Compilatio AI Detector

What Compilatio AI Detector is

Compilatio AI Detector estimates the share of a text that may have been generated by AI and marks relevant passages in an analysis report. It checks text associated with ChatGPT, Gemini, Claude, Deepseek, Copilot, and other generative AI systems, across more than 35 languages. Supported files include office documents such as Word files, PDFs, spreadsheets, and presentations, as well as HTML, PHP, and ASP files. Reports can be viewed online or downloaded as PDFs.

The detector is offered through Magister+ for teachers, Studium for students, and 1D345 Copyright for writers. Studium provides a first free partial analysis showing the three most prominent detected sources. Paid Studium bundles range from €4.99, paid once for 20 credits, covering 5,000 words, to €34.99, paid once for 400 credits, covering 100,000 words. Credits can be accumulated and used for six months. Writer packages include 300 pages for €180, paid once and 800 pages for €400, paid once; both prices exclude taxes and remain valid for 12 months. Institutional pricing is on request. Compilatio reports reliability of 94% to 99%, depending on document length, language, and academic content, with fewer than 1% false positives. It advises treating scores cautiously and adding human analysis.
