Now with username registration instead of email, and a new prompt improver feature I’m very stoked about!

Still 100% no code, all text prompts. Thanks for looking.

Cool idea. How did you think about the system prompt setup? Did you code it through Replit on use the console for the AI model you used?

Hey PMZ, thanks! The whole app was coded through Replit Agent and Assistant. I use ALL THE MODELS so this was my solution for flexibility across all, so it’s not fine tuned for any specific model currently. The improver feature uses Claude API.

I did have a pretty cool Chrome extension which was connected to Claude via API that would paste prompts in directly to the prompt field, but I broke it when adding user accounts and haven’t tried to fix it yet. Not sure if that answers your question, I apprecaite you asking and thanks.
