I've written 500 articles, 23 whitepapers, and 3 ebooks using Claude over 2 years, and these 10 prompts are the ONLY ones I actually use anymore because they handle 90% of professional writing better than any human editor I've worked with and cost me $0.02 per 1000 words: 👇
1. The 5-Minute First Draft
Prompt:
"Turn these rough notes into an article:
[paste your brain dump]
Target length: [800/1500/3000] words
Audience: [describe reader]
Goal: [inform/persuade/teach]
Keep my ideas and examples. Fix structure and flow."
2. Headline Machine (Steal This)
Prompt:
"Topic: [your topic]
Write 20 headlines using these formulas:
- How to [benefit] without [pain point]
- [Number] ways [audience] can [outcome]
- The [adjective] guide to [topic]
- Why [common belief] is wrong about [topic]
- [Do something] like [authority figure]
- I [did thing] and here's what happened
- What [success case] knows about [topic] that you don't
- automating marketing tasks
- building full websites and apps
- writing viral X threads, LinkedIn posts, and YouTube scripts
And it did all this in minutes.
Here are 10 prompts you can steal to unlock its full potential:
1. THE CAMPAIGN STRATEGIST
Opus 4.6's 200K context window means it remembers your entire brand voice across all campaigns.
Prompt:
"You are my senior marketing strategist with 10 years of experience in [your industry]. First, analyze my brand voice by reviewing these materials: [paste 3-5 previous posts, your about page, and any brand guidelines].
Then create a comprehensive 30-day content calendar that includes: daily post ideas with specific angles, optimal posting times based on my audience timezone [specify timezone], platform-specific adaptations (Twitter, LinkedIn, Instagram), CTAs tailored to each post's goal, and content themes organized by week.
For the top 5 highest-potential posts, create A/B test variations testing different: hooks, CTAs, content formats (thread vs single post vs carousel), and emotional angles. Include your reasoning for why each variation might outperform.
Finally, identify 3 content gaps my competitors are filling that I'm currently missing."
Opus maintains perfect consistency across 200K tokens. Other models lose your voice after 3-4 posts.
2. THE SPY MACHINE
Opus 4.6 processes competitor data 3x faster than GPT-4 and catches patterns humans miss.
Prompt:
"Act as a competitive intelligence analyst. I need you to reverse-engineer my competitors' entire marketing strategy.
Analyze these 10 competitor assets: [paste competitor landing pages, ad copy, email sequences, social posts, or URLs].
For each competitor, extract and document: 1. Core value proposition and positioning angle 2. Specific CTAs used and where they're placed 3. Social proof tactics (testimonials, logos, stats, case studies) 4. Pricing psychology (anchoring, tiering, urgency tactics) 5. Content strategy patterns (topics, frequency, formats) 6. Unique differentiators they emphasize
Then give me:
- 5 strategies they're ALL using that I'm missing (ranked by potential revenue impact)
- 3 positioning gaps in the market none of them are addressing
- 2 specific weaknesses in their approach I can exploit
- 1 bold contrarian strategy that goes against what everyone's doing
Present findings in a strategic brief format with implementation difficulty and expected timeline for each tactic."
Opus reads entire competitor websites in one shot. No "context too long" errors.
