n8n Workflow: TechCrunch RSS to Gemini Multi-Angle Carousels

Turn TechCrunch RSS into Multi-Angle LinkedIn & Instagram carousels—automatically

This n8n workflow monitors the TechCrunch RSS feed every minute, uses Google Gemini to generate three distinct LinkedIn content angles, then uses PostNitro to create and schedule LinkedIn document posts and Instagram carousel draft posts—complete with Gmail notifications for success or failure.

What this workflow does

• Polls TechCrunch RSS every minute to detect new articles.
• For each new article, sends the title, snippet, and URL to Google Gemini (PaLM) to produce three content angles as structured JSON (audience, angle, and hook).
• Splits the three angles into individual items and limits how many angles are processed per run.
• For each angle, calls PostNitro AI to generate a carousel design from the article URL.
• Creates two PostNitro scheduled drafts per angle:
  • LinkedIn document post
  • Instagram carousel post
• Schedules both drafts for one day later, using the angle’s hook as caption text.
• Emails Gmail confirmations with draft statuses and schedule times for the LinkedIn + Instagram results.
• If carousel generation fails for an angle, sends a Gmail alert including the error, article URL, and attempted angle.

Use cases

• For SaaS operators who want a consistent content pipeline from TechCrunch updates without manual ideation.
• For automation engineers building an RSS → AI angles → scheduled social drafts workflow in n8n.
• For founders who want multiple perspectives (three hooks) on the same news item across LinkedIn and Instagram.

Technical details

• n8n nodes/tooling: gmail, limit, merge, split out, sticky note, and n8n-nodes-langchainagent.
• AI generation: Google Gemini (PaLM) via the LangChain agent credential.
• Carousel creation & scheduling: PostNitro using configured brandId, presetId, templateId, and selected LinkedIn/Instagram account IDs.
• Notifications: Gmail OAuth2 with recipient email set in the Gmail node.

Setup checklist

• Add Google Gemini (PaLM) API credential for the LangChain agent.
• Add PostNitro API credential and set the required IDs for both platforms.
• Add Gmail OAuth2 credential and configure the recipient email address.
