Personal Apps: Make Any App Your Own
A Caiioo "app" bundles related pieces—a mode, skills, variables, cards, views, and workflows—into one installable package. Anything you install from the Community Hub is an app. Personal Apps are the apps you own: copies you've forked from the Hub, sessions you've saved, or apps you've built from scratch. They're first-class—identical in every way to Hub-installed apps—and they sync across your devices.
You'll find them all in Settings > Tools, Modes & Apps > My Apps.
Fork a Hub App
Found a Hub app that's almost what you want? Fork it and edit your copy—the original on the Hub never changes.
- Go to Settings > Tools, Modes & Apps > My Apps
- Pick a Hub app and choose Fork
- It becomes a personal app you can edit freely
Editing a built-in or Hub mode forks it automatically the moment you change it—see Modes for the "Forked from X" banner and the Reset to original button.
The App Editor: Six Primitives
Open any personal app in My Apps and you get a dedicated editor for each kind of thing an app can contain:
| Primitive | What You Edit |
|---|---|
| Modes | Name, system prompt, and which tools the mode can use |
| Skills | Name, prompt, and tags |
| Variables | Name, label, type, and default value |
| Cards | Glanceable inline summaries the app renders |
| Views | Full-panel app surfaces |
| Workflows | Multi-step sequences the agent runs |
Each editor surfaces just the fields you'd normally want to change—everything else about the primitive is preserved untouched when you save. You can also remove individual primitives from an app, or start completely fresh with the New app button.
Save a Session as an App
Had a great conversation you'd like to reuse? Just ask the AI to "save this as an app" (or similar). The agent snapshots the session—its mode, the skills it leaned on, any open slates—into a draft personal app. From there, refine it in My Apps like any other app.
Everything Syncs
Personal apps sync across your devices the same way Hub installs do. Fork or build an app on your Mac and it shows up on your iPhone, and vice versa.
