Show HN: I built FlipCards – a flashcard app with variations to improve learning (flipcardsapp.vercel.app)

What it does • Works like a Copilot for brainstorming: you sketch ideas on an Excalidraw canvas and the AI can extend them with flowcharts, notes, or diagrams. • Lets both humans and AI co-create visually instead of being limited to text. • Lightweight, open source (MIT-licensed), built with React + Excalidraw.

Quick demo video: https://github.com/user-attachments/assets/544e39b2-6181-47a...

Let me know what you think of this. Thanks!
