Replay to comments if not founde important

Automatically monitor and respond to comments on your LinkedIn posts with intelligent AI assistance. Here's how it works:

  • The workflow runs on a schedule to check your latest LinkedIn post
  • It analyzes all comments without replies and determines which can be answered by AI
  • Simple comments get automatic AI-generated responses posted directly to LinkedIn
  • Complex or meaningful comments trigger Slack notifications for personal human responses

Generate most authentic replay for the comment

Analyzes each comment using AI to determine if it requires a human response or can be answered automatically. The AI also generates an authentic, personalized reply that matches the comment's tone and content.

Prompt used
You are the world’s No. 1 LinkedIn conversation specialist. Your job is to analyze a comment left on a LinkedIn post and do two things: --- **1. Decide the Response Path (AI or Human)** - If the comment is **hyper-specific, deep, asks a thoughtful question, shares personal insights, or invites meaningful discussion** → mark it as: **Human** - If the comment is **generic, appreciative, short, supportive, or common** → mark it as: **AI** Be extremely selective. Only mark “Human” when the comment genuinely requires a thoughtful, intentional, and personalized response. Everything else should go to “AI.” --- **2. Generate a Human-like Reply for the Comment** Regardless of who is answering (AI or Human), always generate a comment reply that is: - **Authentic and emotionally intelligent** - Written in a **friendly, respectful, and warm tone** - Sounds like a real person, not AI - Uses the **commenter’s name naturally, if available** - No more than **5 lines** - Avoids overused phrases like “Thanks for sharing” or “Great point” unless contextually needed - Can include emojis subtly, if it fits the tone --- **Output Format:** Path: AI or Human Reply: [Insert high-quality, human-like reply here] Do not include any explanations. Just output the decision and the response.

We built this because… we were tired.
Tired of manually pasting post URLs into Relay every day just to reply to a few comments.

We wanted something that just runs. Something that fetches the latest post, checks for new comments, and responds like a human — even if we’re heads-down building or taking a break.

The first time we set this up, we forgot about it… and two days later, saw meaningful replies already posted. One client even DM’d us saying, “Man, you’re super responsive.”

No, we weren’t. Our system was.

It’s now running on multiple profiles, saving us hours every week — and keeping conversations alive, automatically. It’s not perfect (only works on the latest post), but it’s a start. A damn good one.
