    What's going on, the focus gets sucked away from the edit box after every keystroke?

    tried this:

       Generate Earth-like planet (10,000km diameter, 24h rotation, 23° axial tilt).
       Single supercontinent spanning 40% of surface area, centered on equator.
       Remaining 60% is ocean.
    
       Continent features:
         - Central desert plateau at 1,500m elevation, approximately 2,000km × 1,500km
         - Mountain range along entire eastern continental margin, peaks 4,000-6,000m
         - Gradual elevation decrease toward western coast
    
    Looks like it understood only „earth-like“ and 23° axial tilt, the map is fractal.

      Thanks for trying it out. I think I need to change the model that generates the preset. It’s currently using gpt-5-mini.

    I have tried a few things. Honestly this feels like some sort of very lazy vibe-coded app that superficially looks cool but does not actually produce anything of any value.

      Yep, it’s just a vibecoded project, and the model used for the preset isn’t great since I’m using gpt-5-mini. I’ll change the model. It’s just a fun weekend project only

    Thanks guys for the feedback. I’ve changed the preset generation model from GPT-5 Mini to GLM-5. The quality has improved a little, but the model is slightly slower

    As others have noted, the output doesn't seem to be anywhere close to what's being prompted.

      model I used for preset generation was gpt-5-mini. I’ve changed it to another model. Hopefully, it will follow the instructions better.

    Not working for me.

    Super cool idea, but I don't seem to be able to type in the text box. Tried Chrome and Firefox, same issue. Something taking focus from the text box as soon as I input anything?

    • error404x 2 days ago

      I’ll fix it. Sorry about the issue.
