GPTPromptMaker is a web-based prompt generator and prompt library for people who use AI chat tools such as ChatGPT, Claude and Gemini. It turns a short idea into a structured prompt using established prompt engineering frameworks, and it offers more than 500 templates that can be copied or customized.
The site's premise is that standard prompts fail because they lack structure. Instead of leaving a model to guess at intent, audience and format, GPTPromptMaker sets the role, context, constraints and output format up front. It also includes a Chrome extension, a prompt scorer and several free tools that need no login.
Users describe what they want, and the generator formats the request with one of three named frameworks: CO-STAR (Context, Objective, Style, Tone, Audience, Response), RISEN (Role, Instructions, Steps, End Goal, Narrowing) or CRAFT (Context, Role, Action, Format, Target Audience). The company positions CO-STAR for marketing, RISEN for coding and reasoning, and CRAFT for business documents.
The GPM Chrome Extension adds an Improve button inside ChatGPT, Claude, Gemini and Perplexity. A user types a basic idea, clicks Improve, and the extension rewrites it as a prompt with variable placeholders and recommended models. Generated prompts are described as model-agnostic, so they can be pasted into other supported tools.
The prompt library holds 500+ templates across categories including Marketing, Copywriting, Email, Social Media, Sales, Coding, Data Analysis, Legal & Compliance, HR & Talent Acquisition, E-commerce & Retail, Finance and Product Management. Templates can be copied directly or customized. A Prompt Scorer rates clarity and specificity, which helps users check a draft before running it.
Free tools include the Prompt Generator, Prompt Scorer, an AI Content Checker that analyzes originality and patterns, and an AI Idea Generator for hooks and topic ideas. Paid plans add a Prompt Vault for saving and editing prompts, optimal model suggestions and unlimited use of the Chrome extension.
