AIscan24

AIscan24 is an AI text detector built by German entrepreneur Gabriel Morgenstern (GabloMo) for teachers, editors, agencies and developers: paste at least 80 words, press "Check Text" and within seconds you get a score showing how closely the text resembles content generated by models such as ChatGPT, Gemini or Claude.

What is AIscan24 and how does it detect AI writing?

The scanner looks for statistical patterns typical of large language models: repetition, filler words, stock phrases and formatting that models use far more than people do. Rather than claiming an exact probability, it reports AI similarity and suggests how to read it:

• Under 33%: likely human.
• Around 50%: rewritten or mixed.
• Over 66%: likely generated or AI-assisted.

How accurate is the AIscan24 AI detector?

The site openly says no detector can prove AI use: generated text carries no watermark and human and machine language overlap heavily. Its analysis is therefore conservative to avoid false positives, and it suggests asking for a document's edit history when in doubt. Longer texts give more accurate estimates.

Does AIscan24 have an AI detection API?

Yes. The AIscan24 API takes a simple cURL call with an API key, usually responds in under a second, returns a 0–100% score and is hosted in the EU under GDPR. You can request a test key before asking for a quote.

AIscan24 pros and cons

Pros: no account or email required, texts are never stored or used for training, and processing runs on German servers. Cons: it needs at least 80 words, gives only an overall estimate with no sentence-level report, and the site does not state its accuracy on non-English text.
