## Quick Start
### macOS
```sh
git clone https://github.com/BasedHardware/omi.git && cd omi/desktop/macos && ./run.sh --yolo
```
Builds the macOS app, connects to the cloud backend, and launches. No env files, no credentials, no local backend.
> **Requirements:** macOS 14+, [Xcode](https://developer.apple.com/xcode/) (includes Swift & code signing), [Node.js](https://nodejs.org/)
### Windows
```powershell
git clone https://github.com/BasedHardware/omi.git
cd omi\desktop\windows
npm install
copy .env.example .env
npm run dev
```
Starts the Windows desktop app from source using the public config in `.env.example`.
> **Requirements:** [Node.js](https://nodejs.org/)
For development worktrees, run the baseline local setup once. It installs the Git hooks and syncs the pinned backend Python environment used by selected pre-push checks; mobile and desktop runtime environments remain opt-in.
```bash
make setup
```
Full Installation
For local development with the full backend stack:
1. Install prerequisites
```bash
xcode-select --install
uv --version
```
2. Clone and configure
```bash
git clone https://github.com/BasedHardware/omi.git
cd omi/desktop/macos
cp ../../backend/.env.example ../../backend/.env
```
3. Build and run
```bash
./run.sh
```
See [desktop/macos/README.md](desktop/macos/README.md) for environment variables and credential setup.
### Mobile App
```bash
cd app && bash setup.sh ios # or: bash setup.sh android
```
Try in Browser
