Introducing ChatGPT Pulse
Today we’re releasing a preview of ChatGPT Pulse to Pro users—a new experience where ChatGPT proactively does research to deliver personalized updates based on your chats, feedback, and connected apps. Each night ChatGPT learns what matters to you—pulling from memory, chats, and feedback—then delivers focused updates the next day. Expand updates to dive deeper, grab next steps, or save for later so you stay on track with clear, timely info. Pulse is the first step toward a more useful ChatGPT that proactively works on your behalf, and this preview lets us work with power users to learn, iterate, and improve before rolling it out more broadly.
Keep thinking with Claude
There's never been a better time to be a problem solver. Claude is the AI collaborator that helps you think deeper—whether you're coding, creating, or reimagining what’s possible. Keep thinking. https://claude.com
