I ran an experiment:

Same 50 tasks. ChatGPT vs Claude vs Gemini. No hand-holding.

10 tasks required zero human intervention.

The results changed how I work forever.

Here's what actually works: 👇 Image
1/ Coding apps

Mega prompt you can use to turn any LLM into an expert programmer:

"
# ROLE
You are a senior software engineer with 15+ years of production experience across full-stack development, system design, and DevOps.

# TASK BREAKDOWN
For every coding request, structure your response as:
1. Architecture & Design Decisions - explain the approach and why
2. Implementation - write complete, production-ready code
3. Edge Cases - identify potential failures and handle them
4. Testing Strategy - unit tests and integration considerations
5. Deployment Notes - what to watch in production

# CODE QUALITY STANDARDS
- Include error handling and logging
- Add inline comments for complex logic
- Follow language-specific best practices
- Optimize for readability first, performance second
- Provide security considerations where relevant

# OUTPUT FORMAT
Present code in executable blocks. Explain tradeoffs between different approaches. If something will break at scale, tell me now.
"
2/ Research analysis

I fed Gemini a 40-page research paper on transformer architectures.
Asked it to: extract key findings, identify methodology gaps, and generate 5 follow-up research questions.

Got back a synthesis that would've taken me 6 hours. Took 90 seconds.

The prompt: "Analyze this paper as a PhD researcher. Extract: (1) core thesis, (2) methodology, (3) results with specific metrics, (4) limitations the authors didn't mention, (5) adjacent research directions worth exploring."
3/ Writing complete technical docs

Most people use AI for drafting. Wrong approach.

I use it for complete documentation from scratch.

The prompt: "You're writing API documentation for developers. Include: authentication flow, all endpoints with request/response examples, error codes, rate limits, and a quickstart guide. Write for someone who's never used our API."

Gemini crushed this with proper code blocks and realistic examples.
4/ Data analysis and visualization

Uploaded a messy CSV with 10k rows of sales data to ChatGPT.

"Clean this data, identify trends by region and product category, flag anomalies, and write Python code to generate 3 visualizations that tell the story."

It caught a data entry error I missed, found seasonal patterns, and delivered matplotlib code that worked first try.

Zero manual spreadsheet work.
5/ Email automation at scale

Not just "write me an email."

"Draft 5 variations of a cold outreach email to SaaS founders. Each should: open with a specific observation about their company, position our solution around their current growth stage, include social proof, end with a low-friction ask. Tone: knowledgeable peer, not salesperson."

Got back emails that actually sounded human. A/B tested them, 34% response rate.
6/ Meeting notes to action items

I paste raw Zoom transcripts into Claude.

The prompt: "Extract: (1) all decisions made with owner and deadline, (2) open questions that need answers, (3) action items by person, (4) topics that need follow-up meetings. Format as a structured doc I can send to the team immediately."

Saves me 30 minutes per meeting. The summaries are clearer than what I'd write manually.
7/ Content repurposing

Take one long-form piece, turn it into 10 different formats.

"Take this blog post and create: (1) Twitter thread with 8 tweets, (2) LinkedIn post, (3) 3 short TikTok scripts, (4) email newsletter version, (5) 5 pull quotes for graphics. Maintain core message, adapt tone for each platform."

ChatGPT handles this in one shot. What used to take 2 hours now takes 5 minutes.
8/ Code review and debugging

Paste broken code into Claude, add: "Review this code as a senior engineer doing a PR review. Identify: (1) bugs and why they'll cause issues, (2) performance bottlenecks, (3) security vulnerabilities, (4) readability improvements. Provide fixed version with explanations."

It caught a race condition I missed for 3 days. Suggested a caching layer that cut API calls by 60%.

Better than most human code reviews I've gotten.
9/ Building complete automation workflows

The wildest one.

"Design an n8n workflow that: monitors my Gmail for invoices, extracts data using OCR, updates a Google Sheet, sends Slack notifications for amounts over $1000, and files receipts in Drive. Provide the complete JSON and setup instructions."

Gemini gave me a working n8n template. Took 20 minutes to deploy, now saves me 4 hours per week.
10/ SEO content clusters

This one prints money.

"Generate a complete SEO content cluster for 'AI automation tools.' Include: (1) pillar page outline with H2s and H3s, (2) 10 supporting articles with target keywords, (3) internal linking strategy, (4) meta descriptions for each. Research intent: informational → comparison → decision."

Gemini researched competitors, identified content gaps, delivered a 3-month content roadmap.

What agencies charge $15k for, I got in 12 minutes.

Claude Pro just became the best $20/month I spend.

I use it for workflow automation, trend analysis, and document processing.

Here are 12 Claude prompts that replaced my $200/month research subscriptions: Image
Prompt 1: "Analyze these 5 competitor websites [paste URLs]. Extract their value props, pricing psychology, objection handling, and CTA strategies. Show me what's working and what gaps I can exploit."

This single prompt replaced my marketing consultant. Projects context means it remembers everything. Used this to 3x our conversion rate.Image
Prompt 2: "Read this 80-page market research PDF. Give me: (1) counterintuitive insights others will miss, (2) 3 immediate opportunities, (3) risks everyone's ignoring. Format as a strategic brief."

Turns dense reports into actionable intelligence in 90 seconds. The Artifacts feature makes it presentation-ready instantly.Image

I collected every Claude prompt that went viral on Reddit, X, and research communities.

These turned a "cool AI toy" into a research weapon that does 10 hours of work in 60 seconds.

13 copy-paste prompts. Zero fluff. Image
1. The “Contradictions Finder”

Perfect for papers, reports, or long docs.

“List all internal contradictions, unresolved tensions, or claims that don’t fully follow from the evidence.”

It catches things humans gloss over.
2. The “Reviewer #2” prompt

Yes, that reviewer.

“Critique this like a skeptical peer reviewer.
Be harsh. Focus on methodology flaws, missing controls, and overconfident claims.”

Brutal. Necessary.

RIP McKinsey.

You don’t need a $300k consultant anymore.

You can now run full competitive market analysis using ChatGPT, Gemini, and Grok deep research features.

Here are the exact 3 mega-prompts I use to replicate McKinsey-style insights for free: Image
Let me tell you what McKinsey consultants actually do:

1. Analyze industry trends and competitive dynamics
2. Benchmark companies and products
3. Identify strategic risks and opportunities
4. Package it all in fancy slides and charge 6 figures

But guess what?

AI can now do 90% of that instantly.

Let me show you how:
We use these 3 mega prompts for different tasks:

1/ The Consultant Framework

Prompt: "You are a world-class strategy consultant trained by McKinsey, BCG, and Bain. Act as if you were hired to provide a $300,000 strategic analysis for a client in the [INDUSTRY] sector.

Here is your mission:

1. Analyze the current state of the [INDUSTRY] market.
2. Identify key trends, emerging threats, and disruptive innovations.
3. Map out the top 3-5 competitors and benchmark their business models, strengths, weaknesses, pricing, distribution, and brand positioning.
4. Use frameworks like SWOT, Porter’s Five Forces, and strategic value chain analysis to assess risks and opportunities.
5. Provide a one-page strategic brief with actionable insights and recommendations for a hypothetical company entering or growing in this space.

Output everything in concise bullet points or tables. Make it structured and ready to paste into slides. Think like a McKinsey partner preparing for a C-suite meeting.

Industry: [INSERT INDUSTRY OR MARKET HERE]"

WARNING: After you use these prompts, you’ll never write the same way again.

This might be the most useful thing I’ve shared all year.

Here are 12 prompts turn any LLM into a full writing studio that works harder than you do: (Finance Guy edition)👇
1/ The “Voice Injection” Prompt

Gets the model to fully absorb your writing style.

“Here are 5 samples of my writing. Extract my tone, pacing, sentence structure, and emotional signatures. Confirm when my ‘voice profile’ is ready.”

This sets the foundation. Image
2/ The “Idea Engine” Prompt

Infinite hooks, titles, and angles.

“Generate 20 content ideas that could go viral in my niche. Mix curiosity, tension, and contrarian angles. No clichés.”

It’s like having a strategy intern. Image

Perplexity Pro just became the best $20/month I spend.

I use it for market research, trend analysis, and competitive intelligence.

Here are 12 prompts that replaced my $900/month research subscriptions: Image
Prompt 1: "Analyze the last 50 funding rounds in [industry]. Break down average valuation, revenue multiples, and which investors are most active. Compare to 6 months ago."

This single prompt replaced my PitchBook subscription. Gets real-time data with sources. I used this to time our Series A perfectly.Image
Prompt 2: "Find every company building [specific solution]. Show their revenue model, team size, last funding, and biggest customer wins. Flag which ones pivoted from something else."

Competitive intel that used to take 3 days now takes 4 minutes. The pivot history part is chef's kiss.Image

BREAKING: AI can now build you a business in 24 hours.

Here are 16 insane Grok 4 prompts to turn any idea into income in 2026: (Save for later) Image
1/ THE BUSINESS IDEA GENERATOR

"I have $500 and 10 hours per week. Analyze current market gaps, my skills in [your skills], and generate 5 business ideas I could launch this month. Include startup costs, timeline, and first revenue projections."

This prompt is stupid powerful.
2/ THE COMPETITOR DESTROYER

"Act as a market analyst. Research [competitor name] and identify 3 weaknesses in their offering. Then create a differentiation strategy I could execute with limited budget to capture their customers."

Watch them panic.
