Every groupchat gets an agent. Each convo is a groupchat with an agent in it. It keeps up with the thread so nobody has to — who's in, when, where, what got decided, what everyone said they'd bring. Then it turns forty messages into something you can actually use. You’re in control of what your agent sees — and doesn’t. AGENTS LISTEN SO YOU DON'T HAVE TO SCROLL Plans get made in the middle of the chaos. Your agent keeps track. Nine confirmed for the match. Kickoff at 7:30. Louis called out the pizza place. Ask it later and it just knows — no one has to scroll back three days to find the address. YOU CONTROL WHEN YOUR AGENT SPEAKS UP Three settings, one tap. Listen: it only speaks up when someone says "Agent." Chat: it chimes in anytime it can help. Pause: it never sees the messages. Ever. GET THINGS DONE WITHOUT BLOWING UP THE CHAT Ask your group's agent something 1:1 — what was that pizza place, when does the flight land, what did we decide — and get an answer without twenty phones buzzing. Same agent, same context, private thread. IT MAKES THINGS AND KEEPS THEM HANDY Itineraries, lineups, notes, running lists, receipts. Everything your agent makes lands in Things, right in the chat, ready to open, edit, or share. NO SIGNUP, NO PHONE NUMBER Scan, tap, or AirDrop into a convo. Chat instantly with anybody. WHY WE BUILT THIS An agent in the group chat should be a great listener, not an annoying yapper or a surveillance bot. So we put the group in control: it hears what you let it hear, it speaks when you let it speak, and it makes useful stuff for the crew.
