How it works
How it works This template provides a complete, ready-to-use web application for generating high-quality AI prompts. It features a user-friendly web form where you can describe your goal, and it leverages an AI model (Google Gemini) to create a structured, reusable prompt for you. The workflow is a full-stack application built entirely within n8n: Frontend (The Form): A Form Trigger node creates a beautiful, public-facing web form. Here, a user describes the prompt they need and selects which structural components to include (like system instructions, examples, or input variables). Backend (The AI Logic): A LangChain Chain node takes the user's request and constructs a "meta-prompt"—a set of instructions for the AI on how to generate the final prompt. The Google Gemini node executes this meta-prompt, creating a well-structured output with clear sections and tags. The Result (The Webpage): After generation, the user is automatically redirected to a new URL. This URL is handled by another Webhook node, which serves a custom-coded HTML page. This beautiful, dark-themed webpage displays the generated prompt and includes a one-click "Copy" button, making it easy to use the result immediately. This template is a perfect example of how to build interactive web tools with n8n, combining a user interface, backend logic, and a dynamic web response in a single workflow. Set up steps Setup time: ~1-3 minutes This workflow requires a Google AI credential to function. Configure Google AI Credentials: This workflow uses a Google Gemini model. You will need a Google AI API key. In n8n, go to Credentials and click Add credential. Search for Google Gemini and enter your API key. Go back to the workflow, open the Gemini 2.5 Flash node, and select your newly created credential from the dropdown. Activate the Workflow: Click the Active toggle in the top-right corner to turn the workflow on. Access Your Prompt Maker: Open the Prompt Request (Form Trigger) node. Copy the Public URL provided. This is the link to your new web application! Open the link in your browser, fill out the form, and see the magic happen. Note: This workflow uses environment variables like {{ $env.WEBHOOK_URL }} to build the redirect URL. These are typically set automatically by n8n and should work out-of-the-box on most standard n8n setups. An n8n automation workflow template by Lucas Peyrin.
