Chats and projects stay in step.
Start on your Mac, continue on your phone, and keep titles, messages, instructions, favorites, bookmarks, project settings, and tool history together.
Continuity and remote compute · Apple devices
Your chats follow you. Your Mac's models reach you.
Continue a conversation on another device, or use a model installed on your awake Mac from iPhone, iPad, or Vision Pro. No host IDs, URLs, or pairing codes.
One feature, two kinds of continuity
Start on your Mac, continue on your phone, and keep titles, messages, instructions, favorites, bookmarks, project settings, and tool history together.
Select an installed Mac model from another device. The model weights remain on the Mac; only the active request and response travel over the chosen route.
Conversation continuity
Constellation uses your private iCloud database to merge chats and projects across devices signed into the same Apple Account. If two transcripts diverge, Noema keeps a conflict copy instead of guessing which version to erase.
Follows you
Stays on each device
Remote compute
Constellation does not copy a 30 GB model to your phone. It discovers the models on an awake Mac, shows what each can do, and loads the one you choose.
Press Use in Stored. Noema starts the real model load and checks available routes.
The Mac applies its hardware settings and performs inference on the installed model.
Text, tool calls, citations, and supported photos return to the device in your hand.
Connection paths
Noema checks the useful paths when you select a model, prefers the fastest working one, and shows the result in Chat. You do not need to understand networking to use it.
Your device talks directly to your Mac on the same network. This is usually the fastest path.
Use a Tailscale, ZeroTier, or WireGuard address you already control—without opening a router port.
An encrypted peer-to-peer path connects your devices across networks when the network allows it.
When a firewall blocks Direct, the Bridge forwards end-to-end encrypted bytes that it cannot read.
Your private iCloud database carries the request and reply when the faster paths are unavailable.
Tools and local knowledge
The model may run on your Mac, but the device that started the chat still decides which tools are allowed and executes them. A PDF on your iPhone can support a Mac-hosted model without copying the whole library to the Mac.
Models, tools, and photosGetting started
In Settings → Sync, turn on chat sync and Reach this Mac from anywhere.
On iPhone, iPad, or Vision Pro, open Stored → Constellation and enable Mac models.
Choose a model under the Mac. Loading begins and Chat opens with the route visible.
Privacy and control
Off by default. Remote Access requires a deliberate choice on both sides.
Route visible. Chat tells you whether the connection is local, direct, bridged, or using iCloud.
Off-Grid wins. Off-Grid Mode pauses sync, discovery, remote access, and network-backed tools.
Good to know
Noema cannot wake it, and closing a MacBook lid still puts it to sleep.
Some mobile and managed networks require Bridge or Cloud Relay instead.
Chat sync keeps source references, but datasets and attachment files remain local.
A vision model needs its working projector before photo input appears.
