Make Your Availability Visible and Bookable
Every morning, a Telegram message lists your open slots for the day: "Available 10-11 AM, 2-3 PM, 4-5 PM." People can see this and book directly instead of asking "Are you free?" fifty times.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Send Message
Send a text message to a telegram chat using the bot api.
Why this helps
People constantly ask "Are you available Thursday at 2?" You have to check your calendar every time. A stream of individual availability questions wastes mental energy that could go to actual work.
- Stop fielding availability questions; show open slots automatically
- Make it easy for people to see when they can book time with you
- Reduce the back-and-forth of finding a common meeting time
- Free up mental energy by making availability transparent
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Telegram to Notis.
- 2Create an automation: "Every morning at 8 AM, send a Telegram message listing all my open meeting slots for the day."
- 3Select the trigger: "Notis Cron" with a daily morning schedule.
- 4Tell Notis to exclude personal time blocks or focus only on meeting-available slots.
- 5Choose your Telegram channel or public group as the destination.
Questions about this workflow
How long should the available slots be?
Tell Notis your preferred meeting length (30 min, 1 hour) and it'll calculate available blocks accordingly.
What if I have no availability?
Notis sends a message like "Fully booked today" so people know not to ask.
Can I exclude certain types of time blocks?
Yes. Tell Notis to only announce slots outside focus time, lunch, or other buffers.
