More Than a Calendar — Your AI Travel Logistics Partner

Smart Calendar is an AI-powered scheduling app that goes beyond simple event management. It intelligently plans travel logistics between events, handles multi-timezone scheduling, and manages multiple calendar views simultaneously.

Create unlimited calendars for different trips or projects, let AI fill transportation gaps between events, and track costs across multiple currencies — all while keeping your data completely private on your device.

Key Features

AI Gap Filling & Logistics

AI analyzes your schedule and automatically plans realistic transportation between events. Understands flights, trains, transfers, and 'last mile' connections with proper timing for real-world travel.

Multi-timezone support with automatic conversion, weather forecasting for event locations, and live currency exchange rates across 10 currencies with overcharge warnings.

Smart Event Management

Handle overnight events, simultaneous overlapping events with column display, and timeline optimization. Includes Google Maps integration and Google Calendar export.

Real-World Transportation

AI understands airport transfers, train connections, bus terminals, and customs timing. Plans feasible journeys and warns about impossible connections with alternative suggestions.

Frequently Asked Questions

How does AI gap filling work?

AI analyzes the time and distance between consecutive events on your calendar and automatically suggests realistic transportation options. It understands airport transfer times, train connections, and 'last mile' logistics to ensure feasible travel plans.

Can I work with multiple calendars simultaneously?

Yes. You can create unlimited calendars, view multiple calendars at once with independent visibility controls, and duplicate entire calendars to compare different trip scenarios. AI operates on your currently selected calendar for focused planning.

How does timezone handling work?

All events are stored with their specific timezones and automatically converted to your selected home timezone for display. You'll see clear day offset indicators (+1d/-1d) when events occur on different days in different timezones.

What export formats are supported?

You can export calendars as iCalendar (.ics) files for importing into other calendar apps, JSON for data backup, Markdown for human-readable sharing, or directly to Google Calendar with one-click event creation.

How does currency and cost tracking work?

The app supports 10 major currencies with hourly updated exchange rates. It shows costs in both your home currency and local destination currency, with expected price ranges and overcharge warnings for typical expenses.

Is my calendar data stored in the cloud?

No. All calendar data is stored locally in your browser's IndexedDB. There's no cloud sync, account creation, or data upload. Only AI trip planning requests (with timing/location only) and live currency rates require internet access.
