Jan.ai is an open-source, privacy-focused AI assistant that serves as an alternative to ChatGPT, running completely locally on your device. It allows you to download and run LLMs (local language models) offline while also offering optional integration with cloud-based model providers—giving you full control over your data and AI interactions. Download and run LLMs (Llama, Gemma, Qwen, GPT-oss etc.) from HuggingFace. Connect to GPT models via OpenAI, Claude models via Anthropic, Mistral, Groq, and others. Create specialized AI assistants for your tasks. MCP integration for agentic capabilities.

Features

  • Download and run LLMs like Llama, Gemma, and Qwen from Hugging Face or use your own GGUF model files
  • Optionally connect to remote AI services such as OpenAI, Anthropic, Mistral, Groq, and more
  • Jan can start a local server (e.g., localhost:1337) that supports OpenAI-style API calls for integration with other tools or interfaces
  • All data stays on your machine; Jan AI can operate fully offline with no internet connection required for local models
  • Build and tailor specialized assistants via plugins or model configurations
  • Available as installable binaries for Windows, macOS, and Linux with support for GPU acceleration (NVIDIA, AMD, Intel Arc via Vulkan or CUDA)
