Jan is an open source alternative to ChatGPT that runs 100% offline on your computer.
This desktop application provides a private space for you to interact with large language models (LLMs) like ChatGPT, without your data ever leaving your computer. You provide your questions or prompts, and the application generates responses using an AI model downloaded and run locally on your machine. Anyone concerned with data privacy, security, or needing to work offline with AI can benefit from this tool.
41,020 stars. Actively maintained with 262 commits in the last 30 days.
Use this if you need to use an AI assistant for writing, research, or problem-solving and require complete control over your data, ensuring it remains private and offline.
Not ideal if you primarily need to connect to cloud-based AI services without a strong emphasis on local model execution or data privacy.
