I built a learning app where Claude reads your handwriting and drawings, then responds using your existing Claude subscription

I like learning by writing and drawing—mind maps, arrows, connections between ideas. A chat box feels limiting for that. I wanted Claude on the page I was writing on. So I built WonderEmber. You write a question on your iPad with Apple Pencil. Claude reads the whole page and responds in red handwriting beneath what you wrote, then asks you something back. I wanted it to make me think, so I’ve prompted it to ask follow-up questions and give hints before giving me the answer. I built it over months with Claude Code, one real learning session at a time. I'd study something (neural networks, statistics, how LLMs work), hit something that broke or annoyed me, and fix it next. I also like going on tangents when I learn. Claude follows wherever the page goes. WonderEmber runs on your Mac, where it connects to Claude Code using your own login. You write on your iPad with Apple Pencil. I already pay for a Claude plan, so I built it to use that subscription. No API key or separate API credits. It's free while it's in beta, but you need a paid Claude plan (Pro, Max, Team, or Enterprise). Happy to answer any questions. If you learn this way too, what would you want to try it with? I’m looking for a few early users and would love to see how other people use it. https://wonderember.com
