November 21, 2025 — Mike
Google’s Gemini 3.0 Pro just dropped, and the AI world is on fire. Robert’s thread breaks down 10 pro-level prompts that feel like straight-up cheating— from McKinsey reports to no-code apps. Min’s follow-up shows the mind-blowing agentic demos breaking the internet. And that reply? Pure indie hacker fire.
I used Robert’s #2 prompt to build a competitor dashboard in 3 hours flat. Sharing the full embed below, plus the threads for context. Let’s build.

Gemini 3.0 Pro is dangerously good.
But 99% of people are sleeping on what it can actually do.
I’ve used it to build apps, generate content, automate deep research, and more.
Here are 10 ways to use Gemini 3.0 Pro that feel like cheating:
1/11
1. Automated research reports (better than $100k consultants)
Gemini real-time web search and analytical reasoning let you replicate what McKinsey, Gartner, or Deloitte charge six figures for.
Prompt to use with Gemini:
“You are a world-class strategy consultant trained by McKinsey, BCG, and Bain. Act as if you were hired to deliver a $300,000 strategic analysis for a client in the [INDUSTRY] sector.
Mission
1. Analyze the current state of the [INDUSTRY] market.
2. Identify key trends, emerging threats, and disruptive innovations.
3. Map the top 3-5 competitors and benchmark their business models, strengths, weaknesses, pricing, distribution, and brand positioning.
4. Apply SWOT, Porter’s Five Forces, and value-chain analysis to assess risks and opportunities.
5. Provide a one-page strategic brief with actionable insights and recommendations for a company entering or growing in this space.
Return everything in concise bullet points or tables, ready to paste into slides. Think like a McKinsey partner preparing for a C-suite meeting.”
2/11
2. Build interactive tools and apps without code
Describe your idea and Gemini scaffolds the UI, logic, and deployment steps—no coding required.
Prompt:
“You are a senior software architect who excels at building no-code and low-code systems with HTML, JavaScript, and Web APIs.
Task
Design a fully working interactive tool based on this idea:
[DESCRIBE YOUR TOOL IDEA]
Deliverables
1. A plain-English explanation of how the tool works.
2. A step-by-step plan to implement it with Gemini or a no-code platform.
3. Exact HTML/CSS/JS code if relevant.
4. UX and design improvement tips.
5. Instructions to generate a shareable, embed-ready version.
Imagine you are shipping an MVP for a startup demo.”
3/11
3. Generate infographics from plain text
Feed any concept and Gemini turns it into a clean Mermaid.js or SVG diagram—no Figma or Canva needed.
Prompt:
“You are a world-class visual explainer and technical designer.
Transform this concept into a visual infographic using Mermaid.js or another code-based diagram format:
“[INSERT CONCEPT]”
Return
1. A flowchart, timeline, concept map, or decision tree—whichever fits best.
2. A plain-language caption explaining the graphic.
3. Clean Mermaid (or HTML/SVG/CSS) code I can copy and render.
Keep it minimal, readable, and slide-ready.”
4/11
4. Create McKinsey-style web presentations
Gemini structures decks using the pyramid principle, then wraps them in responsive HTML you can share instantly.
Prompt:
“Act as a strategy consultant creating a web-based presentation.
Topic: [INSERT TOPIC]
Output
1. Use the pyramid principle: Problem → Insight → Recommendation.
2. Break into 6–10 concise slides, each with a bold title and 2–4 bullets.
3. Provide mobile-responsive HTML/CSS for the deck (optional).
4. Focus on clarity, insight, and executive readiness.
Make it feel like a McKinsey slide deck built in Beautiful.AI”
5/11
5. Replace your tutor
Gemini teaches like an expert mentor—step by step, at your pace.
Prompt:
“You are a world-class private tutor.
Teach me [TOPIC] as if I’m a motivated beginner.
Include
1. A structured lesson plan divided into digestible parts.
2. Analogies and step-by-step explanations.
3. Practice questions with answers.
4. A short summary after each section.
Teach in a warm, Socratic tone and pause for understanding checks before advancing.”
6/11
6. Content creation… newsletters, threads, YouTube scripts
Gemini mimics tone, nails structure, and writes content people care about.

“You are a top-tier content strategist and writer.
Task
Write a [TYPE OF CONTENT: newsletter, tweet thread, YouTube script, etc.] on:
“[INSERT TOPIC]”
Guidelines
1. Mirror the tone and style of [CREATOR OR BRAND].
2. Use hooks, smooth transitions, and emotional triggers.
3. Make it actionable, conversational, and valuable.
4. Suggest a title and a strong CTA at the end.
The result should feel human, not AI-generated.”

“[DESCRIBE BUSINESS PROBLEM OR IDEA]”
