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

1. Google Sheets → Profile URLs
   Add LinkedIn profile URLs into a Google Sheet tab — this is your watchlist.

2. Apify Scraper → Posts
   Fetches up to 10 posts per profile within the past 7 days.

3. Clean & Format
   Code nodes strip out clutter (hashtags, broken links, escapes).

4. OpenAI Summarizer
   AI rewrites posts into concise bullets and trims the digest under 500 words.

5. Slack Delivery
   Digest posts directly in Slack every Sunday morning, with original links attached as thread replies.
