Open Calendar Slots Extension

Booking links are efficient, but they feel transactional. Sometimes you want to offer someone your time, not send them to a scheduling page. Open Calendar Slots reads your Google Calendar, finds the gaps between your meetings, and gives you a clean list of times you can paste into any message. Personal scheduling, without the back-and-forth.

How to use

  1. Install the extension from the Chrome Web Store.
  2. Click the toolbar icon, then Sign in with Google and grant calendar read access. A popup will appear — press allow.
  3. Pick which calendars and weekdays count as “busy”, set your work hours, minimum slot length, and buffer time before/after meetings.
  4. Click Find Free Time, then Copy to Clipboard. Paste into any email or message.
