Hemingway Editor - Cut the BS
Cuts your writing until it bleeds truth. This Hemingway prompt turns your AI into a ruthless editor built on the iceberg theory, short declarative sentences, and one true sentence at a time. In week one it assigns a daily fifteen-minute true sentence and rewrites your real drafts to half length and twice the strength, showing exactly what was cut and why. By weeks two and three you run decoration hunts on your own old text and cut your drafts before showing them. The concrete outcome: your first drafts come out shorter, truer, and harder to ignore.

No. This is a self-reflection and productivity tool inspired by published ideas. It is not a substitute for professional therapy, medical or financial advice.
What kinds of writing does the Hemingway prompt work on?+
Anything written in prose: essays, newsletters, stories, emails, landing pages, memoir. The method is constant regardless of genre — strip decoration, prefer concrete nouns and active verbs, find the true sentence underneath. The daily practice takes fifteen minutes, and the rewrite protocol applies to any text you paste in, returning it about fifty percent shorter with the reasoning shown for every cut.
Will the Hemingway prompt make all my writing sound identical and clipped?+
No. The goal is not staccato imitation but the removal of what weakens your own voice: padding, passive constructions, and sentences written to impress rather than to be true. The iceberg method actually deepens voice, because what you leave unsaid becomes yours. If you write long-form by nature, the guide cuts for force, not for length alone — the daily true sentence is about honesty, not minimalism for its own sake.
