What is Jan?
Jan is an open-source alternative to ChatGPT, positioned as a desktop personal assistant for working with local and cloud-based AI models. It provides a conversational interface for everyday questions and model exploration, making it relevant to people who want to try open models, keep their AI workflow in a desktop app, or switch between different model options. Its primary product form is a desktop application for individual users, developers, researchers, and AI enthusiasts.
A typical Jan workflow starts with choosing an available open model or connecting a cloud model such as GPT or Claude, followed by entering questions in the chat interface and continuing the conversation. Local models support an on-device route, while connected online models provide another way to work when that fits the task. The official site also presents Jan Agent and a self-hosted backend as separate parts of the broader product ecosystem, while Jan itself centers on model selection and desktop conversation.
Key features of Jan
Local Model Chat
Jan lets users run open models in its desktop application and interact with them through a conversational workflow. This is useful for exploring model behavior, developing ideas, and handling everyday prompts within a local AI workspace.
Cloud Model Connections
Alongside local models, Jan can connect to cloud models such as GPT and Claude. Users can therefore keep a similar chat workflow while choosing between available model sources for different questions or working preferences.
Open Model Selection
The product provides a way to choose open models and also supports plugging in preferred online models. This suits users who want to explore alternatives, build a personal set of model options, and change the assistant used for a particular task.
Desktop Conversation Workspace
Jan brings model selection and chat interaction into a desktop workspace. Users can download the application, select a model, and begin entering prompts, making it suitable as a standalone AI conversation tool alongside regular computer work.
