Rubah — a personal AI assistant on your own server
An AI assistant that runs on your own server and actually remembers you
AI assistants have become part of everyday work, but using the mainstream ones means sending your questions, files and internal company information to a server on the other side of the world — something many organizations simply cannot accept, on top of subscription costs, service outages and access restrictions. Rubah answers exactly that need: an AI assistant that runs entirely on your own server, sends nothing outside, and costs nothing per message. Unlike ordinary chatbots Rubah has memory; it remembers what you have told it about yourself, your work and your preferences, so you never have to explain everything from scratch again. Each user can give the assistant its own name, tone and personality, and refine it over time simply by approving or correcting its answers. For companies that means an internal assistant that answers repetitive staff questions, helps draft and summarize text, and keeps organizational knowledge inside the organization. For individuals it means a permanent companion on a home server. Rubah can also live inside a desk device or small robot, giving hardware makers a ready foundation for adding a talking assistant to their product.
Everything an organization needs
Runs on your own server
No question, file or piece of information leaves your organization or home — everything is processed on your own hardware.
Persistent personal memory
Rubah remembers what you've told it about yourself, your work and your preferences, so conversations pick up where they left off.
A personality per user
You choose the assistant's name, tone and character, and every user gets their own version.
Natural conversation
Built on a language model tuned for the local language, so answers read naturally rather than machine-translated.
Learns from your feedback
Approving or correcting answers gradually makes the assistant more accurate and better matched to how you work.
No per-message cost
Unlike cloud services there's no foreign-currency subscription and no charge per message — deploy once, use always.
Dedicated hardware or plain desktop
It can live inside a robot or a desk device and talk to you, or simply run on a computer or server.
Optional help from larger models
For complex questions it can optionally call out to cloud services — a setting you can leave switched off entirely.
