AI Text Classifier
ExternalThe OpenAI AI Text Classifier was a free web tool launched in January 2023 to detect AI-generated text, providing labels from 'very unlikely' to 'likely AI-generated' for inputs over 1,000 characters. Trained on diverse human English text and outputs from 34 AI models across five organizations, it offered a simple way for users to assess text authenticity amid rising AI content creation. Though innovative, it was discontinued in July 2023 due to low accuracy, marking an early but imperfect step in AI detection technology.
