Watch the video

Empower employees to instantly access and understand the company’s Code of Conduct via a Slack chatbot, powered by Retrieval-Augmented Generation (RAG) and LLMs.

🧑‍💼 Who’s it for

This workflow is designed for:

  • HR and compliance teams to automate policy-related inquiries
  • Employees who want quick answers to Code of Conduct questions directly inside Slack
  • Startups or enterprises that need internal compliance self-service tools powered by AI

⚙️ How it works / What it does

This RAG-powered Slack chatbot answers user questions based on your uploaded Code of Conduct PDF using GPT-4 and embedded document chunks. Here's the flow:

  1. Receive Message from Slack: A webhook triggers when a message is posted in Slack.
  2. Check if it’s a valid query: Filters out non-user messages (e.g., bot mentions).
  3. Run Agent with RAG:
    • Uses GPT-4 with Query Data Tool to retrieve relevant document chunks.
    • Returns a well-formatted, context-aware answer.
  4. Send Response to Slack: Fetches user info and posts the answer back in the same channel.
  5. Document Upload Flow:
    • HR can upload the PDF Code of Conduct file.
    • It’s parsed, chunked, embedded using OpenAI, and stored for future query retrieval.
    • A backup copy is saved to Google Drive.

🛠️ How to set up

  1. Prepare your environment:

  2. Upload the Code of Conduct PDF:

  3. Deploy the chatbot:

    • Host the webhook and connect it to your Slack app.
    • Share the command format with employees (e.g., @CodeBot Can I accept gifts from partners?)
  4. Monitor and iterate:

    • Improve chunk size or embed model if queries aren’t accurate.
    • Review unanswered queries to enhance coverage.
