Gemini AI Auto-Publish Web Articles to X, LinkedIn, Reddit

Turn any web article into ready-to-post social updates—automatically (with AI-written copy + a live screenshot)

This n8n automation template converts a webpage URL into a set of platform-specific posts powered by AI (Gemini AI). It generates the social text for your audiences and captures a live screenshot of the page so your content can be shared consistently across X, LinkedIn, and Reddit—without manual drafting.

What this workflow does

• Takes a web article, blog post, or news link (the default example is configured for n8n templates—swap the URL to share anything).
• Uses an AI agent (LangChain agent) to produce tailored post content for each platform.
• Captures a live screenshot of the webpage to use as the post image.
• Publishes to social platforms, including Reddit and X/LinkedIn posting flows.
• Includes community nodes that work only on self-hosted n8n, so posting integrations may require a self-hosted setup.

Use cases

• Content curators sharing daily industry articles with consistent messaging and visuals.
• Social media managers keeping feeds active by turning links into ready-to-publish posts.
• SaaS operators promoting product updates, tutorials, and announcements from your blog.
• Community builders distributing relevant news and resources to your audiences, fast.
