Quick Summary

This workflow connects Telegram, Google Gemini AI, and Notion to make task creation effortless.

Whenever you send a message to your Telegram bot, Gemini AI reads your message, understands what task you meant, and automatically creates it in your Notion database - complete with the task name and due date.

If you approve, the task is added to Notion and you’ll get a confirmation in Telegram.
If you decline, it simply replies that ❌ no task was created.

Perfect for anyone who wants to capture ideas or to-dos directly from Telegram without opening Notion every time.

Detailed Use Cases

  1. Quick task capture from Telegram

    • Send a message like “Buy milk 25 May” to your Telegram bot.
    • The AI extracts the task name and date, asks you to approve, and creates a Notion task once approved.

  2. Turn reminders into Notion tasks

    • Message: “Pay rent next Monday” → Approve → Task added to Notion with the correct due date.
    • Perfect for quickly saving reminders while on the go.

Tip: For best results, include clear dates in your messages like 25 May or May 25, 2025 so the AI can extract them accurately.

Prerequisites / Requirements

Before using this workflow, make sure you have the following ready:

  1. Telegram Bot Setup

    • Go to @BotFather on Telegram.
    • Create a new bot using the /newbot command.
    • Copy the Bot Token — you’ll need it to connect in the Telegram Trigger and Telegram nodes in n8n.

  2. Google Gemini API Key

    • Sign up for a free Google AI Studio account.
    • Create an API key and connect it in your n8n credentials under Google Gemini.
    • This workflow uses the models/gemini-2.5-flash-lite model, which works perfectly on the free tier.

  3. Notion Database Setup

    • Create a Notion database for storing tasks.
    • It must have:
      • A Title property — set this as the Task Name (type: Title / text).
      • A Date property — set this as the Due Date (type: Date).
    • Copy your Notion database ID and connect your Notion API credentials in n8n.

  4. Optional Security Note

    • In the Telegram Trigger node, restrict the chatId to your own Telegram user ID if this workflow is for personal use.

Customization Guide

You can easily extend this workflow to capture more details from your Telegram messages using the AI Extract node.
Here are a few simple ways to customize it:

  1. Add more extracted fields

    • In the AI Extract: TaskName & TaskDue node, open the Attributes section.
    • Add new fields like:
      • Priority → text (e.g., High, Medium, Low)
      • Duration → number or text (e.g., 30 mins, 1 hour)
      • Notes → text (optional extra info)
    • The Gemini model will automatically try to extract these from your message.

  2. Example messages you can send

    • “Finish report by Friday — high priority, 2 hours.”
    • “Workout tomorrow evening — medium priority.”

  3. Map extra fields to Notion

    • In the Notion: Create Task (Page) node, scroll to the Properties section.
    • Add matching Notion properties for each new field (e.g., Priority, Duration).
    • Map the AI outputs (like output.Priority) to their respective fields.

  4. Send confirmation with extra data

    • In the Send and Wait for Response (Approve/Decline) node, include the new extracted details in the Telegram message before approval.
    • Example confirmation message:
      Task: {{ $json.output.TaskName }}
Due: {{ $json.output.TaskDue }}
Priority: {{ $json.output.Priority }}
Duration: {{ $json.output.Duration }}

By doing this, you can build a smarter task capture system that includes priority, time estimation, and other useful details, all directly from your Telegram chat.
