n8n YouTube Lead Generation Workflow

This n8n workflow is designed to extract, enrich, and manage potential leads from YouTube comments using AI. It leverages Apify for data extraction and Gemini AI (via OpenRouter) for comment analysis and lead qualification, storing the enriched data in Google Sheets.

What it does

This workflow automates the following steps:

Trigger: The workflow can be manually executed or scheduled to run at predefined intervals.
Initial Data: A Sticky Note node provides initial context or data, likely for Apify's YouTube Comment Scraper.
YouTube Comment Scraping (via HTTP Request): It makes an HTTP request to Apify to initiate a YouTube comment scraping task. This step is configured to use an Apify API key and a specific Apify actor ID.
Wait for Apify Task (via HTTP Request): The workflow then polls Apify's API to check the status of the scraping task until it completes.
Fetch Apify Results (via HTTP Request): Once the scraping task is done, it fetches the results (the scraped YouTube comments) from Apify.
Prepare Comments for AI (Code): A Code node processes the raw comments, likely formatting them into a structured input suitable for the AI agent.
AI Agent for Lead Qualification: An AI Agent node (powered by LangChain) uses a conversational model (OpenRouter Chat Model, likely Gemini AI) and a simple memory to analyze the comments. It's designed to identify potential leads based on the content of the comments.
Store Enriched Leads (Google Sheets): Finally, the qualified leads and their enriched data are written to a Google Sheet.

Prerequisites/Requirements

To use this workflow, you will need:

n8n Instance: A running n8n instance.
Apify Account: An Apify account with an API key and access to a YouTube Comment Scraper actor.
OpenRouter Account: An OpenRouter account with an API key to access AI models like Gemini.
Google Account: A Google account for Google Sheets integration.
YouTube Video ID(s): The ID(s) of the YouTube video(s) from which you want to scrape comments.

Setup/Usage

Import the workflow: Download the JSON provided and import it into your n8n instance.
Configure Credentials:
- Apify: Set up an HTTP Request credential for Apify with your API key.
- OpenRouter: Set up an OpenRouter Chat Model credential with your API key.
- Google Sheets: Set up a Google Sheets credential (OAuth2 recommended) to grant n8n access to your Google Sheets.
Configure Apify HTTP Requests:
- Update the "HTTP Request" nodes related to Apify (scraping, checking status, fetching results) with your Apify API key and the correct Apify actor ID.
- Ensure the YouTube video ID(s) are passed correctly to the Apify scraping request, possibly via the "Sticky Note" or a preceding node.
Configure AI Agent:
- Ensure the "OpenRouter Chat Model" node is correctly configured with the desired AI model (e.g., Gemini) and any specific parameters.
- Review the prompt or instructions within the "AI Agent" node to ensure it aligns with your lead qualification criteria.
Configure Google Sheets:
- Specify the Spreadsheet ID and Sheet Name where you want to store the enriched lead data.
- Adjust the column mapping in the "Google Sheets" node to match the data output from the AI Agent.
Activate the Workflow:
- You can run the workflow manually using the "When clicking ‘Execute workflow’" trigger.
- Alternatively, configure the "Schedule Trigger" node to run the workflow at your desired intervals (e.g., daily, weekly).

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
