Inspiration

People in group chats or clubs often see important dates(club announcements, school events, deadlines, meeting details) shared through messages, posters, or forwarded publicity texts. But because there is no automatic bridge between chats and calenders, most forget to manually transfer them to their calendar. This leads to missed deadlines, lost opportunities, and messy coordination.

What it does

Karen - telegram bot streamlines this process. By simply sending or pasting any event-related text (like a publicity message or announcement) to the bot, it automatically extracts the event name, date, and time, then adds it to your calendar instantly. The bot supports: • Smart text parsing: Paste any event announcement and the bot identifies key info (event name, date, time). • Command-based input: Manually add or delete events with natural language prompts (e.g. “Add meeting with John on Feb 13, 3–4 PM”). • Range handling: Supports start and end dates for multi-day events. • Deletion: Remove events easily through structured text commands.
