Chrome ExtensionChatGPT Prompt Generator
Generate optimized prompts for ChatGPT using proven prompt engineering best practices. Fill in your task, role, context, and constraints — and let AI craft the perfect prompt for GPT-4o, o1, o3-mini, and more.
Be specific about what you want the AI to do
Generated Prompt
Fill in the form and click "Generate" to create an optimized ChatGPT prompt.
Tip: The more specific your task description and context, the better the generated prompt will perform.
ChatGPT Tips
- • Start with a clear role assignment: "You are a [specific expert]" dramatically improves quality
- • Add constraints like word limits and format rules to keep outputs focused
- • For complex tasks, add "Think step by step" to enable chain-of-thought reasoning
- • GPT-5 and GPT-4o work best with structured instructions; o3/o4-mini reasoning models need less hand-holding
How to Use the Prompt Generator
Define Your Task
Select a task category, describe what you want ChatGPT to do, and assign a role or persona. The more specific you are, the better the generated prompt will perform.
Set Context & Constraints
Add background context, choose your desired tone and output format, specify your target audience, and set any constraints like word limits or things to avoid.
Generate & Use
Click "Generate" to get an optimized prompt following best practices. Copy it and paste directly into ChatGPT for dramatically better results.
Frequently Asked Questions
What is a ChatGPT prompt generator?
A ChatGPT prompt generator helps you create optimized, well-structured prompts that produce better results from ChatGPT. Instead of writing vague requests, it structures your inputs into prompts that follow proven prompt engineering best practices — including role assignment, context setting, output formatting, and constraint specification.
How does this tool improve my ChatGPT results?
It applies the five core principles of effective prompting: clarity over creativity, context as a control mechanism, consistency through templates, constraints to improve quality, and iterative refinement. The generated prompt combines role-based prompting, chain-of-thought reasoning, and format constraints for optimal results.
What's the difference between GPT-4o, o1, and o3-mini?
GPT-4o is OpenAI's flagship model — fast, multimodal, and great with structured instructions. o1 and o3 are reasoning models that "think" before answering — they excel at math, logic, and complex analysis but need less hand-holding in prompts. o3-mini and o4-mini offer reasoning capabilities at lower cost and faster speed.
Is this tool free to use?
Yes! You get 3 free prompt generations per day with no signup required. For unlimited access, sign up for a Promptslove membership which includes all AI tools and 20,000+ premium prompts.
Can I use these prompts with other AI models?
While optimized for ChatGPT, the generated prompts follow universal prompt engineering principles and work well with Claude, Gemini, Grok, and other large language models. The core techniques (role assignment, context, constraints) are model-agnostic.
What makes a good ChatGPT prompt?
A good ChatGPT prompt has five elements: a clear role/persona, specific task description, relevant context, defined output format, and explicit constraints. Adding these elements systematically produces dramatically better results than vague, open-ended questions.
Should I use chain-of-thought prompting?
Yes, for analytical, mathematical, or multi-step tasks. Adding "Think step by step" or "Reason through this before answering" encourages the model to show its reasoning process, reducing errors and making outputs easier to verify. This is especially effective with reasoning models like o1 and o3.
How many prompts can I generate for free?
You get 3 free prompt generations every 24 hours. This resets automatically. For unlimited generations, consider signing up for a Promptslove membership.
