Show HN: I made a tool to convert recipes to an easy reading graphical notation https://ift.tt/OZzh9Pr

Show HN: I made a tool to convert recipes to an easy reading graphical notation Hi HN, I have been working on a project which can automatically convert a recipe to the tree/graph/tabular style notation that pops up on HN every now and then. It's still early days but I am keen to hear about improvements I can make to the recipe presentation. For reference, the earliest example I have seen of this style of notation is from 'Cooking For Engineers' ( https://ift.tt/7tuHUQe ) but I have seen other, similar notations from time to time. This is my take on the notation, as well as the ability to convert recipes automatically. In the future, I would like to see it become my own personal kitchen/recipe management system but I would first like to improve the recipe display options. It uses ChatGPT to format the recipe into a JSON tree structure, which is then rendered with CSS grid. So far it works well enough but there is definitely some recipes that are impossible to render, and of course ChatGPT will occasionally spit out less-than-useful trees. I have been using AppWrite for the backend. Curious to hear everyone's thoughts and what people might like to see! https://gobsmacked.io June 27, 2025 at 11:10PM
