syllabus and discuss them transparently with students
  • •Treat detection results as conversation starters, not automatic penalties
  • •Request additional evidence (drafts, revision history) when scores are high
  • •Consider student background — non-native speakers may be falsely flagged
  • •Focus on teaching authentic writing rather than just catching AI use
  • •Document your process and maintain consistent standards across all students
