Messages that create outcomes

Live on web, iOS and Android.

Every message is a casbu

A question, a request, a poll or a plan becomes one card with tappable responses and an optional deadline. The reply is one tap, and it stays pinned to the message.

The results live on the card

In a group, every response is counted where everyone can see it: who has answered, who hasn't, and what's leading.

What's due rises to the top

Anything with a deadline is pinned above the feed. When the deadline passes, the outcome goes back to the sender and is recorded.

Anyone can answer

Send to people by email or SMS; they reply with one letter. No account needed.

VIP mode

Urgent casbus arrive one at a time. Answer to advance.
