I actually wrote an issue on the PromptPal GH around 30 minutes before my HN post. They use Metamask / Ethereum addresses for auth / account management, which sounds crazy to me for a product that's completely divorced from web3 / cryptocurrency.

Promptfolder isn't what I'm looking for unfortunately based on the template variable assignment the example has. I really just want to store text and get it back via an API. The text just happens to be a prompt.
