Marketing copy prompts for Claude Fable 5
Six scaffolds for launch copy, positioning and variants, written to get past the default marketing voice.
What actually helps here
Ban the vocabulary you do not want, by name. "Unlock", "seamless", "game-changing", "in today's fast-paced world" — listing the specific phrases works far better than asking for copy that is "not generic". Then give one competitor's page as an anti-example and say what you want to be different about yours.
The prompts
Fill in the bracketed slots, paste into any Claude app or the API. Written for Fable 5's goal-first style — they state the outcome and the constraints rather than scripting the steps.
Headline variants
Generate 5 headline variants for [product] aimed at [audience]. Vary the angle: outcome, pain point, curiosity, social proof, urgency. Max 9 words each.
Landing-page hero
Write a landing-page hero for [product]: headline (max 8 words), subheadline (max 20 words), and 3 benefit bullets. Tone: plain, confident, no hype words.
Onboarding email sequence
Draft a 3-email onboarding sequence for [product]: welcome, activation nudge, social proof. Subject lines plus 80-word bodies. One clear CTA per email.
Positioning statement
Write a positioning statement for [product]: for [audience] who [need], unlike [alternative], it [key difference]. Then translate it into one casual sentence.
Platform-specific posts
Turn this announcement into 3 platform-specific posts (X, LinkedIn, newsletter blurb): [paste announcement]. Match each platform's tone and length norms.
Objection handling
List the top 5 objections [audience] would have to [offer], and write a one-paragraph response to each that concedes what's true before countering.
Getting more out of these
Two habits matter more than the wording. Replace every bracketed slot before you send — Fable 5 follows instructions literally, and an unfilled [topic] becomes part of the task. And resist adding "think step by step" or "show your reasoning": on Fable 5 that phrasing can trip the reasoning_extraction classifier and hand your request to Opus 4.8 instead.
Need something these do not cover?
The generator builds a full system prompt around your own task, autonomy level and output style, and hands back the API call to go with it.
