Description
Hey, I'm Nenad. I built Grafly (https://grafly.io) because I kept reaching for different tools just to sketch out a quick architecture diagram and hating either the UI, color schemes, usage patterns or that I had to log in, or have my doodles stored on someone's server. It's a React/React Flow app that runs entirely in the browser meaning that everything saves to localStorage, nothing leaves your machine. You get basic shapes, AWS/GCP icons, edges with waypoints and shareable URLs that encode the whole diagram in the query string (no backend, just LZ compression). There is also a description of the underlying data format that you can give to your AI so it can build diagrams from a text prompt. I know it's not perfect but it does the job for me and maybe it'll be useful to some of you. Code is on GitHub, AGPL licensed. https://github.com/lnenad/grafly

Same idea, different domain
Nobody's really built a content generation tool for Government yet.
