## What Did You Do Today? > This diary is written later and most of the details are lost. Today’s night I chatted with [[Echo]], a lady from Shang Hai saying that she is developing a new knowledge management tool like Obsidian and she want the graph to be 3D. <video src="https://res.cloudinary.com/yomaru/video/upload/v1701801089/obsidian/ri0rqtop03ypf19wgjbw.mp4" controls="controls" style="width: 100%;"></video> The full video is on one drive. I am happy to know her. She is a knowledge management expert and graphic artist. She organizes her notes using excalidraw in visualized way and I am impressed. I cannot imagine how much time she has spent in her vault. We exchange contact on Wechat and then I slept.
