University instructors are increasingly aware of AI writing patterns — and they know exactly where to look. Here are the most common signals they check.
AI models like ChatGPT produce text with recognizable patterns: unusually uniform sentence structure, overly smooth transitions between paragraphs, and — paradoxically — a tendency toward polished vagueness. The text sounds competent but rarely commits to a specific argument.
In English academic writing, instructors are particularly alert to a lack of personal voice. Strong essays have a perspective; AI-generated text tends to present "both sides" without taking a clear stance.
PaperScan's detection model for English texts has been specifically trained on English academic papers — essays, term papers, and research papers. It understands the conventions of English academic style and identifies deviations that suggest AI authorship.

Yes. PaperScan uses a dedicated detection pipeline for English academic texts, separate from the German model. It has been specifically calibrated for the conventions of English essay and term paper writing — including how English AI text differs stylistically from human academic prose.
The Standard plan covers essays and term papers up to 100 pages — sufficient for most undergraduate and postgraduate assignments. For longer papers (dissertations, theses), see our thesis page or choose the Premium plan (up to 250 pages).
For a typical essay (5–20 pages): approx. 1–3 minutes. For longer term papers (20–50 pages): approx. 2–5 minutes. You receive a direct link to your report after payment — the page doesn't need to stay open.
Partially. PaperScan analyzes stylistic patterns, sentence structure, and argumentation depth — not just word matches. Heavily reworked text will score lower, which is appropriate: if you've genuinely transformed AI output into your own work, that counts as independent writing.
Yes. Your file is automatically deleted after analysis and stays on the server for a maximum of 24 hours. No account required, no personal data stored. Server location: Germany. Fully GDPR-compliant.
The Standard report includes: overall AI score (0–100) with rating, detected usage pattern, chapter-by-chapter score breakdown, the most suspicious passages with direct quotes and reasoning, concrete rephrasing suggestions, and a grammar & spelling check.
