## Choose where to start

AppJuice runs apps on your computer. Each app has its own interface and data. It can use AI for a specific action or include an Agent that works through a task with you. You can create an app by describing what you need, install an existing app, and change it later.

- [First time here?](https://appjuice.app/guide/getting-started/) Install AppJuice, connect an AI service, and create your first app.

- [Want to create or change an app?](https://appjuice.app/guide/build/) Start with Brew or open an app in Tweak.

- [Want AI features in your app?](https://appjuice.app/guide/apis/) Ask Builder to add an assistant, a summary button, or another AI action.

- [Want help with a task right now?](https://appjuice.app/guide/one-shot/) Use One Shot to work with information and files without first creating an app.

## What the platform provides

You describe what you need; Builder creates the app and helps you change it. Apps can combine forms, records, files, AI actions, and assistants in one workflow. The features available in each app depend on how it was built and the services you have connected.

Add AI actions: Ask Builder to add summaries, image generation, transcription, or web research. Connect the services those actions need in Settings.

Work with an assistant: Add an Agent that can discuss a task, use tools, work with attachments, and produce files for you to review.

Work with local files: Let an app work with approved files and folders, or save a generated result. Access remains subject to the app's permissions.

Use and Tweak: Use an app for its normal task, then open Tweak when you want to change how the app works.

## Local operation and connected services

Apps, sessions, and private runtime data are stored locally by default. A cloud AI request sends its required context to your selected provider. Supported local models can keep inference on the host computer; web search, external services, and publishing still need their respective connections.
