Just Prompts is a small, free tool for building and saving better AI prompts using Additive Prompting – a prompt-structuring framework that adds context and nuance in layers to improve the accuracy and coherence of AI-generated output, developed and publicly documented by prompt engineer Nick St. Pierre.
Additive Prompting isn’t a vague marketing claim – it’s a specific, testable methodology with public documentation of real results, including a case demonstrated for interior design and architecture photography reaching 90%-plus coherence to the original prompt in Midjourney across repeated tests. The tool packages that technique with simple prompt-saving functionality, letting users apply the same structured approach repeatedly rather than reconstructing it from scratch each time.
Just Prompts targets individuals working with AI image and text generation tools who want more consistent, controllable output. It’s a small, free, independently-built tool – no pricing is published, and none appears to apply.
