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.

Yes. calen has a free-forever plan with 50 AI requests per month, calendar management, and 10 email assistant credits. Pro raises that to 1,000 AI requests and 1,000 email credits per month, plus executive assistant features. 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.

Manage Your Google Calendar From Telegram

Most calendar edits are small: push a meeting 30 minutes, check what is on tomorrow morning, block an hour for deep work. Opening a calendar app, finding the right day, and dragging boxes around is a lot of interface for a one-sentence request. If you live in Telegram, there is a shorter path.

Chat with your calendar

Connect calen to Telegram and your calendar becomes a chat contact. You write requests the way you would text a person, and the assistant reads your Google Calendar, makes the change, and confirms it back in the same conversation.

"What does my Thursday look like?"
"Move my 3 PM with Dana to Friday morning."
"Block 9 to 11 tomorrow for writing."
"Schedule lunch with Alex next Tuesday at noon."
"Cancel my Friday afternoon meetings."

There is no command syntax to memorize. The assistant handles ambiguity the way a human would: if "next Tuesday" could mean two dates or two people named Alex are in your contacts, it asks instead of guessing.

One assistant, every channel

The Telegram bot is not a separate product. It is the same assistant you get in the calen web app and on email, with the same memory and the same calendar access. Ask for a meeting on Telegram during your commute, and the confirmed event is already on your calendar when you open the web dashboard at your desk.

Why chat beats an app for quick edits

Speed. A one-line message is faster than navigating week view on a phone screen.
No context switch. If a plan changes mid-conversation with a friend, you fix your calendar two taps away, in the same app.
Real-time accuracy. calen syncs with Google Calendar in real time, so the assistant always answers from the current state of your schedule, including events other people just added.

Setup takes two minutes

Sign up for calen, connect your Google Calendar, and link Telegram from the dashboard. The free plan includes 50 AI requests per month, which covers a lot of "move my 3 PM" moments.
