01 — WHAT IT DOES
No autoresponse. No rewrites. No summaries. It does these three things and stops.
Gmail and Slack DMs, in one queue. It sees what came in — not what you've already replied to.
Trained on 2,000 of your sent messages. Your sentence length, your phrasing, your sign-off. Sounds like you, not a bot.
The draft sits in your inbox. You read it, tweak it if you want, send if you mean it. The button stays in your hand.
02 — SEE IT WORK
A message lands. The draft is written. You hit send. Roughly four seconds, start to finish.
03 — THREE STEPS TO LIVE
Sign in with Google and Slack. OAuth, no passwords. 30 seconds.

Every new message gets a draft. You read it. You press send.
04 — VOICE MATCH
Three of Hudson's actual drafted replies. The incoming is real. The draft is what Mouthpiece wrote. Edit: none.
Hey Hudson, can we push the Friday demo to next week? Marcus is out.
nah let's keep friday — i can present without marcus. cool to skip his bit?
Quick favor — could you take a look at this contract and tell me if anything looks off?
sure send it over. give me till tomorrow night. fyi i'm not a lawyer so it'll be a vibes-check.
Loved the talk yesterday. Would you be open to a 30-min call sometime next week to dig into your approach?
