How It Works
How It Works Telegram Trigger → Sub-Workflow (Separate Text/Files) → IF (Is PDF?) ├── True: Extract PDF → Set Text → Code (Clean) → Done! └── False: NoOp (Ignore) 9 nodes**: Lightweight, efficient (no loops). Key Steps**: Triggers on Telegram messages - downloads files. Sub-workflow splits text/files. (Optional but recommended) IF node checks MIME type/extension for PDFs. Extracts text via "Extract From File" node. AI writes summary. Responds to user. Setup Instructions IMPORTANT* : Requiring an n8n instance to be configured with public/production webhook ! Recommendation: Ngrok or Cloudflare Tunnel Add the Telegram credential Go to Credentials → New Credential → Telegram API. Paste your Bot Token. Configure the Trigger Open the Telegram Trigger node. Ensure Trigger On contains Message. Enable Download under Additional Fields so file payloads are attached to the node output. (Optional) Enable the sub‑workflow Automate Telegram Message Processing - Separate Text and Files 💬📁 If you need both message text and attachments, enable the Automate Telegram Message Processing – Separate Text and Files node and import the referenced workflow into your workspace. Deploy the workflow and activate it. Testing Send a message with a PDF attachment to your Telegram bot. There will be a response from the chat that summarizes the PDF content. Nodes Used Telegram Trigger**: Listens for incoming messages and downloads attachments. Execute Workflow**: Calls a sub-workflow to separate text and file data (recommended for reliable file handling). If**: Checks MIME type to ensure the file is a PDF. Extract From File**: Converts the PDF binary into text. Set**: Assignments to organize the text data. Code**: Cleans the text (removes excess newlines) to prepare it for the LLM. Basic LLM Chain**: Orchestrates the AI prompt and processing. AI Chat Model**: The specific LLM provider used for high-speed inference. Telegram**: Sends the final summary back to the user. Output Example The bot will reply with a message formatted like this: > Title: Q3 Financial Report > Type: Financial Report > Exec Summary: Revenue increased by 15% due to new product lines... > Key Insights: > • Growth in APAC region. > • Reduced operational costs by 5%. 🙏 Thank You for Trying This Workflow!
