📖 Overview

DataOS is a demonstration application showcasing the integration of Large Language Models (LLMs) with decentralized content storage. The application fetches content from Arweave and processes it through various LLM-powered pipelines to generate structured summaries, analyses, and debates.

This project was developed by Roark Technology as a proof-of-concept for intelligent content processing using decentralized infrastructure.

Key Features

• 🔗 Decentralized Content — Fetches articles directly from the Arweave permanent storage network
• 🤖 LLM Processing — Multiple analysis modes powered by OpenAI's GPT models
• 📊 Financial Analyst Mode — Extracts key facts and figures into structured tables
• 💬 Debate Mode — Generates pro/con analysis of article topics
• 🔊 Text-to-Speech — Optional audio synthesis via ElevenLabs integration
• 🎨 Modern UI — Responsive Twitter-inspired interface built with React and TailwindCSS

📜 Usage Guide

Analysis Modes

1. Financial Analyst — Extracts quantitative data, facts, and figures from articles into structured HTML tables
2. Debater — Generates balanced pro/con arguments for the article's main topic

Workflow

1. Launch the application
2. Select your preferred persona (Analyst, Debater, etc.)
3. Choose content category (Crypto, Entrepreneurship, etc.)
4. Click "GO" to start processing
5. View LLM-generated summaries in the feed
6. Use suggestion buttons to refine output
7. Toggle audio playback for text-to-speech (requires ElevenLabs)

⚠️ Known Limitations

• API Costs — Each processing run makes multiple API calls to OpenAI
• Rate Limits — High usage may hit OpenAI rate limits
• Outdated Dependencies — LangChain and other packages may have breaking changes in newer versions
• No Authentication — Demo app has no user authentication
• Arweave Content — Demo content IDs may become unavailable
