Design Quill
I made my own quill on Grok Bot, and it works really great so I thought I would share it. It gives feedback on graphic design, branding, and fashion choices (for in-person or on camera needs - that might just be me but it’s there). It should also give feedback on covers, but I haven’t tried that yet.
It gave accurate feedback and good options for fixing problems. I was using it for formatting my picture book, and the outcome does look significantly more polished and professional after implementing the advice.
