    • Build a WhatsApp Assistant with Memory, Google Suite, Multi-AI, Research, and Imaging

      The **WhatsApp Productivity Assistant with Memory and AI Imaging** is a comprehensive n8n workflow that transforms your WhatsApp into a powerful, multi-talented AI assistant. It's designed to handle a wide range of tasks by understanding user messages, analyzing images, and connecting to various external tools and services. The assistant can hold natural conversations, remember past interactions using a MongoDB vector store (RAG), and decide which tool is best suited for a user's request. Whether you need to check your schedule, research a topic, get the latest news, create an image, or even analyze a picture you send, this workflow orchestrates it all seamlessly through a single WhatsApp chat interface. The workflow is structured into several interconnected components: - **WhatsApp Trigger & Incoming Message Processing:** This is the entry point, starting when a message (text or image) is received via WhatsApp. A `Route Message by Type (Image/Text)` node then intelligently routes the message based on its content type. A `Typing...` node sends a typing indicator to the user for a better experience. If an image is received, it's downloaded, processed via an HTTP Request, and analyzed by the `Analyze image` node. The `Code1` node then standardizes both text and image analysis output into a single, unified input for the main AI agent. - **Core AI Agent:** This is the brain of the operation. The `AI Agent1` node receives the user's input, maintains short-term conversational memory using `Simple Memory`, and uses a powerful language model (`gpt-oss-120b2` or `gpt-oss-120b1`) to decide which tool or sub-agent to use. It orchestrates all the other agents and tools. - **Productivity Tools Agent:** This group of nodes connects the assistant to your personal productivity suite. It includes sub-agents and tools for managing `Google Calendar`, `Google Tasks`, and `Gmail`, allowing you to schedule events, manage to-dos, and read emails. It leverages a language model (`gpt-4.1-mini` or `gemini-2.5-flash`) for understanding and executing commands within these tools. - **Research Tool Agent:** This agent handles all research-related queries. It has access to multiple search tools (`Brave Web Search`, `Brave News Search`, `Wikipedia`, `Qwant`, and a custom `perplexcia` search) to find the most accurate and up-to-date information from the web. It uses a language model (`gpt-oss-120b` or `gpt-4.1-nanoChat Model1`) for reasoning. - **Long-term Memory Webhook:** A dedicated sub-workflow (`Webhook2`) that processes conversation history, extracts key information using `Extract Memory Info`, and stores it in a `MongoDB Atlas Vector Store` for long-term memory. This allows the AI agent to remember past preferences and facts. - **Image Generation Webhook:** A specialized sub-workflow (`Webhook3`) triggered when a user asks to create an image. It uses a dedicated `AI Agent` with `MongoDB Atlas Vector Store1` for contextual image prompt generation, `Clean Prompt Text1` to refine the prompt, an `HTTP Request` to an external image generation API (e.g., together.xyz), and then converts and sends the generated image back to the user via WhatsApp. --- ## Use Cases - **Personal Assistant:** Schedule appointments, create tasks, read recent emails, and manage your daily agenda directly from WhatsApp. - **Information Retrieval:** Ask any factual, news, or research-based question and get real-time answers from various web sources. - **Creative Content Generation:** Request the AI to generate images based on your descriptions for logos, artwork, or social media content. - **Smart Communication:** Engage in natural, contextual conversations with an AI that remembers past interactions. - **Image Analysis:** Send an image and ask the AI to describe its contents or answer questions about it. --- ## Pre-conditions Before importing and running this template, you will need: - **Self-hosted n8n Instance:** This template requires a self-hosted n8n instance as it uses webhooks that need public accessibility. - **WhatsApp Business Account:** A Meta Developer Account configured for WhatsApp Business Platform API access. - **MongoDB Atlas Account:** A MongoDB Atlas cluster with a database and collection set up for the vector store. - **Google Cloud Project:** Configured with API access for Google Calendar, Google Tasks, and Gmail. - **API Keys/Accounts for:** - **OpenWeatherMap:** For weather forecasts. - **Groq, OpenRouter, or Vercel AI Gateway:** For various Language Models (e.g., `gpt-oss-120b`, `gpt-5-nano`, `gpt-4o-mini`). - **Mistral Cloud:** For embedding models (e.g., `codestral-embed-2505`). - **Brave Search:** For web and news searches. - **Qwant API:** For structured search results. - **Together.xyz or similar Image Generation API:** For creating images. - **Perplexity API (or self-hosted)**

  5. n8n Documentation: Expert Chatbot with OpenAI RAG Pipeline

    # How It Works This template is a complete, hands-on tutorial for building a **RAG (Retrieval-Augmented Generation)** pipeline. In simple terms, you'll teach an AI to become an expert on a specific topic—in this case, the official **n8n documentation**—and then build a chatbot to ask it questions. Think of it like this: instead of a general-knowledge AI, you're building an **expert librarian**. --- ## Workflow Overview The workflow is split into two main parts: ### Part 1: Indexing the Knowledge (Building the Library) This is a **one-time process** you run manually. The workflow will: - Automatically scrape all pages of the **n8n documentation**. - Break them down into small, digestible chunks. - Use an AI model to create a numerical representation (an **embedding**) for each chunk. - Store these embeddings in **n8n's built-in Simple Vector Store**. > This is like a librarian reading every book and creating a hyper-detailed index card for every paragraph. > **Important:** This in-memory knowledge base is **temporary**. It will be erased if you restart your n8n instance. You'll need to run the indexing process again in that case. --- ### Part 2: The AI Agent (The Expert Librarian) This is the **chat interface**. When you ask a question: 1. The AI agent **doesn't guess** the answer. 2. It searches the knowledge base to find the most relevant "index cards" (chunks). 3. It feeds those chunks to a language model (**Gemini**) with strict instructions: > "Answer the user's question using ONLY this information." This ensures answers are accurate, factual, and grounded in your documents. --- ## Setup Steps > **Total setup time**: ~2 minutes > **Indexing time**: ~15-20 minutes This template uses **n8n's built-in tools**, so no external database is needed. ### 1. Configure OpenAI Credentials - You'll need an **OpenAI API key** (for GPT models). - In your n8n workflow: - Go to any of the three OpenAI nodes (e.g., `OpenAI Chat Model`). - Click the **Credential** dropdown → `+ Create New Credential`. - Enter your OpenAI API key and **save**. ### 2. Apply Credentials to All Nodes - Your new credential is now saved. - Go to the other two OpenAI nodes (e.g., `OpenAI Embeddings`) and select the newly created credential from the dropdown. ### 3. Build the Knowledge Base - Find the **Start Indexing** manual trigger node (top-left of the workflow). - Click the **Execute Workflow** button to start indexing. > **Be patient**: This takes 15-20 minutes to scrape and process the full documentation. > You only need to do this **once per n8n session**. ### 4. Chat With Your Expert Agent - After indexing completes, **activate** the entire workflow (toggle at the top). - Open the **RAG Chatbot** chat trigger node (bottom-left). - Copy its **Public URL**. - Open it in a new tab and ask questions about n8n! Example questions: - How does the IF node work? - What is a sub-workflow? --- ## Credits All credits go to **Lucas Peyrin** — [lucaspeyrin on n8n.io](https://n8n.io/creators/lucaspeyrin/)

    ### Generate **Product Requirements Document (PRD)** and **test scenarios** from input to PDF with OpenRouter and APIemplate.io This workflow generates a **Product Requirements Document (PRD)** and **test scenarios** from structured form inputs. It uses **OpenRouter LLMs (GP/Claude)** for natural language generation and **APIemplate.io** for PDF export. ## Who's it for This template is designed for **product managers, business analysts, QA teams, and startup founders** who need to quickly create **Product Requirement Documents (PRDs)** and **test cases** from structured inputs. ## How it works 1. A **Form Trigger** collects key product details (name, overview, audience, goals, requirements). 2. The **LLM Chain (OpenRouter GP/Claude)** generates a professional, structured **PRD in Markdown format**. 3. A second **LLM Chain** creates **test scenarios and Gherkin-style test cases** based on the PRD. 4. Data is cleaned and merged using a **Set node**. 5. The workflow sends the formatted document to **APIemplate.io** to generate a polished **PDF**. 6. Finally, the workflow returns the PDF via a **Form Completion node** for easy download. ## Requirements - OpenRouter API Key (or any LLM) - APIemplate.io account ## Use cases - Rapid PRD drafting for startups. - QA teams generating **test scenarios** automatically. - Standardized documentation workflows. ### Customize by editing prompts, PDF templates, or extending with integrations (Slack, Notion, Confluence). ### Need Help?

  12. **Build an Interactive AI Agent with Chat Interface and Multiple Tools**

    ## How it works This template is a complete, hands-on tutorial that lets you build and interact with your very first AI Agent. Think of an AI Agent as a standard AI chatbot with **superpowers**. The agent doesn't just talk; it can **use tools** to perform actions and find information in real-time. This workflow is designed to show you exactly how that works. 1. **The Chat Interface (Chat Trigger):** This is your window to the agent. It's a fully styled, public-facing chat window where you can have a conversation. 2. **The Brain (AI Agent Node):** This is the core of the operation. It takes your message, understands your intent, and intelligently decides which superpower (or tool) it needs to use to answer your request. The agent's personality and instructions are defined in its extensive system prompt. 3. **The Tools (Tool Nodes):** These are the agent's superpowers. We've included a variety of useful and fun tools to showcase its capabilities: - Get a random joke. - Search Wikipedia for a summary of any topic. - Calculate a future date. - Generate a secure password. - Calculate a monthly loan payment. - Fetch the latest articles from the n8n blog. 4. **The Memory (Memory Node):** This gives the agent a short-term memory, allowing it to remember the last few messages in your conversation for better context. When you send a message, the agent's brain analyzes it, picks the right tool for the job, executes it, and then formulates a helpful response based on the tool's output. ## Set up steps **Setup time: ~3 minutes** This template is nearly ready to go out of the box. You just need to provide the AI's brain. 1. **Configure Credentials:** This workflow requires an API key for an AI model. Make sure you have credentials set up in your n8n instance for either **Google AI (Gemini)** or **OpenAI**. 2. **Choose Your AI Brain (LLM):** - By default, the workflow uses the **Google Gemini** node. If you have Google AI credentials, you're all set! - If you prefer to use **OpenAI**, simply **disable the Gemini node** and **enable the OpenAI node**. You only need one active LLM node. Make sure it is connected to the Agent parent node. 3. **Explore the Tools:** Take a moment to look at the different tool nodes connected to the `Your First AI Agent` node. This is where the agent gets its abilities! You can add, remove, or modify these to create your own custom agent. 4. **Activate and Test!** - Activate the workflow. - Open the **public URL** for the `Example Chat Window` node (you can copy it from the nodes panel). - Start chatting! Try asking it things like: - Tell me a joke. - What is n8n? - Generate a 16-character password for me. - What are the latest posts on the n8n blog? - What is the monthly payment for a $300,000 loan at 5% interest over 30 years?

  13. Free AI Image Generator - n8n Automation Workflow with Gemini/ChatGPT

    ### This n8n template demonstrates how to use AI to generate custom images from scratch - fully automated, prompt-driven, and ready to deploy at scale. Use cases are many: You can use it for marketing visuals, character art, digital posters, storyboards, or even daily image generation for your personal purposes. ## How It Works - The flow is triggered by a chat message in n8n or via Telegram. The default image size is 1080 x 1920 pixels. To use a different size, update the values in the **“Fields - Set Values”** node before triggering the workflow. - The input is parsed into a clean, structured prompt using a multi-step transformation process. - Our AI Agent sends the final prompt to Google Gemini's image model for generation (you can also integrate with OpenAI or other chat models). - The raw image data created by the AI Agent will be run through a number of codes to make sure it's feasible for your preview if needed and downloading. - Then, we use an HTTP node to fetch the result so you can preview the image. - You can send it back to the chat message in n8n or Telegram, or save it locally to your disk. ## How To Use - Download the workflow package. - Import the package into your n8n interface. - Set up the credentials in the following nodes for tool access and usability: **Telegram Trigger**; **AI Agent - Create Image From Prompt**; **Telegram Response** or **Save Image To Disk** (based on your wish). - Activate the **Telegram Response** OR **Save Image To Disk** node to specify where you want to save your image later. - Open the chat interface (via n8n or Telegram). - Type your image prompt or detailed descriptions and send. - Wait for the process to run and finish in a few seconds. - Check the result in your desired saving location. ## Requirements - Google Gemini account with image generation access. - Telegram bot access and chat setup (optional). - Connection to local storage (optional). ## How To Customize - We're setting the default image size to 1080 x 1920 pixels and the default image model to flux. You can customize both of these values in the **“Fields - Set Values”** node. Supported image model options include: flux, kontext, turbo, and gptimage. - In the **“AI Agent - Create Image From Prompt”** node, you can also change the AI chat model. By default, it uses Google Gemini, but you can easily replace it with OpenAI ChatGPT, Microsoft AI Copilot, or any other compatible provider. ## Need Help?
