Let’s Talk: Interactive AI Chat for Technical Blogs 🐨

Have you ever wished you could ask follow-up questions while reading technical content? Meet Let’s Talk – an AI-driven chat component designed to make technical blog content more interactive and accessible.

---

The Problem: Content Navigation Challenges

Technical blogs often present challenges for readers:

• Difficulty finding specific information across multiple posts
• Limited ability to explore topics in depth
• One-way communication without follow-up capabilities
• Reduced information retention

What Can You Do With Let’s Talk?

• Ask questions about blog topics – Get concise answers about RAG systems, LLMs, and more
• Request code examples – Receive practical code snippets for your use case
• Explore concepts deeper – Get clarification without searching multiple articles
• Receive personalized guidance – Information tailored to your background

Under the Hood: Technical Implementation

Let’s Talk combines several AI technologies:

• Document Ingestion: Supports ingesting documents from both the file system and websites
• Advanced Text Processing: Utilizes recursive text splitting and semantic chunking for optimal context management
• Retrievers: Includes BM25, multiple query retrievers, and semantic search for flexible information retrieval
• Advanced Embedding Technology: Leverages powerful models like Snowflake/snowflake-arctic-embed-l-v2.0 with flexible support for custom embedding models from any provider
• Vector Database: Qdrant for efficient content indexing
• Language Models: GPT-4o-mini for production, with GPT-4.1 for evaluation, plus support for integrating other LLMs and providers
• Orchestration: LangChain and LangGraph for the complete RAG workflow
• Interface: Custom Svelte component integrated with the blog's design

Try It For Yourself!

Let's Talk is available in multiple implementations:

• Live on TheDataGuy.PRO - Our initial implementation
• D365 Stuff Chat - Powering the D365 Stuff Blog
• Hugging Face Spaces - Try the prototype directly

Ask questions about RAG evaluation, research agents, data strategy, or any other topics from my blog to see Let's Talk in action!

Pipeline Scheduling and Management 🕐

Let's Talk now includes a comprehensive pipeline scheduling system built with FastAPI:

• Automated Content Updates: Schedule regular pipeline runs to keep your content up-to-date
• Flexible Scheduling: Support for cron expressions, intervals, and one-time runs
• REST API Management: Full API for creating, monitoring, and managing scheduled jobs
• Real-time Monitoring: Health checks, execution statistics, and error tracking
• Preset Configurations: Common scheduling patterns (daily, weekly, hourly)

Quick Start with Pipeline Scheduling

# Start the FastAPI scheduler server
./start_scheduler_api.sh

# Or manually with uvicorn
cd py-src && uv run uvicorn lets_talk.api.main:app --host 0.0.0.0 --port 8000

# Alternative: Use the main entry point
cd py-src && uv run python lets_talk/main.py

Visit http://localhost:8000/docs for the interactive API documentation.

For complete documentation, see Pipeline Scheduling API Guide.

Architecture Overview 🏗️

Let's Talk features a modular, layered architecture for maintainability and scalability:

Core Components

• agents/ - AI agent implementations (RAG, ReAct) with factory pattern
• api/ - FastAPI application with modular endpoints and Pydantic models
• core/ - Business logic (pipeline, scheduler, RAG retrieval, domain models)
• tools/ - External integrations and utilities (RSS, datetime, contact forms)
• utils/ - Helper functions (blog processing, document formatting)
• shared/ - Configuration, constants, exceptions, and prompt templates

Getting Started

# Install dependencies
uv install

# Set up database (auto-migrates on startup by default)
export DATABASE_URL="sqlite:///./output/lets_talk.db"

# Run the API server
cd py-src && uv run python lets_talk/main.py

# Run pipeline manually
cd py-src && uv run python -m lets_talk.core.pipeline.engine

# Use scheduler CLI
cd py-src && uv run python -m lets_talk.core.scheduler.cli --help

# Manage database migrations manually (if needed)
./migrate.sh status
./migrate.sh upgrade

For detailed setup and configuration, see the documentation.

Import Examples

# Create agents
from lets_talk.agents import create_rag_agent, create_react_agent

# Access API
from lets_talk.api.main import app

# Use core components
from lets_talk.core.pipeline.engine import run_pipeline
from lets_talk.core.scheduler.manager import PipelineScheduler
from lets_talk.shared.config import Configuration

Future Enhancements
