Building a Slack AI Chatbot with AWS Amazon Bedrock

Introduction

  • Aim: Build an AI chatbot for Slack using AWS Amazon Bedrock.
  • Capabilities:
    • Pulls from 30+ different AI models.
    • Automate processes easily with n8n.
    • Integrates real-time data from knowledge bases.
  • Motivation: Save costs on Slack's AI features by building your own.

Cost Analysis

  • Slack AI chatbot feature cost: ~$10,000/year for 1,000 users.
  • DIY approach is cost-effective, saving over $10k/year.

Tools & Technologies

  • Slack: A communication platform with advanced features.
  • AWS Amazon Bedrock: Provides access to various AI models.
  • n8n: Workflow automation tool to connect services.

Setup Process

Creating Slack Workspace

  1. Sign up and create a Slack workspace.
  2. Configure channels and features needed for the chatbot.

API Integration

  1. AWS Integration:
    • Set up Identity Access Management (IAM) for permissions.
    • Create a user with Bedrock full access.
    • Securely store access keys.
  2. Slack Integration:
    • Create an app and set up OAuth tokens.
    • Add necessary permission scopes for Slack bot interactions.
    • Install app to workspace and configure permissions.

Workflow Automation with n8n

  1. Setting Up n8n:
    • Log into n8n and create a new project.
    • Save AWS and Slack credentials within n8n.
  2. Creating Automations:
    • Use n8n to create automation workflows linking Slack and AWS.
    • Configure webhooks to handle events like app mentions.

Building the Chatbot

Basic Workflow

  1. Event Trigger: Capture app mentions on Slack to trigger workflows.
  2. Data Processing:
    • Use execution data node to capture Slack messages.
    • Process and format message data for AI model input.
  3. AI Model Integration:
    • Select and use models (e.g., CLAUDE V3) from Bedrock.
    • Process input and generate responses using AI models.
  4. Sending Responses:
    • Format and send AI-generated responses back to Slack.

Enhancing with Knowledge Base

  • Knowledge Base Setup:
    • Utilize S3 buckets or other data sources for real-time information.
    • Sync data with AWS Bedrock to enhance AI model responses.
  • Improved Responses:
    • Use additional real-time data to refine and provide accurate AI responses.

Conclusion

  • The DIY Slack AI chatbot is cost-effective and leverages powerful AI models.
