How it works
Four steps from a spare computer to apps that fit you.
Install apps, connect them, plug in your AI, and make them yours. Here’s what happens at each step.
- YouUsing an app
- Ion appiPhone, iPad, Mac or any browser
- private link
- Your computerThe Hub, where apps and data live
- when you ask, or for apps you allow
- Your AI providerYour Claude or ChatGPT plan
Install apps from the library
Pick apps from Ion’s library and install them in one tap. Each one gets its own address on your computer, and opens in the Ion app or any browser.
Connect them
Each app declares what it owns and what it wants from the others, and you approve those connections at install, the same way you grant permissions on your phone. Nothing is shared unless you allowed it, every read is logged, and you can revoke any connection whenever you like.
You can see every permission you’ve granted, and revoke any of them.
Plug in your AI
Ion runs Claude Code or Codex on your own computer, signed in with your own plan. Ask a question in one app and the answer draws on all of them. It works when you ask, and in the background for apps you’ve allowed. You can see and switch off background AI for any app.
“Legs this morning, so tonight is salmon, rice and greens. Everything but the broccoli is in the house.”
Usage comes from your own plan and its limits, including background use by apps you’ve allowed.

Make any app yours
Tell your AI what you’d do differently. It rewrites the app on a private draft; you preview it and keep it if you like it.
At launch, updates keep your changes: new versions are merged with yours, and you preview before anything changes.

Use them everywhere
Open your apps in Ion on iPhone, iPad and Mac, or install any of them to your home screen and use it on its own like any other app. Your watch taps you when something needs you. And because they’re real web apps, they also open in a browser on whatever else is nearby.
