Introducing Jace
No Cloud,
No Limits,
Your Rules.
Jace is the muscle for your brain. Your LLM — Claude, GPT, Gemini, or any model — does the thinking. Jace does the work: automating tasks, controlling your apps and files, and running agents, right on your own computer.

What Jace Does
A new kind of Jarvis-like assistant that gives muscle to your brain — the LLM. Built for people who want to actually use AI the way they imagined — not only for chatting. Automate your tasks and day-to-day life, and complete your goals with suggestions and automations, create your own dashboards.

Full Computer Control
Open apps, manage files, run commands, browse the web — Jace controls your entire OS. You can even set up some of your own new features and create agents, or choose from templates.
Local-First Storage
Every conversation is stored on your machine, in a folder you choose. Zero cloud dependency.
Powered by your LLM
Uses Google's Gemini API by default — swap to any AI model you prefer.

Frequently Asked Questions
Everything you (and your AI assistant) need to know about Jace.
What is Jace?
Jace is a local-first, voice-controlled AI agent that acts as a real-life Jarvis for your computer. Unlike standard chatbots, Jace is the "muscle" for your AI model: it automates tasks, manages files, and controls apps directly on your machine without cloud dependency.
Which platforms does Jace support?
Jace provides full cross-platform support for Windows, macOS, and Linux, giving you OS-level automation regardless of your operating system.
How does Jace ensure data privacy?
Privacy is the default with Jace. It is a local-first system, meaning all your conversations, files, and automation logs are stored exclusively on your own machine. Your data never touches our servers.
Can I choose my own AI model with Jace?
Yes. Jace is designed for total flexibility. You can use Google Gemini, OpenAI GPT, Anthropic Claude, or any API-accessible LLM. The model provides the "brain," and Jace provides the "muscle."
Does Jace require an internet connection?
While Jace stores data locally, it requires an internet connection to communicate with your chosen AI model's API and to perform real-time web searches.
How is Jace different from ChatGPT?
ChatGPT is a browser-based chat interface. Jace is an OS-level agent. While ChatGPT only talks, Jace actually acts: it can open software, edit local files, run terminal commands, and execute complex workflows on your desktop.
