A quiet, private journal that listens back.

Plimm is a journaling app for iPhone and Android. You write. An AI that lives entirely on your phone reads with you, notices patterns over time, and talks with you about what you wrote.

Your words never leave your device. There are no accounts, no cloud, and no server that stores your journal. We could not read your entries if we wanted to.

Plimm is not therapy. If you are in crisis, please see our crisis resources.
