Daily AI News Digest with Perplexity Pro (GPT Format) & Gmail Delivery

This n8n workflow automates the creation and delivery of a daily AI news digest. It leverages Perplexity Pro for comprehensive news gathering and an AI agent (powered by OpenAI) to summarize and format the news into a concise, GPT-style digest, which is then delivered via Gmail.

What it does

  1. Triggers Daily: The workflow is scheduled to run once every day.
  2. Gathers AI News: It uses the Perplexity node to search for the latest news and updates related to Artificial Intelligence.
  3. Summarizes with AI Agent: An AI Agent node (configured with an OpenAI Chat Model and Simple Memory) processes the news articles from Perplexity.
    • It's prompted to act as an "AI News Reporter" and create a "Daily AI News Digest."
    • The digest is formatted in a "GPT style," focusing on key points and a concise summary.
  4. Delivers via Gmail: The final AI news digest, formatted by the AI Agent, is sent as an email using the Gmail node.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance (self-hosted or cloud).
  • Perplexity API Key: An API key for Perplexity Pro to gather news.
  • OpenAI API Key: An API key for OpenAI to power the AI Agent and Chat Model.
  • Gmail Account: A configured Gmail credential in n8n to send the digest emails.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Perplexity: Set up a new Perplexity credential using your API key.
    • OpenAI: Set up a new OpenAI credential using your API key.
    • Gmail: Set up a new Google OAuth2 credential for Gmail, ensuring it has permission to send emails.
  3. Configure Nodes:
    • Schedule Trigger (Node 839): By default, it's set to run daily. Adjust the schedule as needed (e.g., specific time, interval).
    • Perplexity (Node 1304): Ensure your Perplexity credential is selected. The query is pre-set to "latest AI news." You can modify this query to refine the news topics.
    • AI Agent (Node 1119):
      • Ensure your OpenAI credential is selected for the "OpenAI Chat Model" sub-node.
      • Review the "System Message" and "User Message" prompts to ensure they align with your desired digest style and content. The current prompt instructs the agent to act as an "AI News Reporter" and create a "Daily AI News Digest" in "GPT style."
    • Gmail (Node 356):
      • Select your Gmail credential.
      • To: Enter the recipient email address(es) for the digest.
      • Subject: Customize the email subject (e.g., "Daily AI News Digest - {{ $today }}").
      • Body: The email body will automatically use the output from the AI Agent node, which contains the formatted digest.
  4. Activate the Workflow: Once all credentials and configurations are set, activate the workflow. It will then run according to its schedule.

Track daily moods with AI analysis & reports using GPT-4o, Data Tables & Gmail

Track your daily mood in one tap and receive automated AI summaries of your emotional trends every week and month. Perfect for self-reflection, wellness tracking, or personal analytics. This workflow logs moods sent through a webhook (/mood) into Data Tables, analyzes them weekly and monthly with OpenAI (GPT-4o), and emails you clear summaries and actionable recommendations via Gmail. ⚙️ How It Works Webhook – Mood → Collects new entries (🙂, 😐, or 😩) plus an optional note. Set Mood Data → Adds date, hour, and note fields automatically. Insert Mood Row → Stores each record in a Data Table. Weekly Schedule (Sunday 20:00) → Aggregates the last 7 days and sends a summarized report. Monthly Schedule (Day 1 at 08:00) → Aggregates the last 30 days for a deeper AI analysis.

IT ops AI SlackBot workflow - chat with your knowledge base

Video Demo: Click here to see a video of this workflow in action. Summary Description: The "IT Department Q&A Workflow" is designed to streamline and automate the process of handling IT-related inquiries from employees through Slack. When an employee sends a direct message (DM) to the IT department's Slack channel, the workflow is triggered. The initial step involves the "Receive DMs" node, which listens for new messages. Upon receiving a message, the workflow verifies the webhook by responding to Slack's challenge request, ensuring that the communication channel is active and secure. Once the webhook is verified, the workflow checks if the message sender is a bot using the "Check if Bot" node. If the sender is identified as a bot, the workflow terminates the process to avoid unnecessary actions. If the sender is a human, the workflow sends an acknowledgment message back to the user, confirming that their query is being processed. This is achieved through the "Send Initial Message" node, which posts a simple message like "On it!" to the user's Slack channel. The core functionality of the workflow is powered by the "AI Agent" node, which utilizes the OpenAI GPT-4 model to interpret and respond to the user's query. This AI-driven node processes the text of the received message, generating an appropriate response based on the context and information available. To maintain conversation context, the "Window Buffer Memory" node stores the last five messages from each user, ensuring that the AI agent can provide coherent and contextually relevant answers. Additionally, the workflow includes a custom Knowledge Base (KB) tool (see that tool template here) that integrates with the AI agent, allowing it to search the company's internal KB for relevant information. After generating the response, the workflow cleans up the initial acknowledgment message using the "Delete Initial Message" node to keep the conversation thread clean. Finally, the generated response is sent back to the user via the "Send Message" node, providing them with the information or assistance they requested. This workflow effectively automates the IT support process, reducing response times and improving efficiency. To quickly deploy the Knowledge Ninja app in Slack, use the app manifest below and don't forget to replace the two sample urls: { "display_information": { "name": "Knowledge Ninja", "description": "IT Department Q&A Workflow", "background_color": "005e5e" }, "features": { "bot_user": { "display_name": "IT Ops AI SlackBot Workflow", "always_online": true } }, "oauth_config": { "redirect_urls": [ "Replace everything inside the double quotes with your slack redirect oauth url, for example: https://n8n.domain.com/rest/oauth2-credential/callback" ], "scopes": { "user": [ "search:read" ], "bot": [ "chat:write", "chat:write.customize", "groups:history", "groups:read", "groups:write", "groups:write.invites", "groups:write.topic", "im:history", "im:read", "im:write", "mpim:history", "mpim:read", "mpim:write", "mpim:write.topic", "usergroups:read", "usergroups:write", "users:write", "channels:history" ] } }, "settings": { "event_subscriptions": { "request_url": "Replace everything inside the double quotes with your workflow webhook url, for example: https://n8n.domain.com/webhook/99db3e73-57d8-4107-ab02-5b7e713894ad", "bot_events": [ "message.im" ] }, "orgdeployenabled": false, "socketmodeenabled": false, "tokenrotationenabled": false } }
