n8n Workflow: RSS to LinkedIn & Instagram Carousels w/ Gemini

Turn TechCrunch RSS into LinkedIn + Instagram carousel drafts with Gemini (automatically)

This n8n workflow watches the TechCrunch RSS feed, uses Google Gemini to generate three audience-specific content angles per article, then creates PostNitro AI carousel designs and schedules LinkedIn document posts and Instagram carousel posts—with Gmail notifications for both successes and failures.

What this workflow does

• Monitors TechCrunch RSS by polling the feed every minute for newly published articles.
• Generates three content angles per article using Google Gemini. The workflow sends the article title, snippet, and URL to Gemini and requests hooks as structured JSON.
• Splits and limits processing: the three JSON angles are split into individual items, with a limit applied so only a controlled number of angles are handled per execution.
• Creates carousel design drafts: for each angle, PostNitro AI generates a carousel design using the article URL.
• Schedules platform-ready drafts in PostNitro:
  • one LinkedIn document post
  • one Instagram carousel post
  Both are scheduled for one day later, using the angle hook as the caption.
• Emails Gmail results: if both drafts are created, it sends a confirmation email with angle details and scheduled statuses; if generation fails, it emails an error report including the article link and failed angle.

Use cases

• For SaaS operators who want daily, consistent thought-leadership posts derived from TechCrunch.
• For automation engineers building a repeatable RSS → AI copy → social draft pipeline.
• For teams that want audience-specific angles and matching carousel assets without manual design work.

Technical details

• Google Gemini (PaLM) API credential for generating three structured JSON angles.
• PostNitro AI scheduled-post creation for both LinkedIn and Instagram (brandId/presetId/templateId + target account IDs required).
• Gmail OAuth2 for success and failure notifications (article link + angle reporting).
• n8n nodes include gmail, limit, merge, split out, and a sticky note, plus n8nn8n-nodes-langchainagent for the AI step.
