Noema Constellation

One feature, two kinds of continuity

Constellation brings your Noema devices together. Chats and projects sync through your private iCloud database, while models installed on an awake Mac can be selected from another device without copying the model weights.

There is no pairing code, host ID, or IP address to type. Devices signed into the same Apple Account discover one another automatically.

Set up your Mac

1. Open Noema on the Mac that stores the models you want to use.
2. Open Settings → Sync.
3. Turn on Sync chats if you want chat and project continuity.
4. Turn on Reach this Mac from anywhere to allow remote model access.
5. Choose when Noema may keep the Mac awake.
6. Leave Noema running and keep the Mac awake.

Connect from iPhone, iPad, or Vision Pro

1. Make sure the device uses the same Apple Account as the Mac.
2. Open Stored → Constellation.
3. Turn on Sync chats and Use your Mac’s models.
4. Wait for the Mac to show as ready.
5. Find a model under the Mac and press Use.

Noema starts loading the model and chooses a connection route before the first message. Chat opens immediately; if the model is large, the first request waits for that in-progress load to finish.

What syncs

• Chats, messages, titles, favorites, and bookmarks.
• Chat instructions, scratchpads, modes, answer styles, and tool permissions.
• Projects, project instructions, source references, defaults, and archive state.
• Tool history, web results, and route information shown in a transcript.
• Deletions and regenerated turns.

What stays on each device

• Model weights and downloads.
• Datasets, PDFs, source files, indexes, and embeddings.
• Per-device MCP server selections and runtime settings.
• Photo and media attachment files.

Project source references can sync, but the corresponding local source must also exist on a device before that device can retrieve from it.

Force an immediate sync

Open the chat drawer on iPhone or iPad and pull down. Noema pushes local changes, fetches remote changes, merges them, and sends any merge result before the refresh indicator finishes.
