N8N Master - Workflow Assistant

n8n Master – Browser Extension for AI-Powered Workflow Automation in n8n

n8n Master is a powerful browser extension designed to dramatically extend the functionality of the n8n workflow editor. It integrates AI features, boosts productivity, and introduces a range of enhancements that make working with n8n more efficient, intelligent, and enjoyable.

View all your workflows and executions directly in the extension; no more searching for your workflows, opening nodes, or getting external links for your webhooks and forms. Connect the n8n API and copy trigger links in just a couple of clicks!

🔗 AI Provider Support
Connect any AI model via API from:
• OpenAI (ChatGPT, GPT-4, etc.)
• Anthropic (Claude 3 / Claude 4)
• OpenRouter (a proxy to multiple models like Mistral, Mixtral, Grok, etc.)
• Local LMs

Just add your preferred API key in the extension settings to unlock AI features.

🚀 Key Features
⚡ Context Menu Actions (AI-powered)
Accessible via right-click in input fields:

• Optimize Prompt – Improves selected prompt text for AI agents
• Generate Prompt – Generates prompts from plain-language descriptions
• Generate Code – Writes JavaScript code for CODE nodes based on instructions
• Generate JSON – Converts text descriptions into valid JSON structures
• Generate cURL – Creates a cURL request for HTTP Request nodes based on current settings
• Explain Code – AI-powered explanation of JavaScript code (entire blocks or selected parts)

🤖 Smart AI Assistant
Use natural language commands directly in the chat sidebar to:
• Generate entire workflows from plain-language tasks
e.g. “Create a Telegram bot with an AI agent”
• Analyze existing workflows
Ask: “What does this workflow do?”
• Explain selected nodes to understand individual components step-by-step

🧪 Webhook Output Templates
Inside Webhook nodes, a new Output Templates interface appears:

• Save current output payloads to local cache
• Select and reuse saved templates for testing
• Delete obsolete templates
• Use advanced search and replace across output contents

Ideal for safely testing different incoming parameters without needing external tools.

💎 Premium Features

🔐 Auto Save
Automatically saves your workflow after each change, protecting you from losing progress due to accidental tab closures or crashes.

🔐 Auto Pin HTTP
After a successful test of an HTTP Request node, the response is cached to prevent duplicate requests—ideal for paid APIs.

🔐 Auto Pin AI
Same behavior for AI responses—saving time, reducing API usage, and maintaining consistency.

🔐 Enable History (for self-hosted n8n)
If you use n8n without an Enterprise license, version history is not available by default.
This feature:
• Saves each version locally using the n8n API
• Displays the history in place of the default (disabled) history button

📚 Show Templates
Quick access to almost 300 ready-made templates, which can be copied and used directly in your workflows.

🔄 Node Selector
Adds a selector button to each node, letting you copy nodes with settings from your existing workflows—without opening them in a new tab.

🧠 AI Error Trigger
When a node test fails, the error message and node context (parameters + config) are automatically sent to AI, which responds with a probable cause and fix.

🗂 Local Projects
Activate folders in the sidebar to organize workflows into colored project folders. Move workflows between folders. Requires an n8n API key.

🧾 Local Variables
Redesigns the Variables link in the sidebar:

• Add your own frequently used data like Telegram ID, email, constants
• Copy-paste any item instantly
• Use Ctrl + Shift + V to access variables from any node

💬 Remember Dialog
Each workflow retains its own AI chat context. When switching between workflows, AI remembers the previous conversation related to that project.

🧪 Node Execution Select
In the Output editor, you can now select a specific past execution to use as test input—no need to copy from the Executions tab manually.

🎛 Custom AI Models & Context Settings
• Select any supported model from OpenAI, Anthropic, or OpenRouter
• Configure prompt structures, instructions, or context settings for each command
• Fine-tune generation behavior to your liking

📦 Import & Export Settings
Export your entire extension configuration and import it later or on another device — ideal for backup or team use.
