n8n AI YouTube Analytics Agent: Comment Analyzer & Insights Reporter

This n8n workflow acts as an AI-powered agent to analyze YouTube video comments and generate insights, which are then reported via email and stored in a Google Sheet. It's designed to automate the process of understanding audience sentiment and extracting key information from YouTube comment sections.

What it does

This workflow automates the following steps:

Triggers on Google Sheet Update: The workflow is activated whenever a new row is added or an existing row is updated in a specified Google Sheet. This sheet is expected to contain YouTube video IDs or URLs.
Fetches YouTube Comments: For each entry from the Google Sheet, it retrieves comments from the corresponding YouTube video.
Limits Comment Processing: To prevent overwhelming the AI model and manage costs, it processes a limited number of comments per video.
Analyzes Comments with AI: The collected comments are fed into an AI Agent (powered by an OpenAI Chat Model) which is configured to analyze the comments. The AI agent likely identifies themes, sentiment, common questions, or other relevant insights.
Formats AI Output: The raw output from the AI agent is processed and formatted into a more readable structure.
Stores Insights in Google Sheet: The generated insights are then appended as a new row to a designated Google Sheet, creating a historical record of the analysis.
Reports Insights via Email: The workflow sends an email containing the AI-generated insights, likely to a predefined recipient, ensuring key stakeholders are informed.

Prerequisites/Requirements

To use this workflow, you will need:

n8n Instance: A running n8n instance (cloud or self-hosted).
Google Account: With access to Google Sheets.
- Google Sheets Credential: Configured in n8n for both the Trigger and the Google Sheets node.
YouTube API Key: Configured in n8n for the YouTube node to fetch comments.
- Google OAuth2 Credential: For YouTube API access.
OpenAI API Key: For the AI Agent and OpenAI Chat Model nodes.
- OpenAI Credential: Configured in n8n.
Gmail Account: To send email reports.

- Choose the trigger event (e.g., "On Update" or "On New Row").
Configure YouTube Node:
- Ensure the YouTube node is configured to retrieve comments based on the video ID provided by the Google Sheets Trigger.
Configure Limit Node: Adjust the "Limit" value in the Limit node if you want to process more or fewer comments per video.
Configure AI Agent and OpenAI Chat Model:
- Review the AI Agent and OpenAI Chat Model configurations. You may need to adjust the prompt or model parameters within the AI Agent to fine-tune the type of insights you want to extract from the comments.
Configure Edit Fields (Set) Node:
- Ensure this node correctly extracts and formats the relevant AI-generated insights for storage and email.
Configure Google Sheets (Output) Node:
- Specify the Spreadsheet ID and Sheet Name of the Google Sheet where the AI-generated insights will be stored.
- Map the data fields from the Edit Fields node to the appropriate columns in your output sheet.
Configure Gmail Node:
- Set the recipient email address, subject, and body of the email report. Use expressions to include the AI-generated insights in the email content.
Activate the Workflow: Once all configurations are complete, activate the workflow. It will now automatically run when changes occur in your input Google Sheet.

🎓 How to transform unstructured email data into structured format with AI agent

This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From – sender’s email address To – recipient’s email address Subject – email subject line Summary – short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits ✅ Full Automation: Eliminates manual reading and data entry from incoming emails. ✅ Multi-Source Integration: Handles data from different email providers seamlessly. ✅ AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. ✅ Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. ✅ Time Efficiency: Processes emails in real time, improving productivity and response speed. *✅ Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?

Automated YouTube video uploads with 12h interval scheduling in JST

This workflow automates a batch upload of multiple videos to YouTube, spacing each upload 12 hours apart in Japan Standard Time (UTC+9) and automatically adding them to a playlist. ⚙️ Workflow Logic Manual Trigger — Starts the workflow manually. List Video Files — Uses a shell command to find all .mp4 files under the specified directory (/opt/downloads/单词卡/A1-A2). Sort and Generate Items — Sorts videos by day number (dayXX) extracted from filenames and assigns a sequential order value. Calculate Publish Schedule (+12h Interval) — Computes the next rounded JST hour plus a configurable buffer (default 30 min). Staggers each video’s scheduled time by order × 12 hours. Converts JST back to UTC for YouTube’s publishAt field. Split in Batches (1 per video) — Iterates over each video item. Read Video File — Loads the corresponding video from disk. Upload to YouTube (Scheduled) — Uploads the video privately with the computed publishAtUtc. Add to Playlist — Adds the newly uploaded video to the target playlist. 🕒 Highlights Timezone-safe: Pure UTC ↔ JST conversion avoids double-offset errors. Sequential scheduling: Ensures each upload is 12 hours apart to prevent clustering. Customizable: Change SPANHOURS, BUFFERMIN, or directory paths easily. Retry-ready: Each upload and playlist step has retry logic to handle transient errors. 💡 Typical Use Cases Multi-part educational video series (e.g., A1–A2 English learning). Regular content release cadence without manual scheduling. Automated YouTube publishing pipelines for pre-produced content. --- Author: Zane Category: Automation / YouTube / Scheduler Timezone: JST (UTC+09:00)
