“What Brimstone offers to do is add an entirely essential layer to the editorial and iterative process.”

“As writers we are always needing ways to springboard our ideas when faced with a blank page. Generative and iterative systems can help greatly with this, but as professionals the most important part of writing is building narrative framework and mechanics that adhere to scalable storytelling and worldbuilding. It’s this type of scaffolding where LLMs are more jackhammers than scalpels and ultimately create more work than improve productivity and most importantly, creativity. What Brimstone offers to do is add an entirely essential layer to the editorial and iterative process that is needed after the brainstorming and rough assemblies are done in the drafting process.”
