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.
