I love Excalidraw (https://excalidraw.com) - the virtual whiteboard. Its UX is great - simple and intuitive - and really makes it easy for me to express my thoughts and explain complex concepts with a quick sketch. I want to use it to make slides! However Excalidraw is not specifically designed for that. I used it for that many times actually, but the workflow is quite cumbersome: drawing a same-sized perimeter for each slide, adding to each slide watermarks and other common elements, exporting each slide as PNG into a powerpoint... it takes a long time! So well, here's Excalideck to simplify that workflow. 🙂 It's still in early development, so it's not very polished. But you're welcome to give it a try, make some slides, and let me know how it goes!
