"Tathya" is a Sanskrit word meaning "truth" or "fact," and "Seva" means "service." True to its name, Tathya Seva Playground provides a service dedicated to truth — offering tools for both fact-checking existing content and generating new, well-researched content. ![PlaygroundScreenshot.png](PlaygroundScreenshot.png)--DIVIDER--### Key Features - **Content Verification**: Upload any content to receive a detailed veracity score and analysis. - **Content Generation**: Specify a topic to generate comprehensive, factually accurate content. - **AI-Powered**: Utilizes OpenAI's latest GPT-4o model for superior results. - **Intelligent Agents**: Leverages CrewAI for orchestrating specialized AI agents. - **Clean UI**: Features a responsive, user-friendly interface for seamless interaction.--DIVIDER--## Technical Architecture Tathya Seva Playground is built with a modern stack that focuses on reliability, scalability, and developer experience. Let's break down its core components: ![TechnicalDiagram.png](TechnicalDiagram.png)--DIVIDER--### Backend Framework The application uses **Flask**, a lightweight Python web framework, providing a solid foundation for building RESTful APIs and serving web pages. ```python # app.py - Core application setup import os import logging from flask import Flask, request, jsonify, render_template from agents import ResearchCrew # Configure logging logging.basicConfig(level=logging.DEBUG) logger = logging.getLogger(__name__) app = Flask(__name__) app.secret_key = os.environ.get("SESSION_SECRET") # Initialize Research Crew crew = ResearchCrew() @app.route('/') def index(): return render_template('index.html') ```--DIVIDER--### AI Agent Orchestration At the heart of Tathya Seva is the **CrewAI** framework, which enables the creation and orchestration of specialized AI agents. Each agent has a specific role, goal, and capabilities, and they work together to deliver comprehensive results. ```python # agents.py - Agent orchestration from crewai import Agent, Task, Crew class ResearchCrew: def __init__(self): self.api_key = os.environ.get("OPENAI_API_KEY") if not self.api_key: raise ValueError("OpenAI API key not found in environment variables") def create_agent(self, role, goal, backstory): return Agent( role=role, goal=goal, backstory=backstory, allow_delegation=True, verbose=True, api_key=self.api_key, model="gpt-4o" # Using GPT-4o for all tasks ) ```--DIVIDER--### Fact Checking Process The fact-checking functionality involves receiving content, analyzing it through specialized agents, and returning a veracity score with detailed explanations. ```python # API endpoint for fact checking @app.route('/api/fact-check', methods=['POST']) def fact_check(): try: data = request.get_json() if not data or 'content' not in data: return jsonify({'error': 'No content provided'}), 400 content = data['content'] # Run fact checking process result = crew.run_fact_check(content) return jsonify({ 'veracity_score': result['score'], 'details': result['details'] }) except Exception as e: logger.error(f"Error in fact-check endpoint: {str(e)}") return jsonify({'error': str(e)}), 500 ``` Inside the `ResearchCrew` class, the fact-checking process is implemented as follows: ```python def run_fact_check(self, content: str) -> dict: """Run the fact checking process using a single agent approach.""" try: # Create a single fact-checking agent for simplicity fact_checker = self.create_agent( role='Fact Checker', goal='Verify the accuracy of information and provide a detailed assessment', backstory='Expert fact checker with extensive experience in information verification' ) # Create a single task for fact checking fact_check_task = Task( description=f""" Carefully fact-check the following content: {content} Format your response as a valid JSON object with this exact structure: {{ "score": number between 0 and 100, "details": "detailed explanation of the findings" }} STRICT REQUIREMENTS: 1. Response must be ONLY the JSON object 2. No text before or after the JSON 3. Use double quotes for strings 4. Properly escape special characters """, agent=fact_checker, expected_output="Valid JSON string containing score and details" ) # Execute the task and process the result # ... (result parsing code) ``` --DIVIDER--### Content Generation The content generation feature allows users to specify a topic and receive AI-generated content that is both engaging and factually accurate. ```python # API endpoint for content generation @app.route('/api/generate-content', methods=['POST']) def generate_content(): try: data = request.get_json() if not data or 'topic' not in data: return jsonify({'error': 'No topic provided'}), 400 topic = data['topic'] # Generate content result = crew.generate_content(topic) return jsonify({ 'content': result['content'], 'metadata': result['metadata'] }) except Exception as e: logger.error(f"Error in generate-content endpoint: {str(e)}") return jsonify({'error': str(e)}), 500 ```--DIVIDER--### Frontend Interface The application features a clean, responsive UI built with Bootstrap and custom CSS. Here's a snippet of the main interface: ```html Tathya Seva Playground - Content Management System

The necessary Python packages (listed in dependencies.txt) Set up your environment variables: ```bash # Required environment variables OPENAI_API_KEY='your-api-key-here' SESSION_SECRET='your-session-secret' # For Flask session management ``` ### Deployment on Replit Tathya Seva Playground can be easily deployed on Replit: 1. Fork the repository to your Replit workspace 2. Set the required environment secrets (OPENAI_API_KEY and SESSION_SECRET) 3. Click the Run button to start the application 4. Use the "Deploy" button to make your application publicly accessible--DIVIDER--## Handling Common Challenges During the development of Tathya Seva Playground, we encountered and resolved several challenges that are common in AI-powered applications: ### 1. Robust JSON Parsing One of the main challenges was handling the sometimes unpredictable output format from AI models. We implemented a robust JSON extraction system that can reliably parse responses: ```python # Extract JSON using a robust approach start_idx = result_str.find('{') end_idx = result_str.rfind('}') if start_idx == -1 or end_idx == -1: logger.error("No JSON object found in response") return {"error": "Could not extract JSON from response"} json_str = result_str[start_idx:end_idx + 1] parsed_result = json.loads(json_str) ``` ### 2. Detailed Logging Comprehensive logging is essential for debugging AI applications. We implemented detailed logging throughout the application: ```python # Super detailed logging logger.debug("=== Raw Fact Check Response ===") logger.debug(f"Response type: {type(result_str)}") logger.debug(f"Response length: {len(result_str)}") logger.debug(f"First 100 characters: {repr(result_str[:100])}") logger.debug(f"Last 100 characters: {repr(result_str[-100:])}") ``` ### 3. Clear Task Instructions When working with AI models, providing clear and structured instructions is crucial. We've found that explicit formatting requirements yield the best results: ```python description=f""" Write an engaging article about: {topic} Format your response as a valid JSON object with this exact structure: {{ "content": "your article content here" }} STRICT REQUIREMENTS: 1. Response must be ONLY the JSON object 2. No text before or after the JSON 3. Use double quotes for strings 4. Properly escape special characters """ ```--DIVIDER--## Future Enhancements Tathya Seva Playground has significant potential for expansion. Here are some planned enhancements: 1. **Caching Layer**: Implementing a caching mechanism to improve performance and reduce API costs 2. **Async Processing**: Adding asynchronous processing for handling large content verification requests 3. **Analytics Dashboard**: Creating a dashboard for monitoring agent performance and model selection metrics 4. **Multiple Model Support**: Expanding to support multiple AI models beyond OpenAI--DIVIDER--## Conclusion Tathya Seva Playground represents a powerful example of how AI can be harnessed to address real-world challenges in content verification and generation. By combining modern web technologies with advanced AI orchestration, it provides a robust platform that can be used by journalists, content creators, researchers, and anyone concerned with information accuracy.
