Show HN: PlantDiagrams – AI-powered PlantUML editor Hi HN! I couldn’t find a truly user-friendly PlantUML editor, so I set out to build one. PlantDiagrams lets you describe a diagram in plain English; it generates the PlantUML and renders it instantly. The goal is to shorten the path from idea → diagram without fighting the editor. Tech: - Next.js / Supabase / FLy.io / Vercel Highlights - Natural-language to PlantUML with live preview - Export diagrams (SVG/PNG/TXT) - Organize work with Projects - Share via link; optional comments for review - Sample gallery to open and tweak examples Try it: https://bit.ly/4n5bBMy https://bit.ly/4n5bBMy September 19, 2025 at 09:34PM
