Side-by-side comparison to help you choose the best tool.

Jan

free
4.3 / 5.0

Jan is an open-source desktop application for running AI models locally - a privacy-first alternative to ChatGPT that runs entirely offline. Like LM Studio, it provides a chat interface for local models, but also supports connecting to remote model APIs. Jan is fully open-source with an extension platform, making it the most customisable local AI desktop app.

Best for: Privacy-first users and developers wanting a fully open-source, offline-capable AI chat app with extensibility and model flexibility
