Automate LinkedIn Post Summaries to Slack with AI and Apify

Turn LinkedIn Noise Into Weekly Slack Insights 🚀

What if your team could skim the best of LinkedIn in 2 minutes instead of scrolling for hours?
This workflow transforms raw LinkedIn posts into a bite-sized Slack digest — summarized, grouped, and delivered automatically every week.

⚡ What It Does Scrapes Posts Automatically**: Pulls fresh posts from LinkedIn profiles you specify (via Apify). Summarizes with AI: Condenses each post into 2–3 bullets (≤15 words). Keeps It Lean: Digest capped at 500 words total. Organized by Author: See exactly who said what, without searching. Delivers to Slack: Neatly formatted digest drops in your channel on schedule, with post links in thread replies.

🛠 How It Works Google Sheets → Profile URLs
Add LinkedIn profile URLs into a Google Sheet tab — this is your watchlist.
