> Pulse introduces this future in its simplest form: personalized research and timely updates that appear regularly to keep you informed. Soon, Pulse will be able to connect with more of the apps you use so updates capture a more complete picture of your context. We’re also exploring ways for Pulse to deliver relevant work at the right moments throughout the day, whether it’s a quick check before a meeting, a reminder to revisit a draft, or a resource that appears right when you need it.

This reads to me like OAI is seeking to build an advertising channel into their product stack.
