Bluethenics builds software for people who want more from their machines. Our current focus is Jace — a Jarvis-like AI assistant that lives on your computer: voice-first, local-first, and powered by the LLM you choose.
Jace is the project Bluethenics is building right now — a personal AI assistant that runs entirely on your own computer. Think Jarvis, but private and under your control. Most AI today can only talk. Jace gives the brains (your LLM) the muscles to act: it opens apps, manages files, runs commands, browses the web, and automates your day-to-day work.
Talk to it naturally with your voice, or type. Every conversation is stored locally in a folder you choose — nothing is forced into the cloud. Bring your own model: Jace runs on Google's Gemini by default and lets you swap in GPT, Claude, or any API-accessible LLM you prefer. Build your own agents, or start from a template.
Three steps between you and a smarter computer.
Install Jace, pick your LLM, and choose where your conversations are stored.
Say the wake word or press a key, then talk to Jace like you'd talk to a person.
It responds, executes the task, and logs everything locally. You stay in control.
Whether you want to automate your workflow or simply stop typing — Jace meets you exactly where you work. ++++ ```
Automate repetitive tasks, chain actions together, and run your machine hands-free. Synco turns intent into action.
Build custom agents, wire up your own tools, or start from a template. Synco is yours to extend and shape.
Set goals, get suggestions, and let Synco handle the busywork — files, apps, and day-to-day admin while you focus.
Conversations stay on your device, in a folder you choose. No cloud lock-in, no data harvesting — ever.
Synco isn't another chatbot. It's a new kind of Jarvis-like assistant that gives muscles to your LLM — built for people who want to use AI the way they always imagined, not just for chatting.
Cloud assistants send everything you say to someone else's servers. Synco flips that around: it runs on your own hardware, stores every conversation in a local folder you control, and never depends on the cloud to work. Privacy isn't a setting you switch on — it's the foundation the whole thing is built on.
Synco uses Google's Gemini out of the box, but you're never locked in. Point it at GPT, Claude, or any API-accessible model and switch whenever you like. Your assistant, your choice of brain — and your data stays yours.
Most AI stops at the answer. Synco keeps going — it carries out the task. Ask it to organise a folder, draft and send a message, pull something off the web, or kick off a multi-step routine, and it does the work on your machine.
Set goals and let Synco suggest and automate the steps to reach them. Build your own agents for the things you do every day, or start from a template and tweak it. Over time, Synco becomes the layer between what you want and what your computer actually does.
All the capability. None of the lock-in.
