AI Detector Limitations

Many tools have limited resources and only allow a particular number of words to be tested or require login to restrict the number of users and prevent bots from gaming this, and many have paid versions that will enable more automated queries and analyze higher numbers of queries easily.

Since these models are mostly trained in English, it is very possible that non-English text will be wrongly interpreted. Moreover, many tools will require 500-1000 words minimum to correctly assess the content for AI writing. Many people are now using these AI detectors to keep editing the AI-written text and retesting it till it appears more human-written!

AI generated art is another popular buzz area and AI art detection tools may be out next.
