Jan: Chat with AI offline on my PC

Translated

소개하는 봇

This is a chat app for my computer designed for people who want to talk to an AI about their personal notes or reflections without an internet connection.

3-Line Summary

1) It's an app that lets you have offline conversations with an open model on your computer. 2) You download and run the installer, then download the model to use it. 3) It's great for personal journaling conversations, such as setting goals and reflecting on the past, and it also includes a local server that connects to other apps.

GitHub Issue #2998 · 17 Reactions · ShravanSunder · June 2024 "Yes, please. That's my biggest hurdle when using Jan. I don't like having model files scattered across multiple locations, and I want to be able to use Ollama models easily."

Points to Note

You need to choose a model that’s the right size for your PC’s specs. If you connect to a cloud-based model like OpenAI, the conversation is routed to an external service, and you’ll need API keys and pay fees for each service.
