Prompt Library

10 expert prompts, ready to copy.

Each prompt is structured with a role, objective, constraints, and output format — so you get professional results without spending 20 minutes on setup. Works with ChatGPT, Claude, and Gemini.

Prompt Engineering

The General Optimizer

Turn a rough idea into a precision-engineered prompt.

Use when: You have a one-sentence idea and need the AI to build it into a structured, high-performance prompt.

Act as an expert Prompt Engineer. I will give you a rough, basic prompt. Your job is to transform it into a highly effective, context-rich, structured prompt that gets premium results from any large language model.

When rewriting the prompt, apply these improvements:
1. Define a clear expert role and persona for the model.
2. Provide explicit context and objective goals.
3. Write clear, step-by-step execution instructions.
4. Add constraints: what to avoid, tone boundaries, and length limits.

Here is the basic prompt to optimize:
"[Insert your basic prompt here — e.g., 'Write an email template asking for a client review']"

Deliver the optimized prompt inside a clean, copy-pasteable code block. Below the code block, explain 2–3 specific improvements you made and why each one matters.

The Persona Builder

Engineer a hyper-realistic AI expert identity.

Use when: You need an AI to fully inhabit a specific expert role — with distinct communication habits, mental frameworks, and hard limits.

You are a Master AI Architect specializing in persona design. I need you to engineer a comprehensive, deeply layered system persona for an AI assistant.

The core role I want to create is: [Insert role — e.g., "A ruthless copy editor who specializes in tightening tech resumes"]

Output a structured system prompt with the following sections:

- Role & Background: Who this persona is, their years of experience, and their precise area of expertise.
- Communication Style & Tone: How they speak (e.g., blunt, encouraging, academic, corporate) and any specific vocabulary preferences or restrictions.
- Mental Frameworks: The methodologies, rules of thumb, and analytical lenses they use to evaluate information.
- What to Avoid: Behaviors, overused clichés, and conversational filler this persona would never use.

Format the final output as a clean, ready-to-deploy system prompt inside a markdown code block.

The Few-Shot Generator

Build example pairs that teach the AI exactly what you want.

Use when: You need the AI to match a very specific output style or format — and examples will get you there faster than instructions alone.

I am building a few-shot prompt to train an AI on a highly specific task. I need high-quality, realistic input/output example pairs.

The specific task is: [Insert task — e.g., "Extracting action items from chaotic meeting transcripts and assigning each a priority level"]

Generate three distinct, realistic example pairs for this task:
- Example 1: A standard, straightforward scenario.
- Example 2: A complex or messy scenario that shows how to handle edge cases.
- Example 3: A brief or sparse scenario with minimal input data.

Format each example exactly like this so I can drop it directly into my final prompt:

### Example [Number]
Input: [Realistic mock data]
Output: [The ideal, perfectly structured response]

The Reasoning Injector

Force the AI to think before it answers.

Use when: You have a complex, logic-heavy, or analytical task where the AI keeps skipping steps and producing flawed output.

I have a complex prompt that requires rigorous logical analysis, but the AI keeps skipping critical reasoning steps and delivering flawed answers. Modify this prompt to inject a Chain-of-Thought reasoning scaffold.

Rewrite the prompt so the model is forced to do the following before providing any final answer:
1. Break the problem into its core components.
2. List all constraints and hidden assumptions it must respect.
3. Walk through its logic step-by-step in a designated Reasoning phase, using markdown blockquotes.
4. Verify its logic against the constraints before committing to the final output.

Here is the prompt that needs the reasoning injection:
"[Insert your prompt — e.g., 'Analyze this marketing data and identify which channel has the best risk-adjusted return']"

Deliver the redesigned prompt in a clean, copy-pasteable format.

The Output Structurer

Lock down the format. Zero fluff, zero filler.

Use when: You are feeding AI output into an automation, data pipeline, or dashboard and need a guaranteed structure — no conversational filler.

I need to enforce a strict output structure for a prompt so it fits directly into my workflow. No conversational introductions, no meta-commentary, no pleasantries.

The core task is: [Insert task — e.g., "Summarizing customer support tickets into core themes"]

Rewrite this task as a prompt that mandates a strict output format. The prompt must include:
1. A clear declaration of the target format: [Specify — e.g., a Markdown table / valid JSON matching a specific schema / bulleted headers].
2. Absolute constraints banning any introductory phrases, filler text, or conversational wrappers.
3. Fallback instructions specifying exactly what to output if the input data is missing, corrupted, or invalid — e.g., return `null` or an empty table row.

Deliver the final, locked-down prompt in a clean code block.

Power Prompts

Universal Prompt Optimizer

Diagnose any prompt, then rebuild it from first principles.

Use when: You have an existing prompt that isn't performing and want a systematic analysis before rewriting it.

You are a world-class Prompt Engineer specializing in optimizing prompts for large language models.

Analyze and improve the prompt provided below.

Before rewriting, complete the following analysis:
1. Identify the user's true objective.
2. Identify missing context.
3. Identify ambiguities or assumptions.
4. Identify potential failure points.
5. Note any additional information that would improve results.

Then rewrite the prompt using this framework:
- Role
- Objective
- Context
- Constraints
- Desired Output Format
- Examples (if beneficial)
- Success Criteria

Structure your response in four sections:

SECTION 1: Prompt Analysis
SECTION 2: Missing Information
SECTION 3: Optimized Prompt
SECTION 4: Additional Recommendations

Frequently asked questions

What is a prompt library?

A prompt library is a curated set of reusable, structured prompts designed to get consistent, high-quality outputs from AI models like ChatGPT, Claude, and Gemini. Each prompt in Promptivo's library includes a role definition, objective, constraints, and output format so you can copy, fill in your variables, and get professional results immediately.

Which AI models do these prompts work with?

Every prompt in this library works with ChatGPT (GPT-4o), Claude, and Gemini. For best results, use Promptivo's Build tool to generate a version tuned to your specific model.

What makes a good AI prompt?

A good AI prompt defines a clear expert role, states the objective explicitly, provides relevant context, sets constraints (what to avoid, tone, length), and specifies the desired output format. The prompts in this library follow this structure so you get predictable, professional results.

How do I use these prompts?

Click the Copy button on any prompt, paste it into your AI tool of choice, replace the bracketed placeholders (e.g. [INSERT TOPIC]) with your actual content, and send. Each prompt is self-contained — no extra setup required.
