Häufig Gestellte Fragen

What is the most accurate AI content detector right now?

GPTZero and Originality AI are generally seen as the most accurate. They update models quickly to detect new patterns from generative AI tools. They offer high confidence scores.

Do free AI detection tools work well?

Many free version tools offer basic checks and a limited word count. They can catch simple AI-generated content. For serious or high-volume work, a paid plan or pro version is much more reliable.

Can I use a paraphraser to bypass AI detection?

Paraphrasing tools like QuillBot can make AI-generated text sound more human-like. However, the best AI detection tools can still flag the underlying sentence structure and patterns of AI use.

Should I use more than one AI content checker?

Yes, it is smart to use other tools, such as a second detector. No single AI content detector is 100% perfect. Using two or more sources gives you a much higher confidence level in the content’s originality.

Is there a good AI detector browser extension?

Yes, many top tools offer a convenient Chrome extension. This lets you quickly analyze text right in your browser or in Google Docs without copying and pasting it into an input box.
