According to Sam Altman (@sama), OpenAI has launched a new ChatGPT feature called Pulse, initially available for Pro subscribers. Pulse continuously analyzes user interests, connected data, and recent chats overnight to deliver personalized recommendations each morning. This AI-driven feature enhances user engagement by proactively providing tailored updates, moving ChatGPT from a reactive tool to a proactive, highly personalized digital assistant. The feature demonstrates a significant trend toward hyper-personalization in AI, creating new business opportunities for advanced AI-powered personal assistant services.
