A taste of a lesson

One question and the answer, as this tutor gives it.

Can you detect AI writing? The honest answer AI tutor following Bruno Azevedo's plan
Student:

A detector said my essay is 80% AI, but I wrote every word. What do I do?

Tutor:

Stay calm; detectors are known to flag human writing, especially clear, structured or non native writing. Gather your process evidence: drafts, notes, browser history of your research, and version history if you wrote in a document editor that keeps it. Ask for a meeting and offer to talk through your argument and how you developed it. Check your institution's policy on how detector results may be used; many say they cannot be the sole evidence. Which of those evidence types do you already have?

Written by the teacher as an example. In your lesson the tutor answers your own questions, and like any AI it can be wrong.

What you will be able to do

  • Explain how AI text detectors work and why they make errors
  • Describe who is most at risk of false accusations and why
  • Explain what watermarking can and cannot do
  • Handle suspected AI use with process evidence, fair conversations and clear policy

About this tutor

For teachers, students, editors, hiring managers and anyone asked 'was this written by AI?'. You learn how AI text detectors work, why they produce false positives and negatives, why some writers, including non native English speakers, are flagged more often, and why human 'gut feel' detection is also weak. You look at watermarking proposals and their limits. Then you focus on fairer approaches: process evidence such as drafts and version history, conversations about the work, clear policies on acceptable AI use, and assignment or task design that makes the question matter less. You finish able to respond to suspected AI use without unfair accusations.

    I was falsely flagged. The advice on version history and the meeting script helped me clear my name.

  • Callum J.Sample

    Clear and fair. The policy drafting at the end was useful. Watermark section could be a little more detailed.

  • Esther L.Sample

    As a teacher I needed this. The point about small error rates becoming many false accusations changed my department's approach.

  • Laila B.Sample

    Good balance between protecting writers and taking teachers' concerns seriously. Short and to the point.

I teach people to judge AI claims, spot synthetic media and report on AI without the hype

I teach media literacy for the age of AI. My learners include journalists, students, sceptics and anyone tired of breathless headlines in both directions. We practise reading claims about AI critically, checking images and video, understanding why AI text detectors fail, and asking the questions a careful reporter would ask. My background is in newsroom fact checking and training reporters,...
