About Plum

Plum builds personal AI agents that live where your life already happens: your inbox. You give an agent a name, it gets its own email address, and from that moment you work with it the way you'd work with a person - email it a question, cc it into a thread, connect a calendar, ask it to check in every morning.

Two beliefs shape how Plum is built. First, an assistant should accumulate: every conversation adds to a memory and a set of skills that you can open, read, and edit - not a black box. Second, an assistant that can read your mail and calendar must be private by architecture: only people you approve can talk to your agent, your agent can only message people you approve, and every agent runs under a hard daily spend cap. These are enforced in the system itself, not promised in a policy.

Plum is built and operated by Plum Applications, Inc. Questions, feedback, or anything else: email support@plum-app.com.
