We Interviewed The Team Behind OpenAI's #1 Feature

OpenAI’s personalization leads, Christina Kaplan and Samir Ahmed map the shift from an “assistant with a notebook” to Pulse—the part of ChatGPT that quietly preps your day while you sleep. We unpack how short- and long-term memory work across sessions and why April’s subtle update changed the experience, show how daytime chats stay aligned with overnight prep, and close on the big questions: privacy, consent, and why this is an assistant/representative—not a digital clone.
