Steps

1. Create Telegram bot and configure trigger

   Create a bot via @BotFather in Telegram and obtain the Bot Token. In n8n, open the template, locate the 'Listen for incoming events' node, select Telegram Trigger type, and paste the Bot Token to complete credential setup. The trigger listens for 'message' updates.

2. Add OpenAI API key

   Add an openAiApi credential in n8n's credential manager with your OpenAI API key. This key is used by both the 'Transcribe a recording' node for voice-to-text and the 'OpenAI Chat Model' node for AI agent reasoning.

3. Connect Notion and update page URL

   Add a notionApi credential in n8n and complete Notion authorization. Open the 'Create a page in Notion' node and update the pageId to your Notion to-do list page or database URL.

4. Configure AI assistant system prompt

   Open the 'Tard, AI Assistant' node and configure the following system message in Options > System Message. This prompt defines the assistant's name, scope, Notion guidelines, and behavior rules. n8n $fromAI override: ``` ={{ /*n8n-auto-generated-fromAI-override*/ $fromAI('Search_Text', ``, 'string') }} ```

   Copy prompt

   =You are my personal assistant. Your name is Tard.
   
   Today’s date is:
   {{ $today.format('yyyy-MM-dd') }}
   
   Scope of responsibility:
   You work exclusively with Notion.
   
   Your main focus:
   Managing and reading a Todo List.
   
   You work with pages, tasks, and data stored in Notion only.
   You do NOT have access to email or calendars and must ignore them completely.
   
   Notion guidelines:
   - When presenting tasks, filter and show only what is relevant to the request
   - If no date is specified, assume the user means today
   - Be clear, short, and well structured
   - Do not invent information that does not exist in Notion
   - Always include a Notion link when answering questions about Notion content
   
   General questions:
   You may also answer general AI questions not related to Notion, such as:
   - History
   - Nutrition (e.g. calories in food)
   - General knowledge
   - Simple explanations of various topics
   
   Behavior rules:
   - Use a natural, informal tone
   - Be helpful, focused, and not verbose

5. (Optional) Enable Gmail or Google Calendar extensions

   To extend functionality, enable the 'Get Email', 'Send Email', and 'Google Calendar' nodes (disabled by default) and configure their credentials. Note: the AI assistant's system prompt instructs it to ignore email and calendars; update the prompt if enabling these.

6. Activate workflow and start using via Telegram

   Save and activate the workflow. Send text or voice messages to your bot in Telegram: text messages go directly to the AI agent; voice messages are first transcribed to text via OpenAI. The AI agent uses short-term conversation memory (Window Buffer Memory) to understand intent, calls Notion tools to search or create tasks, and replies to Telegram in Markdown format.
