Article Outline Builder
Blog Claude / ChatGPT Beginner
Create a detailed outline for a blog post on [TOPIC]. Target keyword: [KEYWORD] Word count target: [1000 / 1500 / 2500] Audience: [DESCRIBE] For each section include: - H2 heading (keyword-conscious but natural) - 2-sentence description of what the section covers - The key point or takeaway the reader gets - Any data, example, or statistic to include Flag which sections will drive the most SEO value and why.
Use this first, then approve the outline before generating the full article. Faster iteration than fixing a bad 1,500-word draft.
Listicle Post Generator
Blog Claude / ChatGPT Beginner
Write a listicle blog post: "[NUMBER] Best [THINGS] for [AUDIENCE] in [YEAR]" For each item include: - Bold item name - 2-3 sentence description of what it is and why it's on the list - One specific, concrete detail (a stat, a price, a use case, a weakness) - Who it's best for (one sentence) Opening paragraph: explain why this list exists and what makes something qualify. No generic "in today's fast-paced world" openings. Closing paragraph: how to choose from the list (1 decision framework).
Works for: "7 Best AI Tools for Writers", "10 Best Running Shoes for Beginners", "5 Best Credit Cards for Travel". Adapt the [THINGS] to your niche.
Personal Story → Blog Post
Blog Claude Intermediate
Turn this personal story into a blog post that other [AUDIENCE] will find useful. Story: [DESCRIBE THE EXPERIENCE IN YOUR OWN WORDS — ROUGH NOTES ARE FINE] Structure: 1. Open with the most interesting moment from the story (not the beginning) 2. Flash back to context: what was happening, what the challenge was 3. What I tried that didn't work 4. What I discovered or changed 5. The result (specific, honest) 6. What this means for the reader — what they can take and apply Write in first person. Keep my voice casual and direct. Under 1,000 words.
Best with: Claude — better at preserving personal voice. Give rough notes, not polished prose. Claude will find the structure in your raw story.
Comparison Post Framework
Blog Claude / ChatGPT Intermediate
Write a comparison blog post: "[OPTION A] vs [OPTION B]: Which Is Right For You?" Opening: one paragraph giving a genuine verdict upfront (not a hedge — pick a winner for the majority of readers) Comparison sections (one H2 per dimension): - [Dimension 1: e.g., price, ease of use, quality, etc.] - [Dimension 2] - [Dimension 3] - [Dimension 4] For each dimension: explain what each option offers, which wins and why. "Who should choose [A]" section: 3 bullet points of specific user types "Who should choose [B]" section: 3 bullet points of specific user types Closing: restate the verdict, add one caveat, link to related content.
High SEO value: "[X] vs [Y]" searches have very high purchase intent. Fill in real dimensions relevant to your products.

Newsletter Prompts

Prompts for weekly newsletters, drip sequences, and one-time broadcasts. Claude is the best tool for newsletter writing — it produces more natural prose and matches voice instructions precisely.

Weekly Newsletter Issue Generator
Newsletter Claude Intermediate
Write this week's newsletter issue. Here are my notes: Topic: [MAIN TOPIC] My angle/opinion: [WHAT I THINK ABOUT IT] Key insight I want to share: [THE ONE THING READERS SHOULD WALK AWAY WITH] Any data or examples to include: [OPTIONAL] Newsletter details: Audience: [WHO READS THIS] Tone: [casual / professional / witty] Typical length: [400-600 words] I end every issue with: [YOUR STANDARD SIGN-OFF OR CTA] My voice: [paste 2-3 sentences from past issues you liked, OR describe: "direct, no filler, short sentences, occasional humor"]
Key: The "My voice" field is the most important. Past examples beat any description. Paste 100-200 words from previous issues you liked and Claude will match the cadence.

Welcome Email Sequence (5-part)
Newsletter Claude / ChatGPT Intermediate
Write a 5-email welcome sequence for new subscribers to [NEWSLETTER NAME]. Newsletter description: [WHAT IT COVERS, WHO IT'S FOR] Product or service I eventually want to pitch: [OPTIONAL] Email 1 (Day 0 — immediate): Welcome + one surprising thing about me/the newsletter Email 2 (Day 2): My best content from the archive (3 links with one sentence on each) Email 3 (Day 4): The story of why I started this newsletter (personal, specific) Email 4 (Day 7): A framework or tool I use that my audience would find genuinely useful Email 5 (Day 10): Ask what they struggle with most + soft CTA to [PRODUCT/SERVICE] Each email: 200-300 words. Subject line + preview text for each. Conversational tone.
Use case: Set up in MailerLite, ConvertKit, or Beehiiv automations triggered by new subscriber. Most newsletters send one welcome email — a 5-part sequence builds the relationship 5x faster.
Subject Line Generator (A/B test set)
Newsletter Claude / ChatGPT Beginner
Write 10 subject line options for a newsletter email about [TOPIC]. The email is about: [ONE SENTENCE SUMMARY] Main benefit to the reader: [WHAT THEY GET FROM READING IT] Audience: [WHO THEY ARE] Write 2 of each type: - Curiosity gap ("The one thing most people miss about...") - Direct benefit ("How to X in Y minutes") - Numbered list ("5 things I learned about...") - Contrarian ("Why you should stop [common advice]") - Question ("Are you making this [X] mistake?") Also write preview text (45 chars) for each subject line.
A/B test: Pick the 2 most different options and split your list. The difference between a 20% and 40% open rate is often just the subject line.

Social Media Prompts

Platform-specific prompts for LinkedIn, Instagram, X/Twitter, and TikTok. The best social content sounds like a person, not a press release — these prompts enforce that.

LinkedIn Thought Leadership Post
Social Claude Beginner
Write a LinkedIn post about [TOPIC OR OBSERVATION]. My take on it: [YOUR OPINION OR ANGLE] Relevant experience or example: [OPTIONAL STORY OR FACT] Requirements: - First line must be 8 words or fewer and create curiosity or state a bold claim - No emojis in the first line - No bullet lists in the first 3 lines - 200-250 words total - End with one question that invites genuine comment - Do NOT start with "I" or "As a [title]" - Do NOT use: "thrilled to announce", "I'm humbled", "excited to share", "game-changer"
The first line determines everything on LinkedIn — it's all people see before "see more." Test multiple first lines if the initial output feels flat.
Instagram Caption with Hashtags
Social Claude / ChatGPT Beginner
Write an Instagram caption for [DESCRIBE THE POST/IMAGE]. Topic: [WHAT THE POST IS ABOUT] Tone: [educational / personal / funny / inspirational] Account niche: [YOUR NICHE] CTA: [what you want people to do: comment, save, visit link in bio, etc.] Caption requirements: - Hook line: bold, 10 words or fewer - Body: 3-5 sentences, conversational, sounds like a real person texting - CTA: natural, not desperate - 10-15 hashtags at the end (mix of large, medium, and niche) - Line breaks every 1-2 sentences (Instagram formatting)
Format matters: Instagram shows only 2-3 lines before "more". The hook has to earn the tap. Specify your account size in the prompt for better hashtag suggestions.
Thread / X (Twitter) Thread
Social Claude / ChatGPT Beginner
Write a Twitter/X thread about [TOPIC]. Main insight or argument: [YOUR POINT] Number of tweets: [8-12] Thread structure: Tweet 1: Bold hook — one surprising claim or counterintuitive statement (under 240 chars) Tweets 2-10: One point per tweet. Each standalone. Short sentences. No filler. Final tweet: Summary + CTA (follow / link / ask a question) Rules: - Each tweet under 240 characters - No hashtags except last tweet (1-2 max) - No "thread 🧵" formatting — just the content - Avoid: "here's what I learned", "let me break this down", "buckle up"
Threads that perform: each tweet should be shareable as a standalone tweet. If a tweet requires context from the previous one to make sense, it's too dependent — strengthen it.

Email Sequence Prompts

Prompts for cold outreach, nurture sequences, re-engagement, and transactional emails.

Cold Outreach Email (non-spammy)
Email Claude Intermediate
Write a cold outreach email to [RECIPIENT TYPE] from [MY ROLE]. What I'm offering: [ONE SENTENCE — BE SPECIFIC] Why this specific person: [WHAT I KNOW ABOUT THEM OR THEIR SITUATION] The outcome I'm promising: [SPECIFIC RESULT, NOT "help you grow"] My ask: [small ask — 15-minute call / reply / specific question] Requirements: - Subject line: 6 words or fewer, no clickbait - Opening: reference something specific about THEM (not "I came across your profile") - Under 120 words total - One clear ask at the end, no multiple CTAs - Do NOT say: "I hope this email finds you well", "I wanted to reach out", "synergy", "leverage", "circle back"
The best cold emails are shorter than you think necessary. 80 words beats 200 words. Cut everything that isn't: who you are, why them, what you want.
Re-engagement Email (win back inactive subscribers)
Email Claude / ChatGPT Beginner
Write a re-engagement email to subscribers who haven't opened in 90 days. Newsletter/brand: [NAME AND WHAT IT COVERS] Reason to come back: [NEW CONTENT / DIRECTION CHANGE / SPECIAL OFFER] Tone: [honest / self-deprecating / direct] Structure: - Subject line: honest, not salesy ("Haven't heard from us in a while") - Opening: acknowledge the silence directly — don't pretend it didn't happen - Body: one clear reason to re-engage (value, not guilt) - CTA: one button or link - Unsubscribe note at the end that's human ("No hard feelings if you want off the list")
Re-engagement rate: honest emails ("we've been quiet") get higher open rates than typical "we miss you" emails. The surprise factor works in your favor.

Sales Copy Prompts

Landing pages, product descriptions, and ad copy. Use Claude for long-form copy; ChatGPT is slightly better for punchy ad copy variations.

Landing Page Copy (full page)
Sales Claude Advanced
Write landing page copy for [PRODUCT/SERVICE]. Product: [NAME AND ONE-SENTENCE DESCRIPTION] Target customer: [WHO THEY ARE, THEIR SPECIFIC PROBLEM] Price: [PRICE POINT] Main benefit: [THE #1 OUTCOME THE CUSTOMER GETS] Secondary benefits: [2-3 MORE] Objections to overcome: [WHAT HOLDS PEOPLE BACK FROM BUYING] Social proof available: [TESTIMONIALS / REVIEWS / NUMBERS] Offer: [WHAT'S INCLUDED] Write in sections: 1. Hero: headline + subheadline + CTA button text 2. Problem section: 3-4 sentences naming the pain 3. Solution intro: transition to the product 4. Benefits (not features): 4-6 benefit statements 5. Social proof placeholder: format for [X] testimonials 6. Offer breakdown: what's included 7. Objection handler: address top 2-3 objections 8. Final CTA with urgency or scarcity if relevant
Fill in real objections: the objection section is where most AI-generated copy fails. Be specific: not "too expensive" but "they think $X/month is too much when they're already paying for [competitor]."
Amazon Product Description
Sales Claude / ChatGPT Beginner
Write an Amazon product listing for [PRODUCT]. Product details: [SPECS, MATERIALS, SIZE, WHAT IT DOES] Main keyword: [PRIMARY SEARCH TERM] Secondary keywords: [2-3 MORE] Key benefit: [WHAT PROBLEM IT SOLVES] Customer type: [WHO BUYS IT] Write: 1. Title (200 chars, front-load main keyword, include key specs) 2. Bullet points (5 bullets, start each with a capitalized benefit phrase) 3. Product description (150-200 words, tells a story, ends with CTA to buy) Avoid: passive voice, "great quality", "perfect for", "you won't be disappointed"
Amazon-specific: the title and first 2 bullets are the most important — that's all most shoppers read on mobile before deciding. Front-load the strongest benefit.

Editing & Rewriting Prompts

The most universally useful prompts in the vault. These work on any existing content — your draft, a client's copy, an old blog post, anything.

The Expert Rewriter (make it sharper)
Editing Claude Beginner
Rewrite the following text. Make it clearer, more direct, and more engaging. Keep every fact and all of the original meaning. Cut anything redundant. Aim for 20-30% shorter. Use active voice. Short sentences. No jargon. Text to rewrite: [PASTE YOUR TEXT HERE]
Most useful prompt in the vault. Works on emails, blog posts, product descriptions, anything. The 20-30% shorter target is key — forces cuts without losing meaning.
De-AI a piece of writing
Editing Claude Intermediate
Rewrite the following text to sound like it was written by a thoughtful human, not generated by AI. Specifically: - Remove all hedging language ("it's worth noting", "it's important to", "it's crucial to") - Replace "utilize" with "use", "leverage" with practical alternatives - Cut all filler transitions ("in today's world", "in conclusion", "without further ado") - Vary sentence length — mix short punchy sentences with longer ones - Add one specific, concrete detail where something is abstract - Remove all bullet lists unless truly necessary — convert to prose Keep the core meaning and all facts intact. Text: [PASTE AI-GENERATED TEXT HERE]
The tell-tale signs: AI writing uses "delve", "it's worth noting", "in conclusion" at much higher rates than human writing. This prompt systematically removes them.
Voice Matcher — write like me
Editing Claude Advanced
Analyze the writing style in the examples below, then write new content matching that style exactly. Writing examples: [PASTE 3-5 PARAGRAPHS FROM YOUR EXISTING CONTENT] Style notes (add anything the examples don't show): [e.g., "I use em-dashes a lot", "I avoid semicolons", "I use lowercase for impact sometimes"] Now write: [YOUR NEW PIECE — DESCRIBE TOPIC AND LENGTH]
Claude excels at this. The more examples you give, the better the match. For long-form work, give examples from the same content format (don't train on tweets if you want it to write blog posts).
