Hey Fazier! 👋 I'm the maker of CodePic. I built it because every time I wanted to sketch a quick flowchart or system diagram, I'd either fight with heavyweight tools like Lucidchart / Miro, or open Excalidraw and miss having ready-made templates and AI generation. So CodePic is basically: an infinite whiteboard with Excalidraw-style hand-drawn rendering, but with 80+ templates baked in and an MCP server so you can ask Cursor / Claude to draw diagrams for you and then tweak them visually. A few things I care about: • Free with no watermark — the core canvas should just be free • No signup required to view a shared link • Fast — everything renders in Canvas 2D, no heavy framework on the canvas layer • AI is a helper, not the product — the whiteboard is the product Would love your feedback, especially on: 1. What templates are missing that you'd actually use? 2. How's the hand-drawn style on your screen — too rough / too clean? 3. Anything confusing in the first 60 seconds? Try it here: https://codepic.cc Templates gallery: https://codepic.cc/templates Thanks for checking it out 🙏
