Free AI Text Detector by QuizFlex: What It Measures (Without Uploading Anything)

Teachers and writers often need a fast way to estimate whether pasted text resembles typical AI output - for classroom discussions, drafts, or research integrity talks. QuizFlex’s AI Text Detector is a free, no-login helper that scores text using transparent heuristics (including burstiness, lexical diversity, and common phrase patterns) - all in your browser.

How to use it (30 seconds)

1. Open AI Text Detector.
2. Paste the passage you’re reviewing - nothing is uploaded; processing stays client-side where possible by design for privacy.
3. Read the concise summary and cues: use it as a conversation starter, not a courtroom verdict - no detector is definitive.

What it is - and isn’t

• Transparent heuristics - you get an explained scoreboard-style readout, not a black box verdict.
• Not proof of cheating - always pair dialogue and context rather than punitive snap judgments.
• Works best on longer excerpts - very short snippets give noisy signals across any detector-like tool.

When it helps classrooms

Discuss how AI writing feels (uniform tone, templated pacing) vs thoughtful student voice. Invite students to revise for specificity and citations - skills that transcend any particular tool.
