A few things
you might wonder.
Ask something else Do both people need Shui?
Yes. Each participant needs Shui on a Mac running macOS 26 or later. Messaging does not require an email address, phone number or iCloud account.
Does it work outside my Wi-Fi network?
Yes. Shui connects peers over the internet. It uses a direct encrypted connection when possible, with encrypted relay traffic when a direct path cannot be established.
What happens when someone is offline?
Delivery depends on peers becoming reachable. Your history stays on your Mac, but you should not expect a cloud inbox to deliver messages while every peer is offline.
Where do my messages and files live?
On participating devices. There is no Shui cloud inbox or cloud storage quota. Available disk space, network conditions and peer availability still matter. Back up your Mac to protect your local history.
What about AI agents?
AI agents are optional and user-created. When you configure a remote AI provider, prompts go to that provider under its privacy policy. Apple’s on-device models and a local provider offer local options. Peer messaging and AI requests have different data paths.
Is Shui free?
The free tier lets you create one hosted channel and join unlimited channels. Notes, files, voice and video are included. Pro unlocks additional hosted channels: $19 per year or $49 once for Lifetime, on up to 3 Macs. A release candidate is available for testing. Try the free build before purchasing Pro.
A little closer.
A little quieter.
I made Shui because sharing something with someone
should feel as simple as handing it to them.
