Are AI detectors biased against non-native English speakers?

There are instances where an AI detector may incorrectly list a non-native speaker's written materials as being generated by artificial intelligence (AI) due to the writer’s use of formal language, repetitive text or simplification of grammar. Additionally, most artificial intelligence-generated text includes all of the traits of the typical learner's writing to acquire their academic language skills. Although the above does not imply that non-native writing has been generated using an AI system, it does illustrate that all detections are not necessarily definitive proof of being the product of an AI system.
Modern tools like Quetext’s AI Detector are designed to reduce this risk by analyzing broader linguistic patterns instead of relying on a single signal. A combination of human and computer reviews, as well as context and transparent writing methods, will create an effective means of detecting AI-created works. Writers can use personal experiences and/or examples to increase their originality, as well as put some natural variation into the tone of their writing and/or the structure of their sentences.
