Presentation Authenticity Check
Is the student presenting their material, or reading it from a script? This check helps instructors decide which recorded presentations to review. The video is analysed on the student’s own device and never uploaded.
How it works
Record your presentation the way your instructor asked, then submit it here. It takes a few minutes.
Enter your class code
Type the class code from your instructor and your student number.
Choose your video
Pick the video file from your computer. It is analysed in your browser. Nothing is uploaded.
Submit the results
The measurements are sent to your instructor with one click. You get a confirmation number.
What the check looks for
Reading from a script leaves traces in both the eyes and the voice. The check combines these signals into a reading-likelihood score from 0 to 100, with a timeline showing when they occurred.
Long looks away
Sustained stretches looking down or to one side, where a script or notes would sit.
Line-by-line eye sweeps
Small, steady eye movements across and back, like reading lines of text.
Flat intonation
A voice that stays even instead of rising and falling with meaning.
Evenly timed speech
Unusually regular pace and pauses, typical of reading aloud rather than speaking.
Submit a presentation
You will need your class code, your student number and your video file (.mp4, .mov or .webm). Use Chrome, Edge or Firefox on a laptop or desktop.

Recording requirements
- Put the camera at eye level and keep your whole face in the frame.
- Light your face from the front. Avoid a bright window behind you.
- Record in a quiet room and keep the microphone close.
- Follow your instructor’s rules about notes or cue cards.
For instructors
Each class gets its own code. Submissions appear in a private dashboard on this site.
- Reading likelihood for every video. A score from 0 to 100, the signals behind it, and the reasons a submission was flagged.
- Flagged videos first. Submissions that may be read from a script are listed at the top, so you know which to watch.
- A second-by-second timeline. Jump straight to the moments when the student looked away or their delivery went flat.
- Review notes, class lists and export. Mark videos as reviewed, add private notes, limit codes to your class list, and export to a spreadsheet.
A prompt for review, not evidence of misconduct
The check estimates likelihood from observable signals; it cannot prove that a student read a script. A script placed near the camera lens weakens the gaze signal, and eyewear, camera setup, language background, cultural norms around eye contact, and neurodivergence can all affect results.
Always watch the video before drawing a conclusion. Your professional judgement makes the final call.
Privacy
- The video stays on the student’s device. It is analysed inside the web browser and is never uploaded to this site or anyone else.
- What is sent to the instructor: class code, student number, first name if entered, and the measurements (for example, reading likelihood and time spent looking away). No images, no audio, no recording.
- Who can see it: only instructors and administrators of this site.
- How long it is kept: results are deleted automatically after one year, or sooner if the instructor removes them.
- To track gaze, the browser downloads a face-tracking model from Google’s MediaPipe library. It runs on the device and does not send the video anywhere.
About this research
The Presentation Authenticity Check is an experimental Classerly project. A study is under way comparing its judgements with those of several experienced human raters, to find out how far automated detection can be trusted.
