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.
Hey Product Hunt! I'm Balwinder Singh, solo founder of Lumo.
I built this because my own inbox was eating the first two hours of every day. 100+ emails, and the 3–4 that actually mattered were buried under newsletters and receipts. Filters didn't help — they sort senders, they don't understand messages.
Lumo is a Windows desktop app that watches your Gmail 24/7, files the noise, and gives you a short brief of what's actually happening. When something needs a reply, it drafts one in your voice, learned from your own sent mail.
The design decision I'm proudest of: Lumo never fabricates your opinion. Every AI email tool I tested would confidently answer "yes, Tuesday works" or "sure, 15% off" on my behalf — guessing. Lumo detects when a reply needs a decision only you can make, and asks you a plain question instead. You answer, it drafts around your actual answer. Auto-send is off by default, every send has a 5-minute undo, and replies thread properly.
Being fully honest, because it's a beta: it's Windows + Gmail only right now, the installer isn't code-signed yet (Windows shows "More info → Run anyway"), and Google shows its "unverified app" screen until my verification clears (Advanced → continue). I'd rather tell you here than surprise you mid-install.
The deal: it's free for the first 100 founding users, and you get me personally on support — I onboard you, I fix what you report, usually same day.
I'll be here all day answering everything — including "why should I trust an app with my email?" Fair question, ask it.
One thing I'd love is a way to set per-contact voice profiles, so the draft tone shifts automatically when I'm writing to my boss versus a close client. Right now it sounds consistent across everyone, which doesn't match how I actually write. Would make the replies feel even more like me.
