From my experience with AI or Not, I found it excels at providing a quick and accessible way to check if text is AI-generated without any cost or sign-up barriers. The straightforward interface makes it ideal for educators and editors who need fast verification. However, the tool currently supports only English and lacks integration options, which may limit its use in more complex workflows. Overall, if you need a free, no-frills AI content detector for basic authenticity checks, AI or Not delivers reliable and user-friendly results.
