We built the AI assistant we wanted to use
Most voice assistants send every word you say to someone else's server. We kept asking: why can't an AI assistant run on hardware you already own? So we built one.
The problem we saw
Your conversations, your calendar, your emails — existing assistants process all of it on infrastructure you don't control. Your data becomes their product. Cloud costs eat into your wallet. And when you disconnect, the “assistant” forgets everything.
Modern GPUs can handle capable language models locally. Modern CPUs can process speech in real time. The technology was ready — someone just needed to build the product that put the user first.
Your hardware. Your data. Your assistant.
The downloadable version of Hey Jarvis runs entirely on your own computer. Your voice never leaves your room. Your data never leaves your drive. There are no per-query cloud costs eating into your wallet.
The browser version gives you instant access to the same capable assistant, powered by frontier AI models. Try it now, download it later.
What we believe
Privacy by default
Your voice stays on your hardware. Your data stays on your drive. No cloud processing fees, no data harvesting, no exceptions.
Actions, not answers
Jarvis does not just chat. It sends emails, books meetings, messages contacts, and controls your music. A real assistant, not a text box.

Built by BPS Group
BPS Group is a UK-based software company building tools that put users first. Founded by Ben Stonehouse, the team combines deep experience in AI engineering, systems architecture, and product design — brought together by the shared frustration that existing voice assistants were either too limited or too invasive.
Hey Jarvis is our flagship product — built because we wanted an AI assistant we could actually trust. We use it ourselves every day. That's the best quality guarantee we can offer.
