Visually it looks pretty good. However like what jamisonbryant said, people on this website aren't fans of when they have to sign in to test something. I made a test account to try it out, and unfortunately submitting my prompt resulted in a Error status 504 on the request with message
"An error occurred with your deployment
FUNCTION_INVOCATION_TIMEOUT"
This is probably because you are waiting for the external openAI API's response before responding to the user's request. You might want to return a response immediately and asynchronously process the openAI part of things and notify the user when its ready somehow.
That being said, I caved and set up an account with a temp email and the password 'password' (might wanna check on those password security rules) just to play with it so I could give some constructive feedback. Unfortunately, generating a story isn't working (the spinner is spinning infinitely) and I see a few errors and warnings in the Developer Console. I'm not sure what the Short Stories page is supposed to show, either, but it also appears to be malfunctioning.
I don't mean to eviscerate your project - it is always exciting and scary to share something with the world. This needs a little more work before it's ready for show-and-tell, though, IMO. I'm not even sure what I would use this for. Best of luck.
Like jamisonbryant said, people want some assurance about what they’re getting in exchange for their personal info and a direct line to their email.
For UI, I might suggest something more “inlined” for the prompt screen. You might find some inspiration from outline writing apps like OmniOutliner [0] or emacs’ org-mode. Those will let you move around heading and groups of rows easily. If you could expand a row into multiple heading rows generated by AI, I could see that being really “in flow” for a writer!
You could imagine someone writing a couple details, hitting some key combo that expands it into a few headings, and then they can move around to the heading they want to expand on and start writing in it. They can recursively expand sentences/rows when ever they need to flesh something out.
It’s hard to get keycombos and the feel right, but I think it would be worth it.
