As a result, practitioners spend a great deal of time preparing and organizing data rather than analyzing it. This course is designed to use generative AI to reduce these repetitive tasks and enable participants to apply data analysis results to real-world decision-making. Market Trends Data analysis using generative AI is expanding from coding-centered analysis to file-based analysis driven by natural language questions. This course covers methods for exploring, analyzing, visualizing, and documenting data using ChatGPT, Excel Copilot, and Claude—without requiring coding skills or knowledge of complex functions. Expected Benefits Reduce the time required for data preprocessing and cleansing. Reduce repetitive formula, pivot table, and chart creation tasks. Enhance natural language-based data analysis skills.

Planning Background Generative AI is advancing beyond simple question-and-answer interactions to performing tasks such as document creation, data analysis, information retrieval, and workflow automation. However, in actual workplace settings, people still repeatedly explain the background and purpose to AI each time or start writing documents from scratch on a blank screen. To address these issues, this course is structured to provide step-by-step learning, from prompt design to building a work environment using projects, instructions, knowledge, and GPTs. Market Overview The generative AI market is expanding rapidly, and the course covers the size of the AI market in 2026, competition among major providers, and growth cases involving ChatGPT, Gemini, and Claude. The lectures present the 2026 AI market size as approximately $539.5 billion and explain that, alongside the spread of multimodal and agentic AI, cost, integration, and execution capabilities are becoming competitive factors in addition to performance. Use Claude, ChatGPT, and Microsoft 365 Copilot to streamline workplace reporting, proposal, and planning tasks.

How long are you going to manually look through 2,500 stocks every day? Searching through Naver Finance to find surging stocks after the market closes, Reading news to judge whether it's good or bad news, Checking foreign/institutional supply and demand one by one, Opening charts to analyze patterns... Aren't you repeating this every single day? I used to do that too. I spent 2 to 3 hours after work analyzing stocks, and yet I still missed more stocks than I found. With over 2,500 stocks across KOSPI and KOSDAQ combined, it's impossible for a human to see them all every day. --- So, I built a system. I created a system that automatically analyzes 2,500 stocks every day after the market closes. - Automatically collects market prices, supply/demand, and news - AI (Gemini) reads the news and determines if it's positive or negative - Scores stocks out of 15 points based on 6 factors - Selects only the stocks that pass the criteria and calculates entry, stop-loss, and take-profit prices - Sends notifications via Telegram Now, I just check my phone after work. Additionally, every Saturday, the system analyzes its own performance from the past week and automatically adjusts stop-loss lines, take-profit lines, and holding periods. It is a structure where the system learns and improves on its own. --- But I am not a developer. I didn't write the code for this system myself. I gave all the instructions to the AI verbally. "Filter out stocks that rose more than 5% today with a trading volume exceeding 50 billion won." "Send these 3 news articles to Gemini and have it judge if they are positive." "Create a scheduler so this runs automatically every day at 4 PM." When I speak like this, the AI (Claude) generates the code. This is "Vibe Coding." --- In this course, we will build this exact system. Over 58 lessons, we will build the system I actually use every day from start to finish. Starting from data collection, AI news analysis, scoring engine, signal generation, Flask API server, Next.js web dashboard, Telegram automatic notifications, and even the self-learning system. The final product is not a Jupyter Notebook. The final product is a web dashboard and Telegram notifications that actually run every day. You don't need to know how to code. In every lesson, I will show you how to talk to Claude, and if you follow along, you will get the same results. --- Recommended for: - Office worker investors who lack the time to analyze stocks every day - Those who want an automated system but don't know how to code - Those curious about quant/system trading but don't know where to start - Those curious about how to utilize AI in practice --- ⚠️ This course does not guarantee investment returns. This is a programming course on building your own stock analysis tools. Actual investment decisions are the responsibility of the student.
