OpenAI launches ChatGPT Pulse

OpenAI launched ChatGPT Pulse, a feature that has the model research and prepare a set of personalised briefs overnight rather than waiting for a user to ask a question. Each morning, Pulse presents roughly five to ten items — drawn from a user’s chat history, saved memory, and optional connections to apps such as Gmail and Google Calendar — covering things like calendar-relevant reminders, news relevant to a user’s stated interests, and suggestions based on past conversations.

Sam Altman announced the feature on X, framing it as a shift from ChatGPT as a tool that responds to prompts toward one that does work in the background and surfaces it proactively. The launch was limited to Pro subscribers on iOS and Android, in preview form; OpenAI said it planned to bring the feature to other subscription tiers once it had found ways to run the overnight generation more efficiently, an indication that the compute cost of researching and drafting briefs for every user each night was a constraint on wider rollout.

Pulse extended a direction OpenAI had already been moving in with ChatGPT’s memory and connector features, and situated the product alongside a broader industry push — visible also in rivals’ own assistant features — toward AI systems that act on a standing understanding of a user’s context rather than starting fresh with each conversation.
