Auto LinkedIn Engagement: AI Comments with GPT-4o & Phantombuster

This workflow automates LinkedIn engagement for B2B marketers, recruiters, and personal brand builders by posting short, relevant AI-generated comments on fresh industry content. It runs hourly: generating random AI/BPA search terms via GPT-4o, scraping recent posts with Phantombuster's LinkedIn Search Agent, selecting a random post, crafting a ≤150-char comment in your language, building a CSV, uploading to SharePoint, and launching the Auto-comment Agent with rotating session cookies to avoid detection and duplicates.

Key benefits include sparking genuine conversations without manual effort, staying under LinkedIn's daily limits (~120 comments/day via throttling), and logging commented posts to prevent repeats. It uses time-slice cookie rotation from SharePoint files for safety, customizable prompts for tone/length, and ENV variables for language/company tweaks.

Ideal use cases: Boost visibility on industry posts, nurture leads via thoughtful replies, or grow personal brands efficiently. Requires n8n 1.33+, Phantombuster Growth plan, OpenAI, and SharePoint. Setup involves credentials, file prep, and activation for hands-off operation.
