About
CalStack is a booking tool for Google Workspace that handles every sales or client call before, during, and after.
Before the call: leads answer a few questions when they book, and AI turns their answers into talking points with suggested timing. Bookings only use free slots from your Google Calendar.
During the call: a side panel inside Google Meet shows your agenda and the lead's answers, so you never go in cold.
After the call: tag the outcome (Won, Follow-up, Not a fit, or your own), add notes, and AI drafts a recap with one clear next step. Push everything to Gmail, Slack, Google Sheets, Zapier, or n8n.
Built for agencies managing booking pages for multiple clients, marketing teams turning ad clicks into booked calls, and sales/CS teams running demos and onboarding.
There's a free plan (no credit card): 3 booking pages, 20 AI credits a month, and the Google Meet add-on. I'd love your feedback!
