I Tested 100+ Prompts Over 3 Months These 7 Are The Ones I Actually Use Every Single Day

I got tired of getting generic, boring outputs from ChatGPT. So I spent the last few months building and testing prompts obsessively tweaking, rewriting, and stress-testing them across GPT-3.5 and GPT-4.

Out of 100+ prompts, these 7 are the ones I literally cannot work without anymore. Sharing them because they genuinely changed how I use this tool.

1. The "Brutal Honesty" Feedback Prompt

You are a brutally honest consultant with 20 years of experience. I'm going to share my [business idea / essay / plan]. Your job is to tear it apart. Find every weakness, every flaw, every assumption I'm making. Don't be polite. After listing the problems, give me a prioritized action plan to fix each one.

This one saved me from launching a terrible landing page. ChatGPT usually says "great idea!" this prompt forces it to actually think critically.

2. The "Learn Anything in 20 Minutes" Prompt

You are an expert teacher who specializes in explaining complex topics to smart beginners. Teach me [topic] using this structure: 1) Explain it like I'm 15 years old in 3 sentences, 2) Now explain the nuance an expert would understand, 3) Give me 3 real-world examples, 4) Give me the 3 biggest misconceptions people have about this, 5) Tell me what to learn next if I want to go deeper.

I used this to understand blockchain, options trading, and cognitive behavioral therapy in one afternoon. The "misconceptions" section is shockingly good.

3. The "Steal My Competitor's Strategy" Prompt

Analyze the brand [competitor name + URL if possible]. Based on publicly available information, break down: 1) Their likely target audience, 2) Their positioning and unique value proposition, 3) Their content strategy and what topics they focus on, 4) Their pricing psychology, 5) 3 weaknesses I could exploit if I were competing with them. Present this as a strategic briefing.

This feels like having a $5,000 strategist in your pocket. I ran this on 4 competitors and found a gap in the market none of them were covering.

4. The "One-Person Marketing Team" Prompt

You are a senior marketing strategist, copywriter, and content planner rolled into one. My product is [describe product, audience, and price]. Create a full 7-day marketing plan that includes: daily social media posts (written out in full, ready to post), 2 email sequences (welcome + sales), 3 hook ideas for short-form video, and a content calendar for the next 30 days. Make everything specific no generic advice.

If you're a solo creator or small business owner, this one prompt replaces hours of planning. The key is giving it enough context about your product.

5. The "Decision Maker" Prompt

I need to make a decision about [describe situation]. Act as a strategic advisor and do the following: 1) List the options I have (including ones I might not have considered), 2) For each option, give me the best-case scenario, worst-case scenario, and most likely scenario, 3) Identify my hidden biases based on how I described the situation, 4) Give me your final recommendation with reasoning, 5) Tell me what question I should be asking myself that I'm not.

That last line "what question should I be asking that I'm not" consistently blows my mind. It catches blind spots I didn't know I had.

6. The "Content Repurposer" Prompt

I have one piece of content: [paste your blog post, video script, or article]. Repurpose it into all of the following: 1) A Twitter/X thread (8-12 tweets, with hooks), 2) A LinkedIn post (professional tone, storytelling format), 3) An Instagram caption (casual, with emojis and CTA), 4) 3 short-form video script ideas (under 60 seconds each), 5) An email newsletter version. Each piece should feel native to the platform not just a copy-paste.

One blog post becomes 7+ pieces of content. I use this every single week.

7. The "Second Brain" Organizer Prompt

I'm going to paste my rough notes, ideas, and scattered thoughts below. Your job is to: 1) Identify the core themes and group them, 2) Turn messy bullet points into clear, actionable items, 3) Highlight the 3 most important ideas and explain why they matter, 4) Suggest connections between ideas I might not have noticed, 5) Create a clean, organized summary I can reference later.

Here are my notes: [paste notes]

I dump my messy voice memos and random notes into this every Friday. It turns chaos into clarity in 30 seconds.

These are just a fraction of the ones I use daily. I've been building a whole system of these organized by category productivity, marketing, writing, business strategy, learning, and more.

Happy to share more if people find these useful. What prompts do you all keep coming back to?
