An AI inbox that triages itself, drafts in your voice, and follows up so you don’t have to remember to. ORGANIZE EMAILS YOUR WAY Upstream sorts, flags, and surfaces what needs your attention today. Noise gets filed away. No rules to set up or folders to maintain. It learns how you work and gets out of your way. DRAFTS IN YOUR VOICE. NOT A VOICE. Upstream writes like you. Not like AI pretending to be you. It studies how you write, how you talk to this specific person, and what the thread already sounds like, then drafts from there. The reply is waiting before you've finished reading the email. THE FOLLOW-UP WRITES ITSELF Upstream watches the threads going quiet, writes the nudge, and adds it to your inbox to send. The open loops close themselves. The ball never gets dropped.
