# ShadowQuill
**A local prompt studio that stays on your machine**
[](https://github.com/shadowquillapp/shadowquillapp/stargazers)
[](LICENSE)
## Overview
ShadowQuill turns rough ideas into structured prompts you can actually use. It talks to [Ollama](https://ollama.com) and runs Google Gemma models locally — no cloud API, no account, no network required after setup.
## Quick start
**You need:** [Ollama](https://ollama.com) installed, plus at least one Gemma model pulled.
```bash
# Pull a Gemma model
ollama pull gemma4:latest # Gemma 4
ollama pull gemma3:latest # Gemma 3
# Clone, install, run
git clone https://github.com/shadowquillapp/shadowquillapp.git
cd shadowquillapp
pnpm install
pnpm start
```

```bash
pnpm install # Install packages
pnpm run dev # Dev mode (Electron + Next)

pnpm run check # Lint with Biome
```
## Tech stack
Next.js • Electron • Ollama • React • TypeScript • Tailwind CSS • Vitest • Biome
## How we think about it
- **Offline-first** — Works without internet once Ollama and the app are set up
- **No telemetry** — Nothing phones home
- **Local storage** — Projects, presets, and config live on your disk
