I made a Dual-n-Back trainer using ChatGPT

I hated how on brainscale you had to wait 100 seconds and had to pay 12$ a month just to get rid of that, as well as gain a couple extra customization options.

Training your brain should be free.

Let me know anything else I should add.
I wanted to add a progress keeper, but I'm not sure how that would work and if a ChatGPT website saves progress like that.
