We built CalenSync because we were tired of missing things.
The Inbox and the Calendar were never meant to be enemies. But while calendars require active management, inboxes are passive catch-alls. CalenSync pulls it all together so nothing slips through.
Privacy Is Not a Feature — It's the Foundation
We designed CalenSync with read-only access from day one. We cannot send emails from your accounts. We cannot delete your calendar events. Your emails are processed in memory by our AI and never stored or used for training. Your data is yours.
AI Should Work Quietly in the Background
Our AI doesn't need you to learn prompts or configure workflows. It reads your emails, classifies what matters, assigns a confidence score, and only surfaces events it's highly confident about. You see the results, not the machinery.
How It Works
A seamless flow from connection to intelligence.
Connect your accounts
Link multiple Google accounts in a few clicks. Your active session stays untouched.
We read, you don't have to
CalenSync continuously scans your inboxes and intelligently extracts events from your emails.
Everything in one place
Calendar events, email-detected events, and upcoming deadlines appear on a single, filterable timeline.
Stay ahead, not behind
Our AI Insights dashboard analyzes your upcoming week, flags conflicts, and highlights tight transitions.
Built For People Who Juggle
Designed for those who manage multiple lives in a single day.
Freelancers & Consultants
Managing multiple client emails shouldn't mean managing multiple calendars. CalenSync unifies them.
Founders & Executives
Get an executive-level summary of your personal and professional commitments in one view, with AI-powered conflict detection.
Frequent Travelers
Confirmation emails become structured itinerary events automatically. No more digging through your inbox at the airport gate.
Security You Don't Have to Think About
We request only read-only permissions — CalenSync cannot send emails or modify your calendar. All tokens are encrypted, and email content is processed in memory without being stored.
We built the infrastructure we'd trust with our own inboxes — because we do.
What's Next
CalenSync launched with deep Google integration — but your digital life doesn't stop there. We're building integrations with Microsoft Outlook, Office 365, and a growing list of productivity and travel platforms.
A dedicated mobile app, real-time conflict alerts, and two-way calendar sync are also on the way. Wherever your events live, CalenSync will find them.
