Jan

Jan is a fully open-source AI assistant that runs entirely on your device, eliminating the need for cloud connectivity or third-party servers. This approach ensures complete privacy—all conversations, preferences, and model data remain securely on your computer, giving you full ownership and control. You can export your data at any time or delete it permanently, with no external tracking or data collection. One of Jan's standout capabilities is its OpenAI-compatible API server running on localhost:1337, allowing seamless integration with existing applications and workflows. This means developers and power users can use Jan as a drop-in replacement for ChatGPT-compatible tools without changing their current setup. The platform is highly customizable, letting you tailor AI assistants to your specific needs and configure global hotkeys for quick access. Jan is actively developed as an open-source project, with transparent development practices and a public roadmap. While the platform is still evolving and may contain occasional bugs, the core team is committed to continuous improvement. A mobile version is currently in development, with progress visible on their GitHub repository and public roadmap for those interested in following updates.
