The problem it solves

Getting a steady stream of Reels out means writing captions, picking hashtags, and manually posting every single video. Keeping track of what has been posted and finding it later adds even more busywork.

Who it fits

A small business, creator, or social media manager who wants a consistent Reels posting schedule without daily manual work.

How it works

  1. A new video appears in a designated Google Drive folder, or one is chosen at random on a schedule
  2. AI writes a caption with hashtags and a call to action, using the file name for context
  3. The video, caption, and link are logged in Airtable
  4. The Reel is posted automatically to Instagram
What you get

Reels captions ready without writing them yourself

New videos in your folder get captioned and posted to Instagram Reels automatically, keeping your feed active.

What you get

A published Instagram Reel with an AI-written caption, plus a logged record in Airtable.

What you need

A Google Drive account, an Airtable account, a Meta Facebook Graph API connection, 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.
