Under the hood
The calendar that can't double-book.
Most schedulers prevent conflicts in application code — and fail under race conditions. Callilio enforces it in Postgres itself, with exclusion constraints. Two calls booking the same slot at the same second: one wins, one gets the next opening. Always.
Database-level locks
Overlaps are blocked by Postgres exclusion constraints — not by hopeful app logic.
Back-to-back friendly
10:00–11:00 and 11:00–12:00 never collide. Half-open time ranges, by design.
Cancel = instant slot
A cancelled booking frees its slot the same second — the next caller can take it.
Recurring built in
Weekly clients, standing reservations — RFC 5545 recurrence, conflict-checked per occurrence.
Two-way calendar sync
Google Calendar and Outlook, connected per staff member. Their busy time is your AI's busy time.
Timezone-correct
Every booking is stored timezone-aware — daylight saving handled by the database, not by luck.
Multilingual out of the box
Every caller feels right at home.
Callilio speaks 19 languages with automatic detection. If a caller switches mid-call, a native-speaking colleague takes over — same call, same context.
