Our review
Jan is an open-source offline AI assistant that runs open models such as Llama, Qwen and DeepSeek on your own hardware, keeping data on-device and privacy-friendly; it can also plug into cloud APIs as a complement. The interface is clean and cross-platform, and it's the main rival to LM Studio.
No subscription and completely free, but local inference depends on your hardware, so model capability is bounded by your machine — a great fit for privacy-sensitive or offline users.
