01 — ACCESS
Universal by design
Designed around screenshots and standard input events, not a single vendor's proprietary computer-use interface.
OPEN SOURCE · DEVELOPMENT PREVIEW
Computer use,
without boundaries.
AI shouldn't need a proprietary computer-use API to interact with your desktop. UCU bridges visual reasoning and real mouse-and-keyboard actions through an independent local runtime.
01 / THE IDEA
Capability belongs to the agent.
Not the platform.
UCU is designed for AI systems that can understand screenshots but lack built-in desktop control. Rather than modifying or retraining the model, it provides an external execution bridge.
02 — CONTROL
Runs where you work
A local runtime executes actions on the user's machine. The website itself does not request desktop access.
03 — FEEDBACK
Verify every step
The proposed loop re-observes the screen after actions, so an agent can detect changes and correct its next move.
02 / EXECUTION LOOP
See. Reason. Act. Verify.
A simple interaction contract keeps the model and operating system separate. UCU handles the bridge; the connected agent supplies visual interpretation and decisions.
01 / OBSERVE
Capture
Acquire a real desktop screenshot.
02 / REASON
Interpret
The AI agent decides the next action.
03 / EXECUTE
Interact
Local mouse and keyboard input.
04 / VERIFY
Check
Capture again and evaluate the result.

03 / ENGINEERING PRINCIPLES
Power needs boundaries.
Computer control is a high-trust capability. The runtime architecture is being developed with explicit permissions and observable actions as priorities.
Local-first control
Keep desktop execution in a local process and make trust boundaries explicit. Avoid silently turning a website into a remote-control console.
Traceable operations
Prioritize action logs, verification and recovery pathways, so users can inspect what the runtime attempted and what actually happened.
No model retraining
UCU is not a foundation model. The design integrates external capable models without requiring changes to their weights.
Open engineering
Apache License 2.0, public repository, and documentation as the runtime matures. No unverified installer is published here.
04 / OPEN SOURCE
