As the stock investment boom continues, real-time stock quote sites disguised as work Excel or email screens are becoming a hot topic among office workers.

On the 29th, stock sites styled to look like work programs have been shared one after another on online communities and social media. On the surface they look like ordinary spreadsheets or company inboxes, but in fact they are structured to let users check real-time prices for domestic and overseas stock markets and virtual assets.

One site displays KOSPI and KOSDAQ listings, the U.S. stock market, Bitcoin prices, and market news inside a screen that looks like an Excel document. The figures update in real time inside the cells.

Beyond simple quote lookup, it also offers real-time chat between users. People can freely share opinions on specific stocks and market trends.

What has especially drawn attention among users is the "Outlook version." On a screen similar to a company inbox, sender names that evoke actual corporate org charts appear, such as "Lee Jae-yong (Electronics Business Division)," "Choi Ji-peu, Vice Administrator (High-NIC Team)," and "Jeong Ja-dong, Director General (Vehicle Strategy Office)," and when you click an email, it takes you to real-time stock screens for Samsung Electronics, SK hynix, and Hyundai Motor.

Online, reactions included, "It really looks like a company work screen," "Give the developer an award," and "Now I can check stocks without worrying about being watched."
