AI Detection.
Edexia detects AI-generated student writing through process analysis, not just output scanning. By recording the full writing process and analyzing behavioural signals, Edexia identifies AI use with fewer false positives than tools that rely on statistical text patterns alone.
Writing Replay
Edexia records how each essay was written, keystroke by keystroke. Teachers can replay the entire writing session and see exactly how the text took shape. This means you can see whether a student wrote, revised, and rethought their arguments, or whether large blocks of text appeared all at once. Writing replay turns academic integrity from guesswork into evidence.
AI Likelihood Scoring
Edexia assigns an AI likelihood score to each submission based on behavioural signals. These signals include typing speed patterns, pause intervals, revision behaviour, and structural consistency. The score gives teachers a quick summary alongside the detailed replay. It is a starting point for a conversation, not an automatic verdict.
Paste Detection and Tab Tracking
The system flags when text is pasted into the editor and when the student switches away from the writing tab. These are not proof of misconduct on their own, but combined with the writing replay and AI score, they give teachers a complete picture of how the essay was produced.
Why Process Beats Output Scanning
Output-based detectors like GPTZero and Turnitin's AI detection work by analyzing the finished text for statistical patterns that suggest AI authorship. The problem: these tools produce significant false positives, especially for ESL students and formulaic writing styles. They also become less reliable as AI models improve.
Process-based detection takes a different approach. Instead of asking "does this text look like AI wrote it?", it asks "how was this text produced?" That question has a clearer answer and does not penalize students for writing clearly or formally.
Edexia's detection tools are designed to support honest conversations between teachers and students, not to generate accusations. Teachers see the evidence and decide how to use it. The goal is to maintain trust in the classroom while giving teachers the information they need.
