Alpaca – New GTK4 App to Chat with AI Offline

Want to chat with AI models locally without internet connection? Here’s a simple app can do the job in Linux Desktop!

It’s Alpaca, a free open-source application written in Python programming language. It uses Ollama as backend to manage and chat with multiple AI models, without needing any API keys.

By using GTK4 plus Adwaita toolkits, it provides a modern and simple graphical interface that’s well integrated into Ubuntu, Fedora Workstation and other Linux with GNOME desktop.

The app downloads the AI models to your local computer, so you can chat locally without privacy concerns.

It features Meta Llama 3, Google Gemma 2, Microsoft Phi3, Llava AI models in the first launch welcome dialog. While, there are lots of other AI models available in the management dialog, including Alibaba Qwen2, Deepseek Coder V2, Mistral AI, Command R, Openchat, and more!

It as well supports importing AI models from GGUF files, though the feature is experimental at the moment of writing.

Alpaca allows you to chat with multiple AI models in same conversation, supports image recognition (with compatible models), document recognition, code highlighting, YouTube recognition, PDF and Website recognition. As well, it supports importing and exporting your chats.

As the AI models are stored in local system, the data can take dozens of GB disk space, depends on how many models you downloaded. And, it can cause high CPU usage (especially for low end PC) while answering your questions.

For choice, user can setup Ollama server in another machine, then use this app to connect remotely.
