NodeTool vs Jan

Open and local — plus everything past chat.

Jan is an open source, offline-first desktop app for chatting with local LLMs — a clean, private local ChatGPT alternative. NodeTool is open source too, but a node-based canvas: it runs local models via Ollama, MLX, and llama.cpp and adds native image, video, and music generation, agents, and RAG on the same graph.

A great chat app, or a whole canvas

Jan does one thing well and openly: private, offline-first chat with local models, with a UI that feels like a local ChatGPT. If that's what you want, Jan is a lovely, focused choice and fully open source. NodeTool aims wider: it runs the same local models via Ollama, MLX, and llama.cpp, but puts them on a node-based canvas alongside native image, video, and music generation, agents, and RAG — so a local model can drive a whole workflow, not just a chat window. Both are open source; the difference is scope.
