How the work actually flows

It branches. Exactly one path is taken.

The problem it solves

Answering every new post in a busy community takes constant attention, and questions get missed when you're not watching closely. Keeping track of what you've already responded to gets messy fast without a system for it.

Who it fits

Financial advisors, brokers, or content marketers who want a steady, consistent presence answering questions in a specific online community.

How it works

  1. A new post appears in the subreddit you're monitoring
  2. AI reads the post and drafts a short, helpful reply
  3. The system checks a log to confirm that post hasn't already been answered
  4. The reply is posted to Reddit automatically
  5. The post and reply are logged in Google Sheets for review
What you get

Steady, helpful presence in your community

You build a steady, helpful presence in your subreddit, with a thoughtful reply ready every time someone posts a relevant question.

What you get

A posted reply to each new relevant question and a spreadsheet log of every comment made.

What you need

A Reddit account, a Google account, and a Google Gemini API key.

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.
