How it works
Four steps from a spare computer to apps that fit you.
Oikou Host runs open-source web apps on a computer you own and connects them with permissions you approve. Your own Claude Code or Codex, signed in with your Claude or ChatGPT plan, answers questions across those apps and rewrites any of them on a draft you preview. You use them from the Oikou app or any browser.

How do I add web apps?
Pick web apps from the Catalogue, which you reach from your Personal Cloud’s own web page, and add them there. Each one gets its own address on your computer, and opens in the Oikou app or any browser.
How do Oikou’s apps share what they know?
Only through connections you approve. 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.

Can my own AI answer questions across all my apps?
It can. Oikou runs Claude Code or Codex on your own computer, signed in with your own Claude or ChatGPT plan, so a question you ask in one app is answered from what all of your apps know, through the connections you approved. 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.
Usage comes from your own plan and its limits, including background use by apps you’ve allowed.
“Legs this morning, so tonight is salmon, rice and greens. Everything but the broccoli is in the house.”
Can I change how an app works without coding?
Yes. Tell your AI what you’d do differently, in plain language. It rewrites the app on a private draft; you preview it and keep it only if you like it. The apps are open source, so the version you end up with is yours.
- Daily streaks
- Ask for a change
- Weekly streaks, previewed
At launch, updates keep your changes: new versions are merged with yours, and you preview before anything changes.
Which devices can I use my apps on?
On your iPhone, iPad and Mac, and in any browser. Open your apps in Oikou, 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, Android included.
Can other people use my apps without an account?
Yes. Invite anyone to a single app by email. They get a one-time code, install nothing, make no account, and see only the app you shared.
