whoosin

You need six players. Not five, not seven — six.

whoosin is a volleyball RSVP tool that watches your Sent mail for the invite you already sent, reads every reply as it lands, and keeps a live count — so you know the exact moment you hit six.

The headache: You sent the email, now you're squinting at your inbox doing mental arithmetic, terrified you'll show up one body short of a full rotation.

1. Join the beta, then connect your Gmail — whoosin finds the invite you already sent. Nothing to set up.
2. Your group just replies from whatever email they already use — no app, no account, no link. whoosin reads each reply as yes / no / maybe (or approve / reject, or a guest count) with AI.
3. You get a live list — a running headcount when you ask for one — with manual overrides and one-tap follow-up drafts.

Private by design. Your mail is read in your browser, replies are sorted by AI for a moment and then discarded, and only the answer — yes, no, maybe — is kept. No ad trackers. Follow-ups are drafts in your Gmail; whoosin never sends mail as you.
