KI-Detektoren
Prüfen Sie, ob ein Text, ein Lebenslauf oder ein Bild mit KI erstellt wurde, finden Sie erfundene Quellen in Chatbot-Antworten und vergleichen Sie Dokumente auf kopierte oder umformulierte Passagen. Kostenlos und privat: Die Analyse läuft in Ihrem Browser.

How these detectors work, and their limits
The AI Detector and the AI CV Detector run an open RoBERTa classifier trained on the RAID benchmark, which covers text from many large language models, including texts rewritten to evade detection. The model is downloaded once (about 126 MB) and then runs inside your browser, so the text you check is never sent to us or to anyone else. It scores the text passage by passage, which is why you see highlighted sections rather than a single verdict.
No AI detector is proof. Short texts, lists, formulaic writing (legal, technical, recipes) and writing by non-native speakers produce more false positives, and lightly edited AI text can pass as human. Treat a high score as a reason to look closer, ask questions or check drafts and version history, never as the only evidence against a person.
The AI Image Detector relies first on provenance: Content Credentials (C2PA), the IPTC "trained algorithmic media" label and the generator names that tools such as ChatGPT, Adobe Firefly, Midjourney and Stable Diffusion write into files. When that metadata has been stripped, it falls back to two small visual classifiers, which are much less reliable on the newest generators.
The AI Hallucination Checker looks up every link, DOI, arXiv ID, ISBN and reference in a chatbot answer, then lists the statistics, dates and quotes you should verify yourself. The Plagiarism Checker compares a text with sources you provide and highlights identical wording and paraphrased sentences; it does not search the web.

Häufig gestellte Fragen
How accurate are AI detectors?
No AI detector is 100% accurate. Treat the score as a signal to look closer, read the highlighted sentences and never rely on it alone.
Is my text sent to an AI service?
No. The analysis runs in your browser; your text is not sent to ChatGPT or any other AI service.
Which AI models can be detected?
The text detector looks for patterns typical of ChatGPT, Gemini, Claude and similar models; the image detector reads AI labels and metadata.
