Private Offline AI Desktop Apps
Private, offline AI desktop apps built with PyQt5: local LLM chat with Ollama and DeepSeek, plus offline Stable Diffusion image generation.
Desktop apps that run AI chat and image generation entirely on your own computer, with no cloud service and no data leaving the machine.
The challenge
Most AI tools need an internet connection and send your prompts to someone else’s servers, which rules them out for sensitive work or poor connectivity.
Our solution
We built two PyQt5 desktop applications that run AI locally. The chat app uses open-source language models through Ollama, including DeepSeek, and can switch between several models. The image generator uses Stable Diffusion and works fully offline once its model has been downloaded.
What it delivers
- Private by design: prompts stay on your machine
- Works without an internet connection after setup
- No per-message cloud costs
