🧠 How it works

This workflow enables automatic translation in Slack using n8n and OpenAI.
When a user types /trans followed by text, n8n detects the language and replies with the translated version via Slack.

⚙️ Features

Detects the input language automatically
Translates between Japanese ↔ English using GPT-4o-mini (temperature 0.2 for stability)
Sends a quick “Translating...” acknowledgement to avoid Slack’s 3s timeout
Posts the translated text back to Slack (public or private selectable)
Supports overrides like en: こんにちは or ja: hello

💡 Perfect for

Global teams communicating in Japanese and English
Developers learning how to connect Slack + OpenAI + n8n

🧩 Notes

Create an AI Telegram bot using Google Drive, Qdrant, and OpenAI GPT-4.1

### How it works This workflow creates an intelligent Telegram bot with a knowledge base powered by Qdrant vector database. The bot automatically processes documents uploaded to Google Drive, stores them as embeddings, and uses this knowledge to answer questions in Telegram. It consists of two independent flows: **document processing** (Google Drive → Qdrant) and **chat interaction** (Telegram → AI Agent → Telegram). ### Step-by-step **Document Processing Flow:** * **New File Trigger:** The workflow starts when the **New File Trigger** node detects a new file created in the specified Google Drive folder (polling every 15 minutes). * **Download File:** The **Download File** (Google Drive) node downloads the detected file from Google Drive. * **Text Splitting:** The **Split Text into Chunks** node splits the document text into chunks of 3000 characters with 300 character overlap for optimal embedding. * **Load Document Data:** The **Load Document Data** node processes the binary file data and prepares it for vectorization. * **OpenAI Embeddings:** The **OpenAI Embeddings** node generates vector embeddings for each text chunk. * **Insert into Qdrant:** The **Insert into Qdrant** node stores the embeddings in the Qdrant vector database collection. * **Move to Processed Folder:** After successful processing, the **Move to Processed Folder** (Google Drive) node moves the file to a "Qdrant Ready" folder to keep files organized. **Telegram Chat Flow:** * **Telegram Message Trigger:** The **Telegram Message Trigger** node receives new messages from the Telegram bot. * **Filter Authorized User:** The **Filter Authorized User** node checks if the message is from an authorized chat ID (26899549) to restrict bot access. * **AI Agent Processing:** The **AI Agent** receives the user's message text and processes it using the fine-tuned GPT-4.1 model with access to the Qdrant knowledge base tool. * **Qdrant Knowledge Base:** The **Qdrant Knowledge Base** node retrieves relevant information from the vector database to provide context for the AI agent's responses. * **Conversation Memory:** The **Conversation Memory** node maintains conversation history per chat ID, allowing the bot to remember context. * **Send Response to Telegram:** The **Send Response to Telegram** node sends the AI-generated response back to the user in Telegram. ### Set up steps Estimated set up time: 15 minutes 1. **Google Drive Setup:** * Add your Google Drive OAuth2 credentials to the **New File Trigger**, **Download File**, and **Move to Processed Folder** nodes. * Create two folders in your Google Drive: one for incoming files and one for processed files. * Copy the folder IDs from the URLs and update them in the **New File Trigger** (folderToWatch) and **Move to Processed Folder** (folderId) nodes. 2. **Qdrant Setup:** * Add your Qdrant API credentials to the **Insert into Qdrant** and **Qdrant Knowledge Base** nodes. * Create a collection in your Qdrant instance (e.g., "Test-youtube-adept-ecom"). * Update the collection name in both Qdrant nodes. 3. **OpenAI Setup:** * Add your OpenAI API credentials to the **OpenAI Chat Model** and **OpenAI Embeddings** nodes. * (Optional) Replace the fine-tuned model ID in **OpenAI Chat Model** with your own model or use a standard model like `gpt-4-turbo`. 4. **Telegram Setup:** * Create a Telegram bot via [@BotFather](https://t.me/botfather) and obtain the bot token. * Add your Telegram bot credentials to the **Telegram Message Trigger** and **Send Response to Telegram** nodes. * Update the authorized chat ID in the **Filter Authorized User** node (replace `26899549` with your Telegram user ID). 5. **Customize System Prompt (Optional):** * Modify the system message in the **AI Agent** node to customize your bot's personality and behavior. * The current prompt is configured for an n8n automation expert creating social media content. 6. **Activate the Workflow:** * Toggle "Active" in the top-right to enable both the Google Drive trigger and Telegram trigger. * Upload a document to your Google Drive folder to test the document processing flow. * Send a message to your Telegram bot to test the chat interaction flow.

Control AI agent tool access with Port RBAC and Slack mentions

## RBAC for AI agents with n8n and Port This workflow implements role-based access control for AI agent tools using Port as the single source of truth for permissions. Different users get access to different tools based on their roles, without needing a separate permission database. For example, developers might have access to PagerDuty and AWS S3, while support staff only gets Wikipedia and a calculator. The workflow checks each user's permissions in Port before letting the agent use any tools. For the full guide with blueprint setup and detailed configuration, see [RBAC for AI Agents with n8n and Port](https://docs.port.io/guides/all/implement-rbac-for-ai-agents-with-n8n-and-port/) in the Port documentation. ## How it works The n8n workflow orchestrates the following steps: - Slack trigger — Listens for @mentions and extracts the user ID from the message. - Get user profile — Fetches the user's Slack profile to get their email address. - Port authentication — Requests an access token from the Port API using client credentials. - Permission lookup — Queries Port for the user entity (by email) and reads their allowed_tools array. - Unknown user check — If the user doesn't exist in Port, sends an error message and stops. - Permission filtering — The "Check permissions" node compares each connected tool against allowed_tools and replaces unauthorized ones with a stub that returns "You are not authorized to use this tool." - AI agent — Runs with only permitted tools, using GPT-4 and chat memory. - Response — Posts the agent output back to the Slack channel. ## Setup - [ ] Connect your Slack account and set the channel ID in the trigger node - [ ] Add your OpenAI API key - [ ] Register for free on [Port.io](https://www.port.io) - [ ] Create the rbacUser blueprint in Port (see [full guide](https://docs.port.io/guides/all/implement-rbac-for-ai-agents-with-n8n-and-port/) for blueprint setup) - [ ] Add user entities using email as the identifier - [ ] Replace YOUR_PORT_CLIENT_ID and YOUR_PORT_CLIENT_SECRET in the "Get Port access token" node - [ ] Connect credentials for any tools you want to use (PagerDuty, AWS, etc.) - [ ] Update the channel ID in the Slack nodes - [ ] Invite the bot to your Slack channel - [ ] You should be good to go! ## Prerequisites - You have a Port account and have completed the onboarding process. - You have a working n8n instance (self-hosted) with LangChain nodes available. - Slack workspace with bot permissions to receive mentions and post messages. - OpenAI API key for the LangChain agent. - Port client ID and secret for API authentication. - (Optional) PagerDuty, AWS, or other service credentials for tools you want to control. ⚠️ This template is intended for Self-Hosted instances only.

Create AI FAQ articles from Slack threads into Notion and Zendesk

# Create FAQ articles from Slack threads to Notion and Zendesk This workflow helps you capture "tribal knowledge" shared in Slack conversations and automatically converts it into structured documentation. By simply adding a specific reaction (default: 📚) to a message, the workflow aggregates the thread, uses AI to summarize it into a Q&A format, and publishes it to your knowledge base (Notion and Zendesk). ## Who is this for? - **Customer Support Teams** who want to turn internal troubleshooting discussions into public help articles. - **Knowledge Managers** looking to reduce the friction of documentation. - **Development Teams** wanting to archive technical decisions made in Slack threads. ## What it does 1. **Trigger:** Watches for a specific emoji reaction (📚 `:book:`) on a Slack message. 2. **Data Collection:** Fetches the parent message and all replies in the thread to get the full context. 3. **AI Processing:** Uses **OpenAI** to analyze the conversation, summarize the solution, and format it into a clear Question & Answer structure. 4. **Publishing:** - Creates a new page in a **Notion** database with tags and summaries. - (Optional) Drafts a new article in **Zendesk**. 5. **Notification:** Replies to the original Slack thread with links to the newly created documentation. ## Requirements - **n8n** (Self-hosted or Cloud) - **Slack** workspace (with an App installed that has permissions to read channels and reactions). - **OpenAI** API Key. - **Notion** account with an Integration Token. - **Zendesk** account (optional, can be removed if not needed). ## How to set up 1. **Configure Credentials:** Set up authentication for Slack, OpenAI, Notion, and Zendesk in n8n. 2. **Setup Notion:** Create a database in Notion with the following properties: - `Name` (Title) - `Summary` (Text/Rich Text) - `Tags` (Multi-select) - `Source` (URL) - `Channel` (Select or Text) 3. **Update Configuration Node:** Open the **Workflow Configuration1** node (Set node) and replace the placeholder values: - `slackWorkspaceId`: Your Slack Workspace ID (e.g., T01234567). - `notionDatabaseId`: The ID of your Notion database. - `zendeskSectionId`: (Optional) The ID of the section where articles should be created. 4. **Slack App Scopes:** Ensure your Slack App has the following scopes: `reactions:read`, `channels:history`, `groups:history`, `chat:write`. ## How to customize - **Change the Trigger:** If you prefer a different emoji (e.g., 📝 or 💡), update the "Right Value" in the **IF - :book: Reaction Check** node. - **Modify the Prompt:** Edit the **OpenAI** node to change how the AI formats the answer (e.g., ask it to be more technical or more casual). - **Remove Zendesk:** If you don't use Zendesk, simply delete the **Zendesk** node and remove the reference to it in the final **Slack - Notify Completion** node.
