Create or view a calendar event in 10–15 seconds

About the project

A personal AI assistant that creates events in Google Calendar and keeps time records in Google Sheets. Instead of filling in forms, you send a text or voice message, and the system works out what needs to be done.

“Tomorrow from 9 to 10 — meeting with the client” becomes a calendar event. “Worked two hours on the Website project” becomes a structured work record. AI extracts dates, duration and the project name, and if a request is unclear, it asks for clarification.

The assistant also shows events on request and sends a summary of upcoming tasks to Telegram every evening.

How it works

  1. Message in Telegram
  2. Speech recognition and intent detection
  3. Calendar event or time-log entry
  4. Reply in the chat

Features

  • Planning in natural language. Understands phrases like “tomorrow morning”, “in two days”, “from 9 to 1” and takes the time zone into account.

  • Time tracking without filling in a table by hand. Saves the date, category, project, work description and duration.

  • Consistent project names. Maps colloquial names to the accepted ones and corrects recognition errors in them.

  • Schedule overview. Lists events on request and sends a daily summary automatically.

  • Color labels for events. Highlights separate categories, for example urgent tasks.

  • Clarifying unclear requests. Helps clarify the intent before choosing an action.

Where it can be used

  • Personal planning for managers and specialists.
  • Tracking project work for freelancers and consultants.
  • Organizing meetings and logging labor costs in a small business.

This approach can be adapted to the work categories and planning rules of a specific organization.
