Hey Product Hunt 👋 I’m Alex, creator of Diagramahub. I built this because I was tired of switching between tools, losing diagram privacy, and struggling to iterate quickly with teams. Diagramahub is an AI-powered workspace where you can create, edit, and evolve diagrams using natural language — all in one place. ✨ What makes it different: - AI chat that actually understands and improves your diagrams - Support for Mermaid, PlantUML, and now D2 - Private rendering with self-hosted Kroki (no more public leaks) - Bring Your Own AI (use OpenAI, Anthropic, Gemini, etc.) - Built for developers, architects, and teams who think visually This is just the beginning — I’m actively building in public and would love your feedback. What would you like to see next? 🚀
