Slotcheck

See your Google Calendar while booking meetings on any scheduler.

Booking a meeting means checking two things at once: the times someone is offering, and the times you're actually free. Every scheduling tool shows you the first. None of them show you the second. Slotcheck fills in the other half. Open any Calendly, Cal.com, HubSpot Meetings, or SavvyCal page and your Google Calendar appears in Chrome's side panel, on the same date you're looking at. Pick a different day on the booking page and the calendar follows automatically. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES • Follows the date you select — click a day on the scheduler, your calendar jumps to it • Full 24-hour timeline, scrolled straight to your first event of the day • Overlapping meetings render side by side, so you can see genuine double-bookings • Multi-day events show correctly on every day they span • A live line marks the current time • Connect multiple Google accounts and see all of them on one timeline • Turn individual calendars on or off • Works inside embedded booking widgets, not just the scheduler's own site • The on-page button shows how many events you have on the selected date ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY Slotcheck has no backend. There are no servers, no database, and no account to create. Your calendar data is requested by your browser directly from Google and stays on your computer in local extension storage. It is never transmitted to us, because there is no "us" to transmit it to. • Read-only calendar access — Slotcheck cannot create, edit, or delete anything • No analytics, telemetry, or third-party scripts • Nothing sold, shared, or used for advertising or model training • Uninstalling removes every trace from your machine Full policy: https://slotcheck.app/privacy ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SUPPORTED SCHEDULERS Calendly · Cal.com · HubSpot Meetings · SavvyCal Both the schedulers' own pages and booking widgets embedded on other websites. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ GETTING STARTED 1.
