Add Calmy to Slack - free
Book meetings, share availability, and let AI schedule across your team - right inside Slack. Type /calmy in any channel and you're done.
Free forever · Works with any Slack workspace
Three simple steps
Click 'Add to Slack'
Authorize Calmy in your workspace. Takes one click - no admin approval needed in most workspaces.
Create your Calmy account
10 seconds with Google. Connect your calendar so Calmy knows your availability.
Type /calmy in any channel
Book a meeting from chat. Calmy finds the slot, confirms it, and adds it to both calendars.
Quick questions
Is it really free?
Yes. The Slack integration is free on every Calmy plan, including the Free plan. Upgrade to Pro ($9.99/mo) only if you need more than one connected calendar.
Who can install Calmy in a workspace?
Any Slack member can install Calmy. Some workspaces require admin approval - if so, Slack will prompt you to request it during install.
What data does Calmy access?
Just enough to book meetings: your workspace's public channels (for the /calmy command), and member emails so we can match Slack users to Calmy accounts. We never read message history.
Can I remove Calmy later?
Yes - uninstall from your Slack workspace settings any time, or disconnect from Admin → Slack inside Calmy.
