Description
Korrektur.de is a German editing and proofreading service that also runs a dedicated AI-detection tool for students who want to check a paper before they submit it. The page explains how German universities screen for AI-generated writing and lets a student run the same kind of check on their own thesis, essay or seminar paper first.

The detector analyzes a submitted document sentence by sentence, looking for the statistical patterns, perplexity and burstiness, that many university systems such as Turnitin, Copyleaks, iThenticate and PlagScan also rely on. Flagged passages are color-coded so a student can see exactly which sentences read as machine-generated rather than getting only a single overall percentage.
Results come back by email, typically within 24 hours (Korrektur.de advertises delivery in as little as 30 minutes), and the report explains what the score does and does not prove: a percentage above zero is not automatic proof of AI use, since quotations, a bibliography or a very uniform writing style can also raise it. Checking a document costs from 0.29 euros per standard page (250 words), so a 50-page bachelor's thesis runs to roughly 14.50 euros; a combined AI-and-plagiarism scan is priced at 0.39 euros per page instead of paying for both separately. Uploads are processed anonymously in Germany under GDPR, are never shared with a university, and are deleted automatically after seven days.
The tool is aimed at students at German-speaking universities who want to catch a possible false flag before their supervisor does, particularly for bachelor's and master's theses, seminar papers and other coursework. Korrektur.de is upfront that no detector, including its own, identifies AI-written text from ChatGPT, Claude or Gemini with certainty in every case, and that its score is not directly comparable to what a university's own software would produce, since providers use different models, thresholds and supported languages. For a text flagged as suspicious, Korrektur.de also offers a separate proofreading and editing service to revise the writing style.
