What it does when it runs
Rewrite sales copy in a plain, declarative, Hemingway register — short sentences, concrete words, no hedges. Use when the user asks for copy to be tighter, plainer, more direct, or "like Hemingway". Not for warm nurture content or long-form storytelling.

Hemingway Tonality
A final pass for emails, LinkedIn posts, proposals and call scripts. The goal is not to sound like a novelist. The goal is to be understood on the first read by someone with thirty seconds.
Rules
- Short sentences. Average under fifteen words. One idea per sentence. If a sentence has a comma and an "and", it is probably two sentences.
- Concrete nouns. "Pipeline" not "revenue motion". "Reps" not "sales resources". "Email" not "touchpoint".
- Strong verbs. Replace "is able to", "helps to", "serves to" with the verb itself. "Cuts ramp time" not "helps to reduce ramp time".
- No hedges. Delete "just", "really", "very", "quite", "actually", "I think", "I believe", "sort of", "kind of", "in order to".
- No stacked adjectives. One adjective if it carries information. Zero if it does not. "Innovative, seamless, powerful platform" becomes "platform".
- No abstractions where a number will do. "Faster" becomes "two days instead of nine". If there is no number, say what happens.
- Active voice. "We ship Tuesday" not "Shipping is scheduled for Tuesday".
- Cut the first sentence. It is usually a warm-up. Check whether the second sentence is the real start.
- End on the ask or the fact. Not on a pleasantry.
- Keep the meaning. This is a register change, not an edit of substance. Do not remove a claim, a number or a commitment. Flag anything you were tempted to cut for substance reasons.
Process
- Read the whole piece once.
- Rewrite top to bottom applying the rules.
- Read the rewrite aloud in your head. Anything you stumble on, split or cut.
- Return the rewrite, then a short list of what changed and why — three to five bullets, no more.
- If the original was under 60 words already, say so and change only what the rules demand.
Before / after
Before (71 words): I hope this email finds you well! I just wanted to reach out because I noticed that your team has been growing really quickly, and I think our innovative platform could potentially help you to streamline your onboarding process in order to get new reps productive faster. Would you be open to a quick 15-minute call sometime next week to explore whether there might be a fit?
After (34 words): You hired eleven reps in March. Most teams lose the first six weeks of a cohort to account research. We cut that to two for Loom and Ramp. Is ramp time a number you track?
What changed: cut the greeting and the "I noticed" frame; replaced "growing quickly" with the number; replaced "streamline onboarding" with what happens; replaced the meeting request with a one-word question.
