Most AI assistants live in a chat box. Lida lives on your screen. It's a Windows desktop companion you talk to out loud: it sees the app you're in and answers by voice. Say "show me how" and it points at the exact button. Say "teach me" and it draws the idea on a live board beside your work. Say "do it" and it takes the steps while you watch, asking before anything risky. Its overlay stays hidden from screen recordings, and it only remembers what you approve.
