Engineered with Battle-Tested Prompt Frameworks
Why do standard AI prompts fail? Because they lack structure. GPTPromptMaker systematically formats your instructions using industry standard frameworks.
CO-STAR Framework
Context, Objective, Style, Tone, Audience, Response.
Eliminates generic AI responses by anchoring the model into a precise persona, audience perspective, and desired output deliverable.
RISEN Framework
Role, Instructions, Steps, End Goal, Narrowing.
Designed for multi-step reasoning, algorithms, debugging, and strict constraints (what NOT to do) to prevent hallucinations.
CRAFT Framework
Context, Role, Action, Format, Target Audience.
Perfect for corporate deliverables: executive memos, board slide outlines, standard operating procedures, and risk assessments.

Frequently Asked Questions
What makes GPTPromptMaker different from typing directly into ChatGPT?
When you ask an AI model a question directly without structure, it makes wild assumptions about your intent, audience, and formatting. GPTPromptMaker uses proven prompt engineering frameworks (CO-STAR, RISEN, CRAFT) to explicitly set the role, context, negative constraints, and output schema, drastically reducing hallucinations and trial-and-error.
Does this work with Claude, Gemini, Copilot, and Perplexity?
Yes. All prompts generated by GPTPromptMaker and our GPM Chrome Extension are model-agnostic. They work seamlessly across OpenAI ChatGPT (GPT-4o, o3-mini), Anthropic Claude (Claude 3.5 Sonnet), Google Gemini (Gemini 2.5 Pro/Flash), Microsoft Copilot, and Perplexity AI.
How does the GPM Chrome Extension work?
The GPM Extension adds an "Improve" button directly inside ChatGPT, Claude, Gemini, and Perplexity chat interfaces. You type your basic idea, click Improve, and the extension instantly transforms it into a production-grade prompt with variable placeholders and recommended models.
Can I start for free?
