I Built an AI-Powered Reminder App for Telegram

In today’s fast-paced digital world, managing reminders efficiently is essential to stay productive. To address this, I developed an AI-based Reminder App integrated with Telegram that converts natural language commands into actionable reminders intelligently.

🔹 What Makes This App Unique?

This is not just any reminder bot—it is powered by GPT-5-nano from OpenAI, a cutting-edge language model optimized for small footprint and fast performance while providing powerful natural language understanding.

Core Capabilities:

Convert natural language inputs into structured reminders automatically.
Understand flexible input patterns without strict format enforcement.

🔹 How It Works

Users simply interact with the bot on Telegram using commands like:
