OpenAI Inc. introduced on Thursday a ChatGPT app for the iPhone, said company chief technology officer Mira Mulrati . She added that an Android version will be available soon. ChatGPT is a software that has quickly gained over 100 million users since its launch last year. The iOS app was the first mobile application to be released for ChatGPT. ChatGPT had previously been available on OpenAI’s site, and through an interface that was used to create third-party applications. Apple Inc.’s (AAPL, +1.37%) App Store hosts apps that use OpenAI software. However, none of these apps are from OpenAI.
