Now you (and your coding agents) can write code to sync any data and build any agent tool, all running on our infrastructure. You can also bring your favorite agents into Notion (like Claude, Codex, Decagon, or ones you’ve built yourself). It turns Notion into one shared canvas with all your data, for your team and agents to work together.

The result is fewer surprises and more confidence in complex, multi-step work.
