The problem it solves

Staying on top of comments on your LinkedIn posts takes constant attention, and if you fall behind, engagement drops and conversations go stale. Writing a thoughtful reply to every comment, every time, just isn't realistic when you're busy running the business.

Who it fits

Founders, marketers, or social media managers who post on LinkedIn and want to keep engagement consistent without watching comments all day.

How it works

  1. Checks your LinkedIn post for new comments every 10 minutes
  2. Filters out comments that have already been answered
  3. AI drafts a short, professional reply to each new comment
  4. Posts the reply back to LinkedIn automatically
  5. Logs the comment, reply, and details to Google Sheets for tracking
What you get

Comments answered within minutes of posting

You get every new comment on your LinkedIn posts answered with a professional AI reply within minutes, keeping engagement active around the clock.

What you get

Timely replies posted under every new LinkedIn comment, plus a Google Sheets log of every interaction.

What you need

A LinkedIn account with API access, an OpenAI API key, and a Google account for Sheets.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
