Automate LinkedIn Comment Replies with GPT-3.5 & Track in Sheets
Automates replies to LinkedIn post comments using GPT-3.5, filters new ones, posts responses, and logs to Google Sheets for tracking.
This n8n workflow automates LinkedIn community engagement by monitoring comments on a specific post every 10 minutes via Schedule Trigger. It fetches latest comments using LinkedIn API, filters new ones by comparing timestamps from Google Sheets, generates professional AI replies with OpenAI GPT-3.5 Turbo, posts them back to LinkedIn, and logs all data for analytics.
The process ensures no duplicates, maintains authentic branding, and handles replies concisely (2-3 sentences). Key nodes include filtering logic, structured AI prompting, API posting, and sheet appending.
Benefits include time savings on manual replies, timely professional responses, scalable engagement without effort, and audit-ready logs. Ideal for marketers, brands, or professionals boosting LinkedIn presence.
Use cases: Community managers tracking post interactions, solopreneurs scaling outreach, agencies handling client social media, or sales teams nurturing leads via comments.
