Steps

1. Configure Telegram trigger and message router

   After importing the template into n8n, configure the Telegram Trigger node: create a bot via @BotFather and obtain the token, enter it as the telegramApi credential; set additionalFields.chatIds to your Telegram user ID; set download = true to support voice messages. Configure the Text vs Voice Router (If node): condition checks whether $json.message.text exists — if yes, route to text path; if not (voice message), route to voice branch. This node also triggers Get memories in parallel to fetch historical context.

2. Configure voice transcription branch (optional)

   If the user sends a voice message, the flow routes to Get a file to download the voice file (fileId = $json.message.voice.file_id), then to Transcribe a recording (OpenAI audio transcribe operation) to convert speech to text before merging into the Agent input. Text messages bypass this branch and go directly to Merge.

3. Configure memory system

   Long-term memory: create an Airtable base/table with fields Memory, User, and Created (auto-managed). In the Get memories node, set the base/table ID and filterByFormula (e.g., {User} = 'your_name'). The Aggregate node packs Memory and Created into a Memories array. The Merge node combines current input with Memories before sending to the Agent. Short-term memory: in Simple Memory, set sessionKey = {{ $('If').item.json.message.chat.id }} and contextWindowLength = 30 (adjustable). The Save Memory tool node uses the same base/table, with User hardcoded or mapped and Memory using $fromAI('Memory').

4. Connect tools and credentials

   Create and link credentials for each tool: xAI Grok Chat Model (model: grok-4-0709, credential: xAiApi); Search Web with SerpAPI (serpApi); Google Calendar tools (googleCalendarOAuth2Api): Get many events / Create / Update / Delete; Gmail tools (gmailOAuth2): Get many messages / Get a message; Notion tool (notionApi): Get a database, databaseId required; Save Memory (airtableTokenApi). All tools connect to the AI Agent via ai_tool links.

5. Configure AI Agent system prompt and input

   In the AI Agent node, set promptType = define. For Text input, use the expression: ={{ $json.text }}{{ $json.message.text }} (merges transcribed text with original text). Enter the following system prompt (replace ____ with your actual info):

   Execution prompt · Source text。AI Agent node System Message field

   Copy prompt

   =# ROLE  
   You are a friendly AI assistant.  
   You are talking to ____. Your name is ____, your gender is ____.
   
   # RULES  
   When the user sends a new message, determine whether it contains information that should be saved in memory. Keep in mind that almost everything needs to be saved, as every detail is important to the user. Call the **Save Memory** tool to save the information. DO NOT inform the user that the information has been saved. Just continue to answer the question or perform the next tasks.  
   Do not use emojis, only in cases where it is truly appropriate.
   
   # Tools  
   ## Save Memory  
   Use this tool to save information about the user. Extract and briefly summarize the details from the user's message and pass them to this tool.  
   ## SerpAPI  
   Use this tool if you need to find something on the Internet.  
   ## Google Calendar  
   These are several tools to be used if the user requests something related to the calendar and schedule.  
   ## Gmail  
   These are several tools to be used if the user requests something related to email and messages.  
   ## Notion  
   These are several tools to be used if the user requests something related to Notion, Neurocracy, or reading lists.
   
   # Memory  
   Below are the latest significant memories collected about the user, including the date and time they were created.  
   !! IMPORTANT!  
   Think through your responses and consider the user's preferences!  
   Also, keep in mind the date and time when the memory was saved to always have the most up-to-date information.
   
   {{ $json.Memories.toJsonString() }}

6. Configure Telegram reply and test

   In Send a text message, set chatId = {{ $('Telegram Trigger').item.json.message.chat.id }}, text = {{ $json.output }}, appendAttribution = false. Save and activate the workflow. Test by sending text or voice messages to your bot in Telegram. Verify: text messages get direct replies; voice messages are transcribed then replied; calendar/email/search/Notion queries trigger the corresponding tools; personal facts are silently saved to Airtable.

You are an n8n template setup assistant. The user wants to replicate the 'Telegram Multi-Tool Personal Assistant' template. First confirm whether the user already has: an n8n instance, Telegram bot token and user ID, xAI Grok API key, OpenAI API key, Airtable base/table, Google OAuth (Calendar + Gmail), Notion integration token, and SerpAPI key. If any are missing, provide acquisition guidance. Then guide step-by-step through importing workflow.json, configuring each node's credentials, replacing placeholders in the system prompt, and suggest testing with text first, then voice and tool calls.
