Apple Core

Use Apple Notes with your AI client

Apple Core is a native macOS app that connects compatible AI clients to Apple Notes through the Model Context Protocol, or MCP. Enable Notes in Apple Core, grant the required permissions and connect your client using the setup guide.

Release status: Apple Core 3.0 is in prerelease testing. The expanded Notes features below are part of that preview, not the current public download. See the release notes for the current release.

Use your client to find notes, read their contents and work with folders. A useful request names the subject and folder, such as “Find the project meeting notes in my Work folder.” Review the selected note before asking your client to change it.

Expanded Notes tools in the 3.0 preview

The preview adds ways to work with Notes' native objects, alongside text and attachments:

Permissions and compatibility

Apple Core requires macOS 15.1 or later. Advanced Notes actions have additional compatibility requirements and need Full Disk Access. Apple Core checks the capabilities required by each action and reports when your Mac cannot perform it.

Your Mac must be awake and running Apple Core while a client uses its tools. Some Notes actions also need an active desktop session. Enabling Notes gives authorized clients access to its available tools, including actions that change data.

Local changes and iCloud sync

A successful local write does not confirm that iCloud has uploaded the change. The preview reports pending synchronization separately. Check the result on another device before relying on its availability there.

Choose what your client can access

Turn Notes access on or off in Apple Core Settings. Your AI provider receives the information returned by the tools you use. Review the privacy policy for local access, hosted forwarding and account information.

Start with the Notes preview guidance, read the release notes, or visit support if a command cannot access your notes.
