This is far easier to use than Lovable to begin with, it also backs up to Github or Gitlab, so there is choice. You can import code too. Most important, you can download your code at any time from Shakespeare with a zip file; this can't be done in Lovable unless you pay for the $50/mo sub, and it's impossible to find anyway. I can use any AI in Shakespeare, including Maple AI for privacy. I'm not sure what model Lovable uses or how to change it as someone who's not a coder or software developer. I feel like I have more control and choice in Shakespeare.
