Lumo is a Windows desktop AI email chief of staff. It reads every email as it arrives, files the noise, and gives you a running brief of what's actually happening in your inbox. It drafts replies in your voice using knowledge from your real email history — and its signature rule: it never fabricates your opinion. If a reply needs a decision only you can make, it asks you instead of guessing. Auto-send is off by default, every send has a 5-minute undo, and replies thread properly.
