This n8n template demonstrates how to leverage AI to analyze trending short-form video content and automatically generate original, high-engagement video scripts inspired by proven viral formats.

Use cases are many: Create consistent content calendars for beauty salons and aestheticians, maintain a steady stream of reels without creative burnout, or study viral patterns to understand what drives engagement across Instagram's trending hashtags!

Good to know

  • The workflow scrapes real trending reels from Instagram based on your chosen hashtag, ensuring you're always learning from current viral patterns
  • Video transcription happens automatically, extracting the core messaging and pacing strategies from successful content
  • Generated scripts use proven engagement structures—hook, value delivery, and call-to-action timing—without copying original content
  • All data is organized in Google Sheets for easy review, editing, and tracking of script performance
  • The AI model intelligently mirrors the emotional tone and narrative structure while creating entirely new storylines

How it works

  • A form trigger collects your hashtag and desired number of reels to analyze
  • The Apify API scrapes trending Instagram reels matching your hashtag, filtering for high engagement (1000+ likes from the last 7 days)
  • Filtered reels are added to your Google Sheet with metadata: captions, engagement metrics, video links, and music information
  • Each reel is automatically transcribed using video-to-text technology, capturing the exact dialogue and timing
  • The AI Agent analyzes each transcript to understand its underlying structure—pacing, tone, curiosity hooks, and CTA placement
  • Using this analysis, Claude generates a completely original script that follows the same proven engagement formula but with a fresh topic or angle
  • Generated scripts are saved back to your Google Sheet alongside the source materials for comparison and refinement
  • A summary email is sent confirming the number of scripts created and ready for production

How to use

  • Start by entering a beauty or lifestyle hashtag (e.g., #aiautomation, #beautysalon, #haircare) and specify how many trending reels to analyze
  • Review the scraped content in your Google Sheet to understand what's currently resonating
  • Check the generated scripts and use them as jumping-off points for your own video production
  • Iterate on the process with different hashtags to discover emerging trends in your niche

Requirements

  • Apify account and API key for Instagram scraping (free tier available)
  • Google Sheets document set up to store reel data and generated scripts
  • OpenAI API key for the AI script generation
  • Gmail account for the completion notification (optional but recommended)

Customising this workflow

  • Adjust the engagement filter thresholds (currently 1000+ likes, 7 days old) to capture micro-trends or evergreen content
  • Modify the AI prompt in the "AI Agent" node to enforce specific brand voice, tone, or content guidelines
  • Add additional Google Sheet columns to track metrics like script-to-video conversion rates or audience response
  • Connect to additional distribution channels—automatically post scripts to team Slack, create video production briefs, or trigger video editing templates
  • Experiment with different video categories by creating multiple instances of this workflow for different hashtags or niches

Generate Viral Instagram Scripts by Analyzing Trending Reels with Apify and GPT-4

This n8n workflow automates the process of generating engaging Instagram Reel scripts by leveraging trending video data from Apify and the creative power of OpenAI's GPT-4. It streamlines content creation, helping you stay ahead of trends and produce viral-worthy content efficiently.

What it does

This workflow performs the following steps:

  1. Triggers on form submission: The workflow starts when an n8n form is submitted. This likely initiates the process with user-defined inputs for the content generation.
  2. Fetches trending Reel data (HTTP Request): It makes an HTTP request to an external API (likely Apify, given the directory name) to retrieve data on trending Instagram Reels.
  3. Filters out empty results: An "If" node checks if the API response contains valid data. If the response is empty, it sends an email notification.
  4. Loops over trending Reels: If data is found, a "Loop Over Items (Split in Batches)" node processes each trending Reel individually.
  5. Analyzes and generates script with AI (AI Agent & OpenAI Chat Model): For each Reel, an "AI Agent" node, powered by an "OpenAI Chat Model" (likely GPT-4), analyzes the trending content and generates a new Instagram Reel script based on the insights.
  6. Summarizes generated scripts: A "Summarize" node aggregates the generated scripts or key information from them.
  7. Stores scripts in Google Sheets: The summarized or generated scripts are then written to a Google Sheet for storage and further use.
  8. Sends email notification (Gmail): An email is sent with the generated scripts or a summary of the process.
  9. Includes a delay (Wait): A "Wait" node introduces a pause in the workflow, potentially to manage API rate limits or allow time for external processes.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n instance: A running n8n instance to host and execute the workflow.
  • Google Sheets Account: Configured credentials for Google Sheets to store the generated scripts.
  • Apify Account (or similar API): Access to an API that provides trending Instagram Reels data (configured for the HTTP Request node).
  • OpenAI API Key: Configured credentials for OpenAI (specifically for the GPT-4 chat model) to power the AI Agent.
  • Gmail Account: Configured credentials for Gmail to send email notifications.

Setup/Usage

  1. Import the workflow: Download the JSON provided and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Google Sheets credentials.
    • Set up your OpenAI credentials with access to GPT-4.
    • Set up your Gmail credentials.
  3. Configure HTTP Request Node: Update the "HTTP Request" node with the correct API endpoint and authentication details for your trending Reels data source (e.g., Apify).
  4. Configure n8n Form Trigger: Customize the form fields in the "On form submission" trigger to gather any necessary input for your script generation.
  5. Configure AI Agent: Review and adjust the prompt in the "AI Agent" node to guide GPT-4 on how to analyze the trending Reels and generate scripts according to your specific requirements (e.g., tone, length, call to action).
  6. Configure Google Sheets Node: Specify the Spreadsheet ID, Sheet Name, and the columns where you want to store the generated scripts.
  7. Configure Gmail Node: Update the recipient email address, subject, and body for the notification emails.
  8. Activate the workflow: Once configured, activate the workflow. You can then trigger it by submitting the n8n form.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
