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.
Took a quick peek at your repo’s README, under features you have “Next.js”, cutting your teeth on some marketing is worth it! Think about what makes you want to use a tool, It’s probably not the framework it was built with.
The bent for this space tends to be towards start ups, so expect some advice towards how to market/best feature something you made, vs what would look best on a resume.
It should be possible to show the editor without the login-wall, but with the text input being disabled and be replaced by a pre-defined input like "Write me a story about bunny rabbits" (I don't know what your app is supposed to do so this is my understanding after reading the scant descriptions), and tell the user to hit "Generate story!" - but when they click it, the mock-up won't be talking to ChatGPT, instead it will just get a response (or one of several bunny rabbit stories) you've stored as text.
That way you don't need a login-wall, and no one will abuse the project and eat up your ChatGPT tokens (is that the reason for needing a login?).
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.
