How to use this library

For Quick Wins:

1. Browse by category — Find the section matching your task
2. Copy the base prompt — Use it as-is or customize the [bracketed placeholders]
3. Run and refine — If output isn't perfect, add constraints or examples
4. Save your winners — Build your personal prompt library from these templates

For Deep Customization:

• Mix and match — Combine techniques (e.g., Role-based + Chain-of-thought)
• Add examples — Include 2-3 examples for few-shot learning
• Set constraints — Define tone, length, format, things to avoid
• Use variables — Create reusable templates with [placeholders]

For Teams:

• Standardize workflows — Choose prompts for common tasks
• Build a team library — Customize prompts for your industry/product
• Train new hires — Use as onboarding resource for AI tools
• Track improvements — Note which prompts work best and iterate

Real-world transformations

Before: Generic prompt

"Help me write content for my website"

After: Using a prompt from this library

"Act as a conversion copywriter. Write 3 variations of homepage hero text for [product]. Target audience: [audience], pain point: [problem]. Each variation should: 1) Lead with benefit not feature, 2) Be under 15 words, 3) Include a power word (transform/unlock/master). Format as: Headline → Subheadline."

Result: Three strong, testable options ready to implement.

Before: Vague coding request

"Check this code for problems"

After: Using a prompt from this library

"Review this Python function for: 1) Time/space complexity issues, 2) Edge cases not handled, 3) Variable naming clarity, 4) Potential bugs. For each finding, rate severity (High/Medium/Low) and provide refactored code example."

Result: Actionable, prioritized feedback with working solutions.

What makes these prompts work

Every prompt in this library follows proven patterns:

• Context first — Gives AI the background it needs
• Clear role assignment — Sets expertise level and perspective
• Specific task definition — No ambiguity about what to produce
• Output format specified — Ensures usable results
• Constraints included — Prevents common errors and off-topic responses

These aren't random prompts we Googled. They're patterns we've tested across ChatGPT, Claude, Gemini, and other major LLMs—refined through hundreds of iterations.

Advanced techniques explained

Chain-of-Thought Prompting

Force AI to show its reasoning before answering. Improves accuracy on complex problems.

Base template:

"Think step-by-step. Before answering [question], explain your reasoning process: 1) What factors matter? 2) How do they relate? 3) What's your conclusion and why?"

Role-Based Expert Consultation

Give AI a specific expertise and perspective to embody.

Base template:

"Act as a [specific role] with [years] of experience in [domain]. Given [context], how would you approach [task]? Consider [constraints] and provide [output format]."

Self-Critique and Refinement

Have AI generate output, critique it, then improve it.

Base template:

"[Initial task]. After completing, review your answer for: [criteria]. Then provide an improved version that addresses any issues found."

Multi-Step Workflows

Break complex tasks into sequential prompts.

Base template:

"This is a 3-step task. ONLY complete Step 1 now: [first task]. Wait for my feedback before proceeding to Step 2."
