Do I need programming knowledge to use AppJuice?

No. Describe what you want; AppJuice keeps code out of sight and handles the app structure, runtime, and AI wiring. Builder messages and progress are written in plain language, not raw agent logs.

How is AppJuice different from agent tools with app plugins?

Those tools connect one general agent to apps it can operate, or generate projects hosted on their cloud. AppJuice inverts the relationship: it builds apps that live on your machine, each with its own agent inside — and they keep working after the builder session ends, with whichever providers you choose.

Can AppJuice apps include AI actions or agents?

Yes. Apps can include direct AI actions or app-specific agents for chat, skills, tool calling, and multi-step work.

What can an app's AI access on my machine?

Only the files, folders, tools, and actions you approve through AppJuice-controlled runtime paths.

Can I bring my own AI provider or local model?

Yes. Configure your own cloud providers, models, or local models once, then use them across the builder and apps.

Local-first AI app platform

Make your own private AI apps. Each with its own AI agent inside.

Q: What is AppJuice?

AppJuice is a local AI app platform for creating and running private apps on your computer, with a built-in local runtime.

Q: Is AppJuice a cloud app builder?

No. AppJuice builds and runs apps locally; no cloud deployment step is required.

Q: What data leaves my machine?

Your app files and local data stay on your machine by default. Cloud AI providers receive request context only when you choose a cloud model for that action.

Q: Do shared apps include my private data?

No. Shared apps are app packages/templates, not your runtime data, files, sessions, or provider keys.

“Won't coding agents build this too?”

Coding agents deliver code.

AppJuice gives every app a managed runtime, lifecycle, and ready-made AI foundation.

Private by default

Useful system access, inside visible boundaries.

Your app can do real work with approved files and tools. AppJuice constrains that access and makes the boundary explicit.

Secrets stay separate

Provider credentials do not need to be embedded in app code.

Sandboxed by default

Platform-controlled execution keeps capabilities within defined limits.

You choose what leaves

Use local models, or deliberately send selected context to your AI provider.

Sharing is checked

Apps published to the Juicery go through safety checks before sharing.

Local-first does not mean powerless. It means capabilities remain tied to your intent, approvals, and environment.

What is AppJuice?

A local AI app platform for creating and running private apps on your computer, with a built-in local runtime.

Do I need programming knowledge?

No. Describe what you want in plain language. AppJuice handles the app structure and runtime; you use and refine the result.

Is AppJuice a cloud app builder?

No. AppJuice is local-first: the platform and your apps run on your machine. You can still choose cloud AI providers when an app needs them.

Can apps include AI or agents?

Yes. An app can include an agent connected to your chosen provider and work with platform-approved tools, files, and context.

What can an app's AI access?

Only the capabilities and paths permitted by the app, platform safety controls, and your approvals. Access is not unrestricted.

What data leaves my machine?

Your app data stays local by default. If you use a cloud AI provider, the context needed for that request is sent to the provider you selected. A local model can keep AI processing local too.

Do shared apps include my private data?

No. The shareable app package is separate from your personal runtime data, and shared apps are safety-checked before publication.

Can I bring my own AI provider?

Yes. AppJuice is designed so apps use the providers and models you configure, rather than locking every app to one AI company.

Start with the desktop app.

Download AppJuice for macOS, make your first private app, and keep it on the machine where your work already lives.

Apple Silicon Intel

Windows, Linux, and home-server editions are planned for later.

I built AppJuice so your ideas can stay close to you.

Your app should not disappear when a chat ends, depend entirely on one model provider, or force your private work into someone else's product. AppJuice keeps the idea at the center: a real interface, persistent local data, and an agent runtime you can continue to shape.
