Artificial intelligence research startup OpenAI on Tuesday introduced a tool that’s designed to figure out if text is human-generated or written by a computer. The release comes two months after OpenAI captured the public’s attention when it introduced ChatGPT, a chatbot that generates text that might seem to have been written by a person in response to a person’s prompt. Following the wave of attention, last week Microsoft announced a multibillion-dollar investment in OpenAI and said it would incorporate the startup’s AI models into its products for consumers and businesses.
