The next interesting wave of AI tools isn't just about coding assistants.

It's about agents that can actually operate software .

That's why UI-TARS Desktop is worth paying attention to. It's an open-source multimodal desktop agent from ByteDance's broader TARS ecosystem, designed around a simple but powerful idea: let an AI agent see the interface, understand what's on screen, and interact with the computer like a user would.

And that's where Lynkr becomes useful.

Desktop agents are powerful — and expensive to get…
