Get your wordPress aI agent running in minutes while you optimize your full content strategy

When you need a WordPress AI chatbot up and running today but want to perfect your content indexing strategy over time, IntelliWP’s WordPress AI agent with RAG system using plain text files is your fastest path to success. This comprehensive guide shows you how to train AI on website content and get from zero to functional AI chatbot in under 5 minutes.

Why Start with Plain Text Files?

Unlike traditional WordPress AI solutions that require extensive model training, this RAG WordPress approach with text files offers:

  • Instant deployment – Upload files and start your WordPress AI agent immediately
  • Easy updates – Add or modify content without retraining your AI agent
  • Perfect testing ground – Validate your website AI concept before scaling
  • No technical barriers – Plain text files work

This method represents the best WordPress AI agent plugin approach for rapid deployment while building toward a comprehensive AI website assistant.

Prerequisites (2 minutes)

You’ll need:

  • IntelliWP plugin installed and activated
  • OpenAI API key configured for your WordPress AI agent
  • Basic text files with your key information ready

Quick API setup for your WordPress AI:

  1. Navigate to IntelliWP → Settings in your WordPress admin
  2. Enter your OpenAI API key to power your AI agent for WordPress
  3. Select RAG (Retrieval-Augmented Generation) as your method
  4. Save settings to activate your WordPress agent

Step 1: Prepare Your Text Files (1 minute)

Create simple .txt files with your most important information for your WordPress AI agent training. Each file should focus on one topic to optimize your AI agent for WordPress:

Example structure for effective WordPress AI:

customer-support.txt
- Contact information
- Hours of operation  
- Common policies

product-info.txt
- Key product features
- Pricing information
- URLs
- Use cases

company-info.txt
- About your company
- Mission and values
- Key services

Pro tip: Start with 3-5 files covering your most frequently asked topics. This approach allows you to train WordPress AI agent efficiently while building comprehensive coverage over time.

Step 2: Upload Your Files (30 seconds)

  1. Go to IntelliWP → Files in your WordPress dashboard
  2. Click “Choose Files” or drag-and-drop your text files
  3. Click “Upload Files”

The IntelliWP AI chat plugin for WordPress immediately processes plain text files – no waiting required for your WordPress AI agent to access the content.

Step 3: Configure RAG Settings (1 minute)

Navigate to IntelliWP → RAG Configuration to set up your WordPress AI chatbot with RAG system:

Essential settings for quick start:

  • Include uploaded files: Enabled
  • Include posts and pages: Disabled (for now – focus on files first)
  • Similarity threshold: 0.75 (balanced relevance for AI agent)

Quick indexing for your WordPress AI:

  1. Click “Start Custom Indexing”
  2. Select only “Files” as source
  3. Click “Start Custom Indexing”
  4. Wait 30-60 seconds for your WordPress AI agent processing

Step 4: Test your wordPress AI agent (30 seconds)

  1. Go to IntelliWP → RAG Configuration → Test RAG tab
  2. Enter a question related to your uploaded content
  3. Click “Submit Query”
  4. Review how your WordPress AI agent responds and retrieves documents

If responses seem off: Check the “Retrieved Documents” section to see what content your AI agent for WordPress found. This helps you understand if your files need better organization for optimal WordPress AI agent training.

Step 5: Deploy Your WordPress AI Agent

Your WordPress AI agent is now ready! The system will automatically use your uploaded files to provide AI powered customer support for WordPress websites.

To display your WordPress chatbot:

  • Use the provided shortcode on any page/post
