Local AI for Mac, iPhone and iPad

Your Mac runs the AI. Your iPhone asks the questions.

CereVault Serve runs open models on your Mac with Apple MLX. CereVault is the chat app for Mac, iPad, iPhone and Vision Pro that talks to it. Your chats stay on your device, and nothing leaves unless you ask it to.

The stack

One private AI setup across your Apple devices.

Serve runs the models on your Mac. CereVault is where you use them. Already on Ollama or LM Studio? CereVault works with those too.

Made to fit together

Turn on sharing in Serve and your Mac shows up in CereVault on your iPhone and iPad. No IP addresses to type. Add an access code if you like.

Your Mac's models on your phone

Most local AI apps stop at the Mac. CereVault runs the models on your Mac from your iPhone and iPad, over your own Wi-Fi.

Agent tools, no cloud account

Web search with no API key, files in folders you choose, MCP servers, workspaces and automations. Every third-party tool call asks first.

It stops before data leaves

A privacy check spots emails, phone numbers, card numbers and API keys in a search or tool call and asks before anything is sent.

Serve needs an Apple Silicon Mac on macOS 14 or later. CereVault runs on macOS 15.2, iOS and iPadOS 17, and visionOS 1 or later.
