How It Works
Create a poll and collect responses in your workspace
Type /whennot in any channel
Simply type /whennot in any Slack channel to start creating a new availability poll. The command works in public channels, private channels, and group DMs.
Fill in the poll details
A form opens where you enter the event name, your name, and the date range. Your email comes from your Slack profile. The poll is shared in the channel when you create it.
Team members share their availability
Your team sees the poll in the channel with clear action buttons. They can mark specific dates they're unavailable, indicate full availability, or set a reminder to respond later.
