Show HN: I made a spaced repetition tool to master coding problems

The linked article is about the Lanki.xyz website, which provides a platform for creating and sharing interactive web experiences. The article highlights the key features of the platform, including the ability to build interactive web experiments, visualizations, and simulations without coding. It emphasizes the user-friendly interface and the availability of pre-built templates and examples to help users get started. The article also mentions the potential applications of the platform in areas such as education, research, and creative expression.
