# Prompt Pro — Full Reference > Write lazy prompts. Get expert answers. Free Chrome extension that rewrites rough prompts into detailed, expert-level ones inside ChatGPT, Claude and Gemini. ## What is Prompt Pro? Prompt Pro (http://trypromptpro.com) is a Chrome extension that fixes the biggest everyday AI problem: the gap between what you type and what the AI needs to give a great answer. Instead of teaching you prompt engineering, it does the engineering for you. You write a rough prompt in ChatGPT, Claude or Gemini, click the Prompt Pro button, and in about two seconds your prompt is rewritten as a detailed, structured, expert-level prompt — role, context, constraints, output format included. You review it and hit send. ## How it works 1. Install the extension from the Chrome Web Store: https://chromewebstore.google.com/detail/prompt-pro-ai-prompt-enha/fmdkfimgcpkjcibklbachcnknllgoaaj 2. Open ChatGPT, Claude, Gemini, Google AI Studio or Perplexity as usual. 3. Type your rough prompt and click the Prompt Pro enhance button that appears in the input. 4. Your prompt is transformed in place — edit if you like, then send. No copy-pasting between tools, no prompt templates to memorize, no separate app. ## Plans and pricing - Free: $0 forever — 3 enhancements per day (credits reset at midnight), all supported platforms. - Pro: $4.99/month or $39/year — unlimited enhancements and prompt history. Payments are processed by Stripe. Cancel anytime. ## Privacy and security Prompts are encrypted in transit and at rest. Prompt Pro never trains models on your prompts. Infrastructure providers are SOC 2 compliant. ## Frequently asked questions Q: Is there a free plan? A: Yes — 3 free enhancements every day, forever. If you need more, Pro gives unlimited enhancements for $4.99/month. Q: Which AI platforms does it work with? A: ChatGPT, Claude, Gemini, Google AI Studio and Perplexity, with more being added. Q: Do I need to know prompt engineering? A: No — that's the point. Prompt Pro applies the structure experts use (role, context, constraints, format) automatically. Q: Is my data secure? A: Yes. Encrypted in transit and at rest, never used for training. ## Free prompt library A growing library of copy-ready expert prompts at http://trypromptpro.com/prompts: - Cold email: http://trypromptpro.com/prompts/cold-email - Marketing: http://trypromptpro.com/prompts/marketing - Blog writing: http://trypromptpro.com/prompts/blog-writing - Social media: http://trypromptpro.com/prompts/social-media - Summarizing: http://trypromptpro.com/prompts/summarizing - Job applications: http://trypromptpro.com/prompts/job-applications - Coding: http://trypromptpro.com/prompts/coding - Customer support: http://trypromptpro.com/prompts/customer-support - Product descriptions: http://trypromptpro.com/prompts/product-descriptions - Studying: http://trypromptpro.com/prompts/studying ## Platform guides - Prompt Pro for ChatGPT: http://trypromptpro.com/for/chatgpt - Prompt Pro for Claude: http://trypromptpro.com/for/claude - Prompt Pro for Gemini: http://trypromptpro.com/for/gemini - Prompt Pro for Perplexity: http://trypromptpro.com/for/perplexity - Prompt Pro for Google AI Studio: http://trypromptpro.com/for/ai-studio ## Links - Website: http://trypromptpro.com - Install: https://chromewebstore.google.com/detail/prompt-pro-ai-prompt-enha/fmdkfimgcpkjcibklbachcnknllgoaaj - Concise version for AI: http://trypromptpro.com/llms.txt - Company: ProductShake, LLC — https://productshake.com
