Jan is an open source alternative to ChatGPT that runs 100% offline on your computer

Getting Started - Docs - Changelog - Bug reports - Discord

Jan is your AI Assistant that runs entirely offline on your desktop. Because in a world where everything is shared, sometimes you just want to keep your conversations between you and your computer—call us old-fashioned.

⚠️ Jan is in active development.

Because clicking a button is still the easiest way to get started:

Download from jan.ai or GitHub Releases.

• Local AI Models: Download and run LLMs (Llama, Gemma, Qwen, etc.) from HuggingFace
• Cloud Integration: Connect to OpenAI, Anthropic, Mistral, Groq, and others
• Custom Assistants: Create specialized AI assistants for your tasks
• OpenAI-Compatible API: Local server at localhost:1337 for other applications
• Model Context Protocol: MCP integration for enhanced capabilities
• Privacy First: Everything runs locally when you want it to

For those who enjoy the scenic route:

• Node.js ≥ 20.0.0
• Yarn ≥ 1.22.0
• Make ≥ 3.81
• Rust (for Tauri)

git clone https://github.com/menloresearch/jan
cd jan
make dev

This handles everything: installs dependencies, builds core components, and launches the app.

If you prefer the verbose approach:

# Setup and development
yarn install
yarn build:core
yarn build:extensions
yarn dev

# Production build
yarn build

# Clean slate (when things inevitably break)
make clean

• make dev - Full development setup and launch (recommended)
• make dev-tauri - Tauri development (deprecated, use make dev)
• make build - Production build
• make install-and-build - Install dependencies and build core/extensions
• make test - Run tests and linting
• make lint - Check your code doesn't offend the linters
• make clean - Nuclear option: delete everything and start fresh

Minimum specs for a decent experience:

• macOS: 13.6+ (8GB RAM for 3B models, 16GB for 7B, 32GB for 13B)
• Windows: 10+ with GPU support for NVIDIA/AMD/Intel Arc
• Linux: Most distributions work, GPU acceleration available

For detailed compatibility, check our installation guides.

When things go sideways (they will):

1. Check our troubleshooting docs
2. Copy your error logs and system specs
3. Ask for help in our Discord #🆘|jan-help channel

We keep logs for 24 hours, so don't procrastinate on reporting issues.

Contributions welcome. See CONTRIBUTING.md for the full spiel.
