Wendell's Diary Technical Outline

Below is a comprehensive technical outline for Wendell's Diary. This outline includes the full process—from blog indexing and ChatGPT API integration to the WordPress one‑page site and a chat bubble interface with Patreon authentication that serves as the digital twin’s user interface.


1. Overall System Architecture

A. WordPress One‑Page Frontend

  • Site Content:
    • A single-page design (wendellsdiary.com) featuring your philosophy, love letters, mythology stories, and lyre music.
  • Chat Bubble Interface:
    • A persistent chat bubble located in the bottom right corner.
    • On click:
      • Unauthenticated Users: Redirect to Patreon for signup/login.
      • Authenticated Users: Open an overlay chat window to interact with your digital twin.

B. Backend API

  • Purpose:
    • Handle user queries, process context from your blog content, and interact with the ChatGPT API.
  • Responsibilities:
    • Verify Patreon authentication (via tokens/sessions passed from WordPress).
    • Retrieve relevant blog post context via vector similarity search.
    • Construct and send prompts to the ChatGPT API.
    • Return chatbot responses to the frontend.

C. Knowledge Base & Indexing

  • Blog Post Ingestion:
    • Automatically fetch posts from your Blogger (wendellsdiary.blogspot.com) using the RSS feed or Blogger API.
  • Embedding Process:
    • Generate vector embeddings using OpenAI’s Embeddings API.
  • Storage:
    • Save vectors and metadata (dates, URLs) in a vector database (e.g., Pinecone, Weaviate, or FAISS) to support semantic search.

D. Patreon Authentication

  • Integration:
    • Use a WordPress Patreon plugin (or a custom OAuth solution using libraries like Passport.js) to enforce access control.
  • Workflow:
    • The chat bubble click triggers a check on the user’s Patreon authentication state.
    • If unauthenticated, users are redirected to complete the OAuth flow.
    • Once authenticated, the session/token is passed to the backend API for verification.

2. Detailed Technical Components

A. ChatGPT API Integration

  • API Calls & Prompt Engineering:
    • Define a system prompt that mirrors your tone, style, and philosophical approach.
    • Dynamically insert contextual excerpts (with blog post links) from the indexed content.
    • Prioritize recent posts via weighting or sorting based on publication date.

B. Knowledge Base from Blog

  • Data Retrieval:
    • Use the Blogger API or RSS feed (e.g., https://wendellsdiary.blogspot.com/feeds/posts/default?alt=rss) to fetch posts.
  • Processing & Embedding:
    • Extract text and metadata from each post.
    • Generate vector embeddings via OpenAI’s API.
  • Storage & Search:
    • Store embeddings and metadata in a vector database.
    • On receiving a query, embed the query and perform a vector similarity search to retrieve the most relevant content.

C. WordPress Integration & Chat Interface

  • Embedding the Chatbot:
    • Develop a custom JavaScript/React chat widget embedded via a WordPress plugin or shortcode.
  • Chat Bubble Functionality:
    • Default State:
      • A small, clickable chat bubble in the bottom right of the page.
    • On Click:
      • Check Authentication:
        • If the user is not logged in via Patreon, redirect them to the Patreon OAuth/login page.
        • If the user is authenticated, open an overlay chat window for interaction.
  • User Experience Enhancements:
    • Loading indicators, error handling, and smooth transitions between authentication and chat window display.

D. Digital Twin Chatbot User Interface Workflow

  • Step 1:
    • User clicks chat bubble.
  • Step 2:
    • Authentication Check:
      • Check if a valid Patreon session/token exists.
  • Step 3:
    • Conditional Flow:
      • If Unauthenticated:
        • Redirect to Patreon for signup/login.
      • If Authenticated:
        • Open the chat overlay.
  • Step 4:
    • Chat Session:
      • The chat widget sends queries to the backend.
      • The backend processes the query (adds context from your blog) and calls the ChatGPT API.
      • Responses are displayed in the chat interface with clickable links back to your blog posts.

E. Patreon Authentication Integration

  • WordPress OAuth Setup:
    • Install and configure a Patreon WordPress plugin (or implement a custom solution).
  • Session & Token Management:
    • On successful OAuth login, store user session details or access tokens.
    • Backend API validates these tokens before processing any chatbot requests.
  • Access Control:
    • Ensure that only Patreon-authenticated users can access the digital twin chat functionality.

F. Backend API Implementation

  • Framework & Language:
    • Built using Node.js (Express) or Python (Flask/FastAPI) for flexibility.
  • Endpoints:
    • Authentication Middleware:
      • Check for valid Patreon tokens/sessions.
    • Query Handling Endpoint:
      • Receive user queries, fetch context, construct prompts, and call the ChatGPT API.
  • Integration with WordPress:
    • Communicate via AJAX/Fetch from the frontend chat widget.

3. Step-by-Step Implementation Guide

Step 1: Build the Blog Indexing Pipeline

  • Data Extraction:
    • Write a script (Python/Node.js) to fetch blog posts via the Blogger API or RSS feed.
  • Data Processing:
    • Extract content, publication date, and URL from each post.
  • Embedding Generation:
    • Use OpenAI’s Embeddings API to create vector representations.
  • Storage & Automation:
    • Save embeddings and metadata in the chosen vector database.
    • Automate the indexing process using cron jobs or serverless functions (e.g., AWS Lambda).

Step 2: Develop the Backend API

  • Server Setup:
    • Initialize your project using Node.js (Express) or Python (Flask/FastAPI).
  • Authentication Middleware:
    • Implement middleware to verify Patreon tokens or session data.
  • Query Handling:
    • Embed user queries and perform vector similarity search.
    • Retrieve relevant blog context and construct a ChatGPT prompt.
  • API Call:
    • Send the prompt to the ChatGPT API and return the response to the frontend.

Step 3: Implement Patreon Authentication in WordPress

  • Plugin Installation:
    • Install and configure a Patreon WordPress plugin.
  • OAuth Flow:
    • Set up the OAuth flow to handle user signup/login via Patreon.
  • Token Management:
    • Store and validate tokens or session data for backend API verification.

Step 4: Develop the Frontend Chat Interface on WordPress

  • Chat Widget Creation:
    • Build the chat bubble UI using HTML/CSS/JavaScript or React.
  • Event Handling:
    • On click, check the user’s authentication state:
      • If unauthenticated: Redirect to Patreon.
      • If authenticated: Open the chat overlay.
  • API Integration:
    • Use AJAX/Fetch to send queries from the chat interface to the backend API.
  • User Experience:
    • Incorporate smooth animations, loading indicators, and error messaging.

Step 5: Testing and Deployment

  • Local Testing:
    • Test blog indexing, backend API, authentication flow, and the chat interface locally.
  • Integration Testing:
    • Validate the complete workflow: from clicking the chat bubble and authentication to receiving ChatGPT responses.
  • Deployment:
    • Deploy the backend API on a cloud provider (AWS, DigitalOcean, Vercel, etc.).
    • Publish the updated WordPress site with the integrated chat widget.
  • Monitoring & Scaling:
    • Monitor usage, error logs, and API call volumes.
    • Scale resources (using serverless functions or auto-scaling containers) as needed.
