Hacking AI: System Prompts and Templates

AI doesn't deliver poor results. You ask poor questions. The difference between a professional who extracts 10x more from ChatGPT, Claude, and Gemini and someone who receives generic answers is not in the tool — it's in the prompt. This guide will teach you how to hack AI with system prompts, ready-made templates, and prompt engineering for marketing, sales, content, and productivity.

If you've ever been frustrated with vague, generic, or irrelevant AI responses, the problem is the same as always: bad input = bad output. Think of AI as a brilliant intern — if you don't provide context, persona, and format, it will improvise. Poorly.

The Problem: Generic Questions Generate Generic Answers

See the difference between a random prompt and a professional prompt:

❌ Generic Prompt

"Help me sell more."

Typical response: "To sell more, improve your marketing, create promotions, and train your team."
— Generic, useless, sounds like it came from Wikipedia.

✅ Professional Prompt

"Act as a B2B marketing director. I have a monthly budget of R$5,000, an average ticket of R$1,200, and 80 leads/month with a conversion rate of 3%. Create a 30-day action plan to double the conversion rate. Prioritize low-cost tactics. Format: table with action, channel, effort, and estimated impact."

Response: a concrete, prioritized, and executable action plan.

The difference lies in 5 elements that most people ignore: persona, context, goal, format, and constraints.

The Ultimate System Prompt: The "Template" That Transforms Any AI

There is a shortcut that few people use: custom instructions (or system prompt). Instead of repeating context throughout the conversation, you set it up once and the AI maintains the behavior in all subsequent interactions.

Copy the text below and paste it into the custom instructions of your tool (ChatGPT, Claude, or Gemini):

## YOUR PROFILE
Before responding, always consider:
- Who I am: [describe yourself — e.g., marketing director of a B2B SaaS with 20 employees]
- My market: [your sector]
- My audience: [your main persona]
- My main goal: [e.g., generate qualified leads, reduce CAC, scale content]

## GOLDEN RULES
1. NEVER respond without first asking diagnostic questions if I haven't provided enough context.
2. ALWAYS challenge my ideas with undeclared risks and blind spots — don't be a sycophant.
3. ALWAYS deliver in the format I request (table, list, bullet, short paragraph).
4. Use a direct tone, without corporate fluff, no long introductions.
5. If I ask for content, prioritize strong hooks, short sentences, and clear CTAs.
6. If I ask for analysis, be skeptical — point out what's wrong, not just what's right.
7. If you don't know or don't have data, say "I don't know" instead of making something up.

## ITERATION
- If my question is vague, ask me: what is the goal, audience, channel, and constraint?
- If I ask "improve," tell me what specifically improved and why.
- If I ask "summarize," keep only what is actionable.

This takes 2 minutes to set up. And it changes everything.

10 Ready-to-Use Prompts for Productivity and Marketing

Each template below is copy, paste, adapt the brackets, and use. Tested on ChatGPT, Claude, and Gemini.

1. Business Diagnosis (before asking anything)

Act as a business consultant. My business is [describe]. My current numbers: [revenue, average ticket, CAC, main channels]. I want [goal]. Before giving me any answer, ask me 5 diagnostic questions that I am not asking.

2. Content Brief That Ranks

You are an SEO strategist. For the topic [TOPIC] and main keyword [KEYWORD], create an article brief with: search intent, target audience, optimized title (max 60 chars), 2 alternative subtitles, H2/H3 structure, meta description (max 160 chars), 5 questions the reader would ask, recommended CTA, and 3 related content ideas for clustering.

3. Objection Analysis (sales)

Analyze this sales conversation and be critical: 1) What is the real undeclared objection? 2) At what point did I lose the lead? 3) What should I have responded differently?

[PASTE THE CONVERSATION]

4. Cold Lead Follow-Up (revive lead)

This lead requested a quote [X] days ago and disappeared. Write a follow-up that: generates curiosity, doesn't seem desperate, gives a new reason to respond now, and is a maximum of 3 lines. Tone: direct and personal, as if it were a WhatsApp message.

5. Magnetic Post for Instagram/LinkedIn

Create a post for [SOCIAL NETWORK] about [TOPIC]. Rules: 1st sentence = controversial or curious hook, max 150 words, conversational tone (nothing corporate), 1 clear CTA at the end, 3 relevant hashtags. Give me 2 options with different angles.

6. Prospecting Email That Converts

Write a cold email for [POSITION] of companies [SEGMENT]. Maximum 120 words. Structure: opening with industry pain, presentation of the solution in 1 line, 1 social proof or concrete data, CTA with a question that invites a response. No corporate introductions. Tone: direct but not aggressive.

7. Executive Summary of Meeting

Turn these meeting notes into a professional minutes. Format: Date, Participants, 3 Main Decisions, Next Steps (with responsible + deadline for each), Points of Attention.

[PASTE THE NOTES]

8. Prioritized Action Plan (Eisenhower Matrix)

I am [POSITION] and I have these tasks: [LIST]. Use the Eisenhower Matrix to classify into: Urgent+Important, Important+Not Urgent, Urgent+Not Important, Not Urgent Not Important. Then, create an execution order for my day from [TIME X] to [TIME Y], prioritizing quadrant 1.

9. Short Video Script (Reels/TikTok)

Create a script for a 60-second video about [TOPIC]. Audience: [AUDIENCE]. Platform: [TikTok/Reels]. Structure: 0-3s impressive hook, 3-50s development with 3 points, 50-60s CTA + closing statement. Tone: fast, dynamic, zero introduction.

10. Idea Critic (the most underrated)

Act as a skeptical customer. Critique this proposal/idea as if you were making the buying decision. Point out: 1) What would make you say NO, 2) Undeclared risks, 3) What is missing to be convincing. Be tough — I prefer criticism now than losing the sale later.

The 7 Prompt Engineering Techniques No One Teaches You

1. Flip the Game: Ask Questions, Not Answers

Add this phrase at the end of any complex prompt: "Before responding, ask me the questions you need to deliver the best possible answer." This forces the AI to ask for context before guessing — the results improve drastically.

2. Chain of Thought

For complex problems, use: "Think step by step before responding." — the AI structures reasoning and reduces hallucinations. Essential for financial analyses, strategies, and diagnostics.

3. Create an Internal Critic

Ask: "After responding, review your own answer as a skeptical expert. Point out weaknesses and what could be improved." The AI applies self-criticism and delivers a refined version.

4. Few-shot Prompting

If you have examples of the format you want, show 2-3 before. E.g., "Here are 2 headlines that worked well. Create 5 in the same style." The AI understands the pattern much better than with abstract instructions.

5. Rapid Iteration

The first response is a draft. Command with a word: "Simplify", "More direct", "Remove corporate tone", "In 3 bullets", "Explain as if I were 12 years old". Each iteration refines exponentially.

6. Creative Restriction

Limits generate better results. "Maximum 100 words", "In 3 impactful sentences", "No adjectives", "Prohibited from using the words: solution, innovative, disruptive". The restriction forces the AI to be precise.

7. Multi-Perspective

For strategic decisions: "Analyze this decision from the perspective of: 1) CEO focused on revenue, 2) Marketing Director focused on brand, 3) Customer focused on cost-benefit." You receive 3 complementary analyses in a single prompt.

5 Mistakes That Ruin Your AI Results

Error	Why It Destroys the Output	How to Fix It
1. One-Line Prompt	The AI fills gaps with assumptions — and gets it wrong	Minimum: persona + goal + format
2. Not Defining Persona	The AI responds as a "generic assistant", not as a specialist	Always start with "Act as [specialist]"
3. Accepting the First Response	The AI's first response is a draft, not the final version	Iterate at least 2x with refinement commands
4. Not Providing Examples	The AI has no reference for your quality standard	Paste 1-2 examples of what you consider good
5. Not Using Custom Instructions	You repeat the same context every time — and forget half	Set up the system prompt once and stop repeating

What Happens When You Master Prompts

Professionals who implement system prompts and prompt engineering report:

3x more speed in content production (brief → draft → refinement in minutes, not hours)
2x more effective sales responses — because the AI qualifies objections before you send
80% less rework in emails, posts, and proposals — the first draft already comes in the right tone
Strategic diagnostics that previously required hours of meetings — in 1 well-structured prompt

It's not about the tool. It's about how you ask.

Frequently Asked Questions

Does the system prompt work on any AI?

Yes. ChatGPT, Claude, Gemini, Copilot, and DeepSeek accept custom instructions. The format may vary slightly (some call it "custom instructions", others "system prompt"), but the logic is the same.

Do I need to pay to use custom instructions?

No. Custom instructions are available in all plans, including free, on ChatGPT, Claude, and Gemini.

What is the difference between a system prompt and a normal prompt?

The normal prompt applies to one conversation. The system prompt (custom instructions) is permanent — the AI follows the rules in all conversations without you needing to repeat. It's like setting up the "operating system" of the AI once.

Can I use the same system prompt for different tasks?

Yes. A good system prompt defines your profile, tone of voice, and general rules. For specific tasks (e.g., writing a sales email), you complement it with the task prompt. The system prompt is the base; the task prompt is the specific command.

Can I modify the prompt templates?

Of course. The templates are starting points. Adapt the tone, add specific market restrictions, and refine as you use. The best prompt library is the one you built by testing.

How do I know if my prompt is good?

Simple rule: if the AI responded exactly in the format and depth you needed on the first attempt, your prompt was good. If it took 3+ iterations to get close, the prompt was weak. Measure by the number of iterations until the final result.

Do these prompts work for SEO content creation?

Yes. Prompt #2 (Content Brief) was specifically designed for SEO. Combine it with your knowledge of search intent, and you'll have briefs that generate rankable content. Explore more about SEO and content marketing on the Kaizen blog.
