AI-Powered HR & IT Helpdesk Chatbot for Telegram

Unlock Instant Employee Support with this AI Agent

This AI Agent transforms your internal HR and IT support by creating an intelligent chatbot accessible via Telegram. It ingests your company's policy documents (e.g., employee handbooks, IT guides in PDF format), building a comprehensive knowledge base. Employees can then ask questions in natural language, including voice messages, and receive instant, accurate answers.

This AI Agent's core abilities include:

• Document Intelligence: Extracts and understands information from your PDF documents.
• Knowledge Base Creation: Uses OpenAI embeddings and a PostgreSQL PGVector store to create a searchable knowledge base.
• Audio Transcription: Transcribes voice messages from Telegram users into text using OpenAI Whisper.
• Conversational AI: Leverages OpenAI's powerful language models for natural and contextual interactions.
• Retrieval Augmented Generation (RAG): Provides answers grounded in your specific documents, ensuring relevance and accuracy.

• An n8n instance (Cloud or self-hosted).
• OpenAI API Key with access to:
  • Embedding models (e.g., text-embedding-ada-002 or newer).
  • Chat completion models (e.g., gpt-3.5-turbo, gpt-4).
  • Audio transcription models (e.g., whisper-1).
• Telegram Bot API Token created via BotFather.
• PostgreSQL database credentials. The database must have the PGVector extension enabled.

1. Download the n8n workflow JSON file (ai-hr-it-helpdesk-chatbot-v1.0.0.json).
2. Import the workflow into your n8n instance.
3. Configure Credentials:
   • Update all OpenAI nodes ('Embeddings OpenAI', 'OpenAI' for transcription, 'OpenAI Chat Model') with your OpenAI API Key.
   • Update all PostgreSQL nodes ('Create HR Policies', 'Postgres Chat Memory', 'Postgres PGVector Store') with your PostgreSQL credentials.
   • Configure the 'Telegram Trigger' and 'Telegram' (send message) nodes with your Telegram Bot API Token.
4. Initial Knowledge Base Setup:
   • In the 'HTTP Request' node, change the url parameter to the direct download link of your internal policy PDF document.
   • Manually execute the workflow starting from the 'When clicking ‘Test workflow’' node. This will download the document, extract its text, create embeddings, and store them in your PostgreSQL vector store. This step only needs to be run once initially, or when your policy documents change.
5. Customize AI Agent (Optional):
   • Review and adjust the systemMessage in the 'AI Agent' node (e.g., "You are a helpful assistant for HR and employee policies") to better suit your company's tone and specific domain.
   • Modify the 'Answer questions with a vector store' tool's name and description if desired.
6. Activate the workflow.
7. Test by sending text and voice messages to your Telegram bot.
