QRX3 AI Chatbot is Now Live!


QRX3 is more than a chatbot. It's your private, local AI companion, optimised for speed, privacy, and complete offline usage.
🧠 What is QRX3?
QRX3 is an open-source AI chatbot that runs entirely on your machine using Ollama for local LLMs. From start to finish, it works without internet and stores your encrypted data locally under your account.
No third-party APIs. No cloud processing. Just you and your AI.
🛡️ Key Features
👥 Multi-user authentication support
🎨 Clean PyQt5-based UI with Minimalist style
🗂️ Persistent chat history (soon to be encrypted!)
✅ Optimised and tested on Mac Silicon M2
💻 Tech Stack
Python for backend logic and encryption
PyQt5 (GUI version)
Ollama for LLM management
Fully local file-based storage
🚧 What's Next?
I’m currently:
Looking to integrate a more optimised model in Ollama for either Image generation or chat
Planning cross-platform tweaks for Windows, Linux and Intel based Mac
Exploring chat history encryption (should I do it? Let me know!)
Acknowledgements
This project wouldn’t be possible without:
Ollama for enabling easy local LLM deployment
Open-source LLMs like Llama3
PyQt5 for the fast and clean UI
The open-source community for constant inspiration
