How it works

Three steps to freedom

Stop wasting time updating multiple platforms. Let Callout handle the busywork while you focus on what matters.

Connect

Link your accounts once. Slack, Google Calendar, GitHub, Teams - we support all the platforms you use daily.

Schedule

Create a time-off entry with your dates, message, and emoji. Set it for today or schedule it weeks in advance.

Relax

Your status updates automatically across all platforms. When you return, everything reverts back to normal.

Integrations

All your tools, one click

Connect the platforms you use every day. When you take time off, they all update together.

Slack

Set your status with a custom emoji and message. Post to your team's #out-of-office channel automatically.
