The idea behind this website is amazing. Not only it has beautiful elements and easy to use UI, free plans, online presentation and many more features, it has a grid like story telling system. Let's say you have a business pitch with 10 slides, problem, solution, market size, ... These can be organized in linear way and you can add supporting material down the grid to answer questions etc. Also it has branding feature where you can save your Brand's color pallets and use it across teams.
