How It Works
Write Your Prompt
Type or paste a basic prompt describing what you want the AI to do. It can be as simple as a single sentence.
Choose a Framework
Select from 17 prompt engineering frameworks across persona, technique, and structure categories. Add optional sliders and custom instructions.
Get Expert Instructions
Receive a structured, detailed prompt engineered for maximum AI output quality. Copy and paste it into ChatGPT, Claude, Gemini, or any AI tool.
Tips for Best Results
Be specific about your goal
"Write a cover letter for a senior React developer role at a fintech startup" beats "Write a cover letter".
Include context
Mention the audience, industry, or constraints. The more context, the better the enhanced prompt.
Use enhancement sliders
Expand the Enhancement Techniques section to fine-tune specificity, tone, examples, and more.
Iterate and refine
Try different frameworks on the same prompt to see which produces the best structure for your needs.
Framework Guide
Each framework shapes your prompt in a different way. Pick one that fits the kind of output you need.
Persona Frameworks
These give the AI a specific role and personality. They work well when you want a particular voice, expertise level, or point of view in the response.
OCEAN
Structures prompts around observable behaviors, concrete details, and narrative. Good for storytelling, case studies, and content that needs to feel vivid and grounded.
OCEAN-RPi
An educational variant of OCEAN. Sets a clear objective, provides context and examples, then asks the AI to assess and negotiate the best approach. Good for tutorials and explanations.
RISEN
Assigns a role, gives step-by-step instructions, defines the end goal, and sets boundaries. A solid all-purpose framework for most tasks.
CO-STAR
Covers context, objective, style, tone, audience, and response format. Works well for marketing copy, emails, and anything where tone and audience matter.
RTF
The simplest persona framework. Just role, task, and format. Use it when you want a quick enhancement without a lot of structure.
Technique Frameworks
These control how the AI thinks and reasons. They shape the process of getting to an answer, not just the format of it.
Chain of Thought
Tells the AI to reason step by step before giving an answer. Good for math, logic, analysis, and anything where showing the work matters.
Tree of Thought
Explores multiple solution paths and picks the best one. Useful for complex problems where the first approach might not be the right one.
Few-Shot
Adds concrete examples to the prompt so the AI knows exactly what format and quality you expect. Works well when you have a specific output style in mind.
Zero-Shot
Gives crystal-clear instructions without examples. Relies on precise wording to get the right output. Good when examples would be hard to write or unnecessary.
Step-by-Step
Breaks the task into numbered steps the AI should follow in order. Good for processes, how-to guides, and multi-part tasks.
Role Prompting
Assigns a specific expert identity to the AI. Different from persona frameworks in that it focuses purely on expertise, not on prompt structure.
SCAMPER
A creative thinking method. Asks the AI to substitute, combine, adapt, modify, put to other uses, eliminate, and reverse. Good for brainstorming and innovation tasks.
Structure Frameworks
These organize the prompt around a specific narrative or logical structure. They work best when the shape of the output matters as much as the content.
PAR
Problem, Action, Result. A clean three-part structure for describing issues and solutions. Works well for case studies and project summaries.
STAR
Situation, Task, Action, Result. Adds more context than PAR by separating the situation from the specific task. Good for technical specs and detailed plans.
5W1H
Who, What, When, Where, Why, How. Covers all angles of a topic. Good for research prompts, reporting, and thorough analysis.
Before-After-Bridge
Describes the current state, the desired state, and the path between them. Natural fit for transformation stories, proposals, and persuasive writing.
Input-Process-Output
Defines what goes in, what happens to it, and what comes out. Good for technical documentation, data processing tasks, and system design prompts.
Secondary Technique
You can combine any primary framework with a secondary technique from the dropdown. The secondary technique layers additional reasoning or creative methods on top of the primary structure.
For example, RISEN + Chain of Thought produces a role-based prompt that also requires step-by-step reasoning. STAR + Few-Shot creates a structured scenario with worked examples.
Not every combination is necessary. Start with just a primary framework. Add a secondary technique when the output needs a specific reasoning style or when a single framework doesn't cover everything you need.
