# Parsaa

> Parsaa is a native macOS AI coding agent for Xcode. It reads your open project, writes Swift, runs builds and tests, launches the simulator, and asks for approval before every code change.

## Product

Parsaa is built for Apple-platform developers who want an AI engineer that works alongside Xcode.

### Core workflow

- Reads the open Xcode project and relevant project files.
- Writes and edits Swift code.
- Builds the app, runs tests, boots the simulator, and reads build and runtime output.
- Shows proposed code changes as diffs and waits for approval before applying them.

### Model options

- Parsaa Cloud provides hosted models with no provider-key setup.
- Bring Your Own Key (BYOK) supports direct requests to the selected provider.
- Local models such as Ollama or LM Studio can run the agent loop without an internet connection.

### Apple documentation

Orchard grounds Apple-related answers in current Apple documentation and helps identify deprecated APIs.
