What Is the Prompt Vault?
The Prompt Vault is a curated archive of original, craft-focused writing prompts designed to challenge youth writers and spark bold stories. It is a space for those who seek to push the boundaries of their imagination and explore the shadows of their own creativity.
Founder’s Choice
Founder’s Choice is a curated collection of writing prompts selected for their depth, originality, and storytelling potential.
But more than that—it comes from a place I know well.
As a writer myself, I understand what it feels like to sit in front of a blank page, wanting to create something meaningful but not knowing where to begin. That pause, that uncertainty—I’ve been there.
This space was built from that experience. Each prompt is chosen not just to inspire, but to challenge—to open up darker ideas, psychological layers, and imaginative worlds that push your writing further.
I’m Soubhagyaa S., founder of The Obsidian Review, and as both a writer and an author, I wanted to create something I once needed—a place to begin.
Take your time with these. Let one stay with you. Let it grow into something that’s entirely yours.
