# Prompt Genie > Prompt optimizer that rewrites rough prompts for ChatGPT, Claude and Gemini and stores them in a library. Prompt Genie is a tool that rewrites a rough idea into a detailed prompt before it reaches an AI model. Users type a request, refine the optimised version, then open it in ChatGPT, Claude or Gemini or compare outputs across models. Prompt Genie also offers a prompt library, a Chrome extension and context memory for Claude Code. **Best for:** Individuals and small teams who write many prompts and want them optimised, stored and shared in one place. - Official site: https://www.prompt-genie.com - Listed in: [Large Language Models & Prompts](https://trendhub.net/ai-tools/category/large-language-models), [Productivity & Team Work](https://trendhub.net/ai-tools/category/productivity-tools) - Last checked: 2026-10-09 (facts taken from prompt-genie.com) - Source page: https://trendhub.net/ai-tools/prompt-genie-optimizer-library ## Key facts - Platforms: Web, Browser extension, API - Pricing model: Freemium - Free plan: Yes - API: Yes ## What is Prompt Genie? Prompt Genie is a prompt optimisation tool that rewrites a rough request into a more specific prompt before it is sent to a language model. You type an idea in plain English, the tool expands it into what it calls a Super Prompt, and you can adjust tone, context and detail before sending. The result opens directly in ChatGPT, Claude or Gemini, or can be run against several models side by side to compare answers. Finished prompts are saved in a library, and a feature named Context Genie stores background information once so it is applied to later prompts. A Chrome extension places the optimiser inside those chat interfaces. A newer command-line component for Claude Code keeps track of files already read in a session to avoid resending them. A limited free tier exists alongside paid individual and team plans. ## Key features - **Super Prompts**: Expands a short plain-language idea into a detailed prompt tailored to the task. - **Prompt Library**: Stores prompts that worked so they can be reused, organised and shared with teammates. - **Context Genie**: Remembers details about you or your business and applies them automatically to new prompts. - **Multi-Model Testing**: Sends one prompt to GPT-4, Claude and Gemini together and shows the outputs next to each other. - **Chrome Extension**: Adds an optimise button inside the ChatGPT, Claude and Gemini web interfaces. - **Claude Code Context Memory**: Runs locally via `npx prompt-genie` and serves previously read files from context to reduce repeat token use. ## How Prompt Genie works 1. **Type the idea**: Describe what you need in ordinary language without special syntax. 2. **Optimise**: Prompt Genie rewrites the idea into a clearer, more specific prompt. 3. **Refine**: Adjust tone, context and level of detail. 4. **Test**: Run the prompt across several models and keep the output you prefer. ## Use cases - **Improving a First Draft Prompt**: Turn a two-line request into a structured prompt before spending tokens on it. - **Team Prompt Standards**: Keep approved prompts in a shared library with version history so everyone uses the same wording. - **Choosing a Model**: Compare how different models answer one prompt and pick the output that fits. - **Reusing Business Context**: Save audience and brand details once instead of retyping them in each conversation. - **Long Claude Code Sessions**: Lower repeated file-reading costs during extended coding sessions. ## Things to know - **Free tier is limited**: The Basic tier allows a single Super Prompt per day and stores at most 15 prompts. - **Team features need the Team plan**: Shared workspaces, role-based permissions, version history and API access are listed for the Team plan, which covers up to five members. - **Lifetime offer is individual only**: The one-time lifetime purchase applies to the individual Pro plan; team plans remain subscriptions. - **Separate setup service**: A done-for-you service called Genie Concierge, which sets up AI workflows for a business, is offered apart from the app. ## FAQs ### What is Prompt Genie?
