You can't plan the carpool until you know who's actually coming.
whoosin is the simplest hiking group RSVP tool you'll ever use — it finds the invite already in your Sent mail, reads every reply automatically, and shows you a live yes/no/maybe tally so you can plan carpools and pick the right trailhead the moment you have enough people.
The headache: You send the trail email, replies trickle in over three days, and you're still manually counting threads the morning of the hike trying to figure out how many cars you need.
- Join the beta, then connect your Gmail — whoosin finds the invite you already sent. Nothing to set up.
- 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.
- 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.
