Frequently Asked Questions

Everything you need to know about our AI calendar assistant

What is calen?

calen is an AI calendar assistant you control by chatting in plain language. It schedules meetings, reschedules events, finds free time, and manages your calendar across the web, Telegram, and email. calen connects to your Google Calendar and works like a personal chief-of-staff for your time.

How does an AI calendar assistant work?

You tell calen what you want in natural language, for example, "Schedule lunch with Sarah tomorrow at 1 PM" or "Move my 3 PM to next week." calen reads your connected calendar, checks availability, resolves conflicts, makes the change, and confirms it back to you.

Does calen work with Google Calendar?

Yes. calen integrates directly with Google Calendar, so events you create or change sync in real time both ways. Outlook and iCal support are on the roadmap.

Can I use calen on Telegram and email?

Yes. calen is multi-channel: chat with it in the web app, message it on Telegram, or CC it on an email thread to coordinate a meeting. Every channel shares the same assistant and the same calendar access.

How is calen different from Google Calendar or a regular scheduling app?

A regular calendar shows your schedule; calen runs it. Instead of clicking through forms, you ask in plain language and calen books, moves, and finds time for you, proactively. It is an assistant, not just a grid.

Is calen free?

Yes. calen has a free-forever plan with 50 AI requests per month, calendar management, and the email assistant. Pro unlocks unlimited requests and advanced automation. No credit card is required to start.

Is my calendar data private?

calen only accesses the calendars you explicitly connect and uses that access solely to carry out your requests. You can disconnect your calendar at any time from settings.
