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
Noema Constellation
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
Your devices become one private system.
Continuity
Mac-sized models travel without moving.
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
Pick up the thought, not the setup.
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
- Chats, messages, and deletions
- Projects and their instructions
- Bookmarks, favorites, and modes
- Tool history and route receipts
Stays on each device
- Model weights and downloads
- Source files, datasets, and indexes
- Per-device MCP selections
- Photo and media attachment files
Remote compute
The model stays on your Mac.
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.
Choose a Mac model.
Press Use in Stored. Noema starts the real model load and checks available routes.
Run where the weights live.
The Mac applies its hardware settings and performs inference on the installed model.
Keep one conversation.
Text, tool calls, citations, and supported photos return to the device in your hand.
Connection paths
The route is chosen for you.
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.
- 01Same place
Local Network
Your device talks directly to your Mac on the same network. This is usually the fastest path.
- 02Your private mesh
Private Link
Use a Tailscale, ZeroTier, or WireGuard address you already control—without opening a router port.
- 03Device to device
Direct
An encrypted peer-to-peer path connects your devices across networks when the network allows it.
- 04Encrypted fallback
Noema Bridge
When a firewall blocks Direct, the Bridge forwards end-to-end encrypted bytes that it cannot read.
- 05Broadest compatibility
Cloud Relay
Your private iCloud database carries the request and reply when the faster paths are unavailable.
Tools and local knowledge
Your device keeps control.
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.

Getting started
Turn it on. Your devices find each other.
- 01
Prepare the Mac
In Settings → Sync, turn on chat sync and Reach this Mac from anywhere.
- 02
Open Constellation
On iPhone, iPad, or Vision Pro, open Stored → Constellation and enable Mac models.
- 03
Press Use
Choose a model under the Mac. Loading begins and Chat opens with the route visible.
Privacy and control
Connected only when you choose.
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
A clear boundary beats a hidden surprise.
A sleeping Mac cannot answer.
Noema cannot wake it, and closing a MacBook lid still puts it to sleep.
Direct is network-dependent.
Some mobile and managed networks require Bridge or Cloud Relay instead.
Files do not silently migrate.
Chat sync keeps source references, but datasets and attachment files remain local.
Capabilities reflect real files.
A vision model needs its working projector before photo input appears.
