Shakespeare doesn't build native apps - I would have used it if it did.
I used
@PayPerQ with Claude Sonnet 4.5 in my browser, copying the code into VS Codium on my computer, doing research to choose my approach and asking questions along the way. It gets expensive, but works well. I like the big context window, the memory for seeing the whole project at once. Anthropic closed my account and doesn't have anonymous payments.
I did a little bit with Maple AI too - hopefully it becomes easier to use for this with more file-sharing flexibility.
