Powerful scheduling features designed for teams who live in Slack

Automatic reminders via Slack DM and email for team members who haven't responded.
See response counts update live. View detailed availability on the web dashboard.
Get started in seconds with our simple workflow
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.

A modal opens where you enter the event name, your email (for notifications), and select the date range. The poll will be shared in the channel after creation.

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.

Respondents get instant confirmation. The poll message updates in real-time showing the response count. Click "View Results" to see detailed availability on the web.
