How it works
Before the call
Show up knowing exactly what to say.
Leads answer your questions when they book, and AI turns their answers into a ready-to-run agenda.
- AI-built booking flows with branching questions
- Books only real free slots in Google Calendar
- Talking points with suggested minutes
During the call
Stay on track without switching tabs.
A side panel inside Google Meet keeps your agenda and the lead's answers right next to the conversation.
- Talking points and lead answers in one panel
- Runs inside Google Meet, no extra window
- Tag the outcome before you hang up
Available on Google Workspace Marketplace(opens in a new tab)After the call
Turn every call into a clear next step.
Tag how it went, add a few notes, and AI writes the recap for you.
- Outcome tags: Won, Follow-up, Not a fit, or your own
- AI recap and one next step
- Connects to Zapier and Gmail

- Their answers beside you in Google Meet
- Outcome tags and notes after every demo
Book sessions without the back-and-forth.
Share one link and let clients pick a time. The Meet link and your prep are ready when they arrive.
- Hosted booking page, no website needed
- Google Meet link on every booking, automatically
- Session notes turned into a short recap
Works with your tools.
Calendar and Meet are built in. Every booking can also go to the tools your team already uses, with the lead's answers included.
Google Calendar connects through a verified Google OAuth app. CalStack sees your free/busy times and only the events it creates.
Email or chat. Send an email from Gmail, or post in a Slack channel or a Google Chat space.
Keep a record. Add each booking as a row in Google Sheets.
Run your own flow. Start a Zapier, n8n or webhook workflow when a booking is made, moved or cancelled.
Security and privacy, in plain words.
You're connecting your calendar and your leads' answers. Here's what CalStack does with them.
Hosted in the EU.
Your account, booking pages and bookings are stored on AWS in Stockholm, Sweden, and the app runs in the same region. Sign-in (Clerk) and AI features (OpenAI) use US providers, listed in our privacy policy.
Only the Google access bookings need.
For your calendar, CalStack reads free/busy times and manages only the events it creates. Gmail is send-only: we never read your inbox. Other Google tools stay off until you connect them.
Google's Limited Use rules.
Data from Google APIs is handled under the Google API Services User Data Policy, including the Limited Use requirements. It's never sent to an AI provider.
Not sold. Not used to train AI.
We don't sell your data or your leads' data. We don't train AI models on it, and OpenAI doesn't train on data sent through its API.
Calls aren't recorded.
CalStack doesn't record or transcribe your calls. Recaps are written from the notes you type.
Leave anytime, data included.
Disconnect any integration in one click and its Google access is deleted. Delete your account and your data goes with it.
Wherever you live, you can ask for a copy of your data, a correction, or deletion, as GDPR and CCPA provide.
Hi, I'm Hamza. I build CalStack.
I taught myself to code, freelanced for two years, then spent about three years at Elevate A/B Testing, a US company that builds A/B testing software for Shopify stores. My job there was conversion: finding out why visitors leave, and what makes them act.
CalStack is that work applied to sales calls. The questions before the calendar, the prep before the call, the recap after: each step is there to turn a visitor into a booked, qualified call.
I work on CalStack full-time from Fes, Morocco, and I read every email myself.
