What it does

Runs entirely on hardware you control, searching the web and composing cited answers, with the model behind it either local through Ollama or a cloud provider — OpenAI, Claude, Gemini, Groq — if you prefer capability to isolation. The privacy claim holds only on the local path: pick a cloud model and your questions go there, and web searches always leave traces at the sites queried. Docker deployment. MIT.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

Vane FAQ

Is Vane free?: Vane itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
Do I need to install anything or write code to use Vane?: It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
Does Vane work on a phone?: No. It needs a computer.
Can I use Vane commercially?: The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
