Check your essay before they do
your draft, your evidence
Teachers run detectors. If your honest writing happens to read “AI” — formal tone, careful grammar, English as your second language — you find out here first, see exactly which lines look machine-written, and fix them before it costs you.
Why honest essays get flagged
Detectors score how predictable your writing is. Careful student writing — even sentences, formal vocabulary, textbook structure — shares that surface with machine text. It is a known bias, not something you did wrong; non-native writers are hit hardest (why ESL gets flagged).
A score is never proof. Every result here shows the specific patterns behind it, so a number turns into something you can actually check — and fix.
Three honest uses
- Pre-submission check. Paste your essay, see the score a detector would give it, and the exact lines pushing it up. Fix them — they're marked in your text.
- Make AI-assisted work yours. If your course allows AI for drafting, this shows what still reads machine-written so the final version genuinely carries your voice.
- Evidence if you're accused. Falsely flagged? Scan your own draft history, export the PDF report, and bring evidence to the conversation instead of just your word.
Not an evasion tool. We won't help you disguise work that isn't yours — and tools that promise “undetectable” are selling you a moving target. Honest rewriting is the only fix that lasts.
If you're accused and it's wrong
- Keep your drafts. Version history, notes and research trails show process — the strongest evidence you can bring.
- Bring the breakdown, not just a “no.” A per-line report turns “the tool says AI” into “here are the exact lines and why they fired.”
- Ask about the detector. Which one was used, and its known false-positive rate — especially for non-native writers. A lone score isn't dispositive, and most institutions know it.
Private by design. Anonymous scans are never stored — your school can't see them because there is nothing to see. Scans saved to a free account are private to you and deletable any time.
Free and anonymous — see what a detector would say about your essay, line by line, before anyone else runs one.

Why does my own writing score high?
Formal, careful writing — especially from non-native English speakers — shares surface habits with AI text: even sentences, formal vocabulary, few contractions. That's exactly why we show the reasons, not just a number, and why no score should ever be treated as proof.
What should I do if I'm accused of using AI?
Stay calm and bring evidence: your draft history, notes, and a ScanForAI report showing the per-line breakdown. Ask what tool was used and its known false-positive behavior. A single detector score is not proof, and most institutions know it.
Is it free for students?
Yes — the scanner is free and anonymous, and a free account adds the full pattern breakdown, deep analysis, history and PDF reports. No card.
If I scan my essay here, can my school see it?
No. Anonymous scans are never stored — there is nothing to see. Scans saved to a free account are private to you and deletable any time. We don't report to institutions, full stop.
Can universities detect AI writing?
Most run something — Turnitin's AI indicator or a standalone detector — and every one of them has documented false positives. That's the practical reason to check your own work first and keep your drafts: you want evidence on your side before anyone else runs a tool.
How do I make allowed AI use safe to submit?
Three steps: follow your course's citation rule for AI assistance, rewrite the draft until it genuinely carries your voice, then scan it — the marked lines show exactly what still reads machine-written. If the marks are gone, the writing is yours in the way that matters.
