Jan - Local AI Assistant

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.

Build from Source

For those who enjoy the scenic route:

Prerequisites

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

Quick Start

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

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

Alternative Commands

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

Available Make Targets

• 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

System Requirements

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.

Troubleshooting

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.
