Prompt Enhancer Pro

Right-click any selected text and process it via your own AI webhooks. Configure custom automation slots with secure local storage.

Prompt Enhancer Pro — AI Text Automation via Right-Click Select any text on any webpage, right-click, and instantly trigger your own AI-powered automation. The original text is replaced automatically with the AI-enhanced result — no tab switching, no copy-pasting, no workflow interruptions. Prompt Enhancer Pro connects your browser directly to your own AI backend via webhooks. You define the automation. You choose the AI model. You control your data. Whether you are a content writer, translator, developer, digital marketer, or support professional, Prompt Enhancer Pro removes the friction between you and your AI tools — and puts them exactly where your text already lives. Stop the copy-paste loop. Select text, right-click, done. ➤ HOW IT WORKS ① Select any text on any webpage — inside input fields, textareas, rich text editors, social media composers, CMS platforms, email clients, or anywhere else text appears. ② Right-click to open the browser's native context menu. ③ Hover over "✦ Prompt Enhancer" to reveal your list of custom AI actions. ④ Click any action — the extension sends your selected text to your configured n8n webhook. ⑤ Your AI backend processes the text using the model and system prompt you defined. ⑥ The selected text is automatically replaced in place with the AI output. That's the entire workflow. No new tabs. No copy and paste. No disruption to your focus. ➤ KEY FEATURES • RIGHT-CLICK CONTEXT MENU INTEGRATION All your AI automations appear directly in the browser's native right-click menu. Only actions you have enabled are shown — keeping the menu focused and clutter-free. The moment you disable an action in the extension, it disappears from the menu automatically. • UP TO 8 FULLY CUSTOMIZABLE ACTIONS Create up to 8 independent automation actions. Each action has its own display name, its own webhook URL, and its own n8n workflow behind it. Use one for grammar fixing, another for English translation, another for SEO rewriting, another for tone adjustment — the configuration is entirely yours to define and change at any time. • INSTANT IN-PLACE TEXT REPLACEMENT The selected text is replaced automatically with the AI-transformed output, right where your cursor is. Works across standard HTML input fields, textarea elements, contentEditable divs, and rich text editors including Google Docs, WordPress Gutenberg, and others. On platforms with strict content security policies, the enhanced text is automatically copied to your clipboard and a paste prompt is shown. • BRING YOUR OWN AI BACKEND — n8n POWERED Prompt Enhancer Pro is fully backend-agnostic. It sends your selected text to any HTTP POST webhook endpoint you configure. The recommended and supported backend is n8n — a powerful, free, open-source workflow automation platform. With n8n, you can connect GPT-4o, Claude 3.5, Gemini 1.5, Mistral, LLaMA, or any other AI model or API in minutes. You own the infrastructure, the AI model selection, the system prompt logic, and most importantly, your data never passes through any third-party service unless your own workflow calls one. • UNLIMITED AUTOMATION TYPES VIA n8n Because the backend is a fully programmable n8n workflow, you are not limited to simple text enhancement. You can build automations that rewrite text in any language, translate between any two languages, correct grammar and spelling in multilingual content, produce SEO-optimized rewrites of raw content, generate engaging headlines and titles from body text, convert rough notes into structured professional reports, summarize lengthy paragraphs into concise key points, adjust writing tone from casual to formal or vice versa, format content for specific platforms such as LinkedIn posts, Twitter threads, or email subject lines, classify or label incoming text, extract key entities or data points from unstructured text, connect to a database and look up context before responding, chain multiple AI models together in a single workflow, and add any custom conditional logic before or after AI processing. If n8n can execute it, this extension can trigger it from any webpage in Chrome. • WEBHOOK SECURITY — PASSWORD-PROTECTED HIDDEN URLs Webhook URLs grant access to your AI backend — they should be treated as credentials. Prompt Enhancer Pro protects all webhook URLs behind a local security password. When you open the extension, no webhook URL is ever shown on screen. To view or edit any webhook URL, you must first enter the correct password. The default password is "admin" and the extension prompts you to change it immediately after setup. The security password itself is stored in Chrome's local storage and is never transmitted anywhere. • ENABLE / DISABLE ACTIONS INSTANTLY Toggle any action on or off with a single switch inside the popup. Disabled actions are removed from the right-click menu and send no webhook requests. Re-enable them instantly at any time. This is useful for managing seasonal workflows, testing new automations alongside live ones, or temporarily removing actions you no longer need without deleting their configuration. • LIVE RIGHT-CLICK MENU PREVIEW The extension popup displays a real-time visual preview of exactly how your right-click context menu will appear in the browser. As you add actions, change their names, enable them, or disable them, the preview updates instantly — so you always know exactly what you will see before you right-click on a webpage. • WORKS ON ALL WEBSITES Works on virtually every website you visit in Chrome — including email clients, document editors, social media platforms, CMS tools, and project management applications. • SHADOW DOM TOAST NOTIFICATIONS All status notifications use an isolated Shadow DOM container that is completely separate from the host page's styling. This means the extension's notifications never cause visual glitches, layout shifts, or style conflicts on any website, regardless of how that website's CSS is structured. ➤ n8n BACKEND SETUP — STEP BY STEP Prompt Enhancer Pro requires an HTTP webhook endpoint that accepts a POST request containing the selected text and returns the transformed result. The following guide covers the complete setup using n8n. — — — STEP 1: GET n8n RUNNING Option A — n8n Cloud (recommended for beginners) Go to n8n.io and sign up for a free account. n8n Cloud gives you a hosted instance with no server configuration required. The free tier is sufficient for personal use. Option B — Self-hosted with Docker (recommended for teams and advanced users) Run the following command on your server or local machine: docker run -it --rm --name n8n -p 5678:5678 docker.n8n.io/n8nio/n8n Access your n8n instance at http://localhost:5678 Option C — Self-hosted on a VPS Install n8n on any Ubuntu or Debian server using npm: npm install n8n -g n8n start For production use, set up a reverse proxy with a domain name and HTTPS. — — — STEP 2: CREATE A NEW WORKFLOW In your n8n instance, click "New Workflow." Add a Webhook trigger node from the node panel. Set the HTTP method to POST. Note down the webhook URL that is generated — you will need it later. n8n provides both a test URL and a production URL. Use the test URL during development and the production URL when the workflow is live. — — — STEP 3: ADD AI PROCESSING NODES Connect any combination of the following n8n nodes after your Webhook trigger: • AI Agent node — for multi-step reasoning and tool use • Basic LLM Chain node — for straightforward text transformation • HTTP Request node — to call any external AI API directly • Code node — for custom JavaScript or Python preprocessing logic • If / Switch nodes — for conditional routing based on text content Connect your preferred AI model: • OpenAI (GPT-4o, GPT-4, GPT-3.5 Turbo) • Anthropic (Claude 3.5 Sonnet, Claude 3 Haiku) • Google (Gemini 1.5 Pro, Gemini 1.5 Flash) • Mistral, Ollama, HuggingFace, or any OpenAI-compatible endpoint Write a system prompt that defines exactly what the AI should do with the incoming text. The input text arrives in the webhook body as the "text" field. EXAMPLE SYSTEM PROMPTS: For professional text enhancement: "You are an expert writing assistant. Improve the clarity, tone, and professionalism of the input text. Keep the same language and meaning. Return only the improved text with no labels, no explanations, and no quotation marks." For Bengali to English translation: "Translate the provided text from Bengali into natural, professional English. Preserve the meaning and context. Return only the translated text." For grammar and spelling correction: "Identify and fix all grammar, spelling, punctuation, and sentence structure errors in the input text. Preserve the original language. Return only the corrected text." For paragraph summarization: "Summarize the input text into 2 to 3 concise, clear sentences that capture the main points. Return only the summary." For formal tone adjustment: "Rewrite the input text in a formal, professional tone suitable for business communication. Preserve the core meaning. Return only the rewritten text." For SEO content optimization: "Rewrite the input text to be more compelling, engaging, and optimized for web readers. Use clear headings in structure if appropriate, active voice, and concise language. Return only the rewritten content." — — — STEP 4: ADD A RESPOND TO WEBHOOK NODE Connect a Respond to Webhook node at the end of your workflow. Configure the response body to return the AI output in the format that Prompt Enhancer Pro expects: Recommended response format: ={{ JSON.stringify([{ "enhanced": $('AI Agent').item.json.output }]) }} Set the Content-Type header to application/json. The extension accepts the following response formats: • [{ "enhanced": "result" }] • [{ "output": "result" }] • [{ "response": "result" }] • [{ "text": "result" }] • { "enhanced": "result" } • "plain text string" — — — STEP 5: ACTIVATE THE WORKFLOW Click the Activate toggle in n8n to make the workflow live. Copy the Production Webhook URL from the Webhook trigger node settings. — — — STEP 6: CONFIGURE THE EXTENSION Open Prompt Enhancer Pro from your Chrome toolbar. Click "+ Add New Action." Enter a name for the action (e.g., "Enhance Text", "Translate to English"). Click Unlock and enter your security password (default: admin). Paste the Production Webhook URL. Enable the toggle. Click Save Action. Your action will now appear in the right-click menu on every webpage. ➤ REQUEST AND RESPONSE FORMAT REQUEST sent by the extension to your webhook: POST https://your-n8n-webhook-url Content-Type: application/json { "text": "the exact text that the user selected on the webpage" } RESPONSE expected from your backend: [{ "enhanced": "the processed and transformed text to replace the original" }] The extension automatically handles all standard response shapes and extracts the text content regardless of nesting level. ➤ PRIVACY AND SECURITY Your text is sent only to the webhook URLs you configure. The extension developer never receives any data, no analytics or telemetry is collected, and no third-party servers are involved unless your own n8n workflow explicitly calls them. All webhook URLs are stored locally on your device using Chrome's chrome.storage.local API and protected by your security password. URLs are never visible in the extension interface without authentication. Nothing is synced to any external server. The extension does not modify any page content except when you explicitly trigger an action. It does not inject advertisements, does not track browsing history or behavior, and does not communicate with any server outside the webhook URLs you personally configure. ➤ TECHNICAL SPECIFICATIONS • Manifest Version: V3 • Compatibility: Google Chrome 102 and above, Microsoft Edge 102 and above • Backend: Any HTTP POST webhook endpoint (n8n recommended) • Maximum Actions: 8 • Storage: chrome.storage.local (device-local, not synced) • Third-Party Libraries: None • Notification Layer: Isolated Shadow DOM ➤ COMING IN FUTURE VERSIONS • Transformation history log with before and after comparison • Export and import action configurations across devices • Site-specific actions — show different actions on different websites • Expanded to 16 action slots • Pre-built action templates for common tasks • Firefox browser support ➤ SUPPORT AND DOCUMENTATION Full documentation, n8n workflow templates, example system prompts, and troubleshooting guides are available in the project README on GitHub.
