## O que é Cedar?

Cedar is presented as Cedar-OS, an open-source framework for building AI-native applications. The homepage describes it as the missing frontend layer for AI and emphasizes a full-stack implementation for teams that want to ship agent-driven experiences.

Its core purpose is to provide ready-made UI and workflow primitives for AI interactions, including streaming messages, tool execution, voice interaction, application state access, and change review. The framework is positioned for teams that want custom, ownable components rather than a closed chat widget.

## O que Cedar pode fazer?

### Streaming and tool calls

Render real-time messages while agents execute tools, so the UI can keep users informed during long-running actions.

### Voice integration

Support voice-powered agent interactions for workflows that are not limited to typed chat.

### State access

Let agents read and write application state, which makes the framework suitable for stateful interactions instead of isolated prompts.

### Diff and history

Track AI changes with diff and history views, including user approvals and history management.

### Flexible chat surfaces

Offer multiple chat presentation options, including floating chat, side panel, caption, and embedded components.

### Owned UI components

Provide a component library in a Shadcn-style model so teams can own and customize the code they ship.

## Casos de uso

### Agentic product UIs

Use Cedar when you need an AI interface that streams responses while also running tool calls in the background.

### Stateful workflows

Use the framework for applications where the agent must read or update application state instead of working in a stateless chat flow.

### In-product assistant experiences

Use the different chat component formats to place AI assistance in a floating widget, side panel, caption area, or embedded product surface.

### Reviewable AI changes

Use the diff, history, and approval flow when users need to review and confirm AI-generated changes before they are applied.

### Customizable front ends

Use the ownable component model if your team wants to customize shipped UI code instead of embedding a fixed third-party widget.
