This AI Setup Runs My Social Media While I Sleep

I teach platform-proof monetization: making money online without relying on a single algorithm or platform to pay you. Part of that is being present in many places without doing the work many times. So here’s the setup I built that turns one video into long-form LinkedIn posts, Reddit posts, Instagram images with captions, Twitter posts, and more, automatically.

It took a few hours to build and will take you a few too. Once it’s running, one upload feeds everything.

The Core Loop

I use AI agents inside n8n, an automation tool. The flow:

I upload a TikTok as normal. A repurposing tool spreads the video to YouTube, Instagram, LinkedIn, Twitter, and Pinterest, and saves a copy to Google Drive.
A workflow watches that Drive folder, and when a new file lands, it sends it to Amazon Web Services to transcribe. (I prefer AWS over Whisper because it accepts both video and audio and has a higher size limit.)
The transcript and a summary get saved to Air Table.
Separate per-platform workflows check Air Table about every hour for a new entry marked “not posted.” When one’s found, an AI agent writes that platform’s post, posts it, and flips the record to “yes.”

I keep each platform in its own workflow. It’s called modularization, and it’s the cleanest way to get the most out of AI agents.

The Prompt Rules That Keep It Human

Be very specific with the AI agent’s prompt. Mine:

Uses my tone of voice. The easy way to capture yours: feed a few of your text or audio samples into the AI and let it describe your voice, so the output sounds like you, not a robot.
Says plainly: no jargon, simple language.
Writes at about a sixth-grade level. That’s roughly the average US reading level, and many readers worldwide read English below that, so simple includes more people.
No asterisks for emphasis (AI loves them).
Hard character limits per platform. For Twitter, I check the character count, and if it’s over 280, the workflow loops back and rewrites until it fits.

Images, Automatically

For Instagram, I use a tool called Banner Bear. I upload a background image I made in Photoshop with a text box, and the AI agent’s output drops into that box to create a scroll-stopping image with a search-optimized caption. Instagram’s a little harder because it runs through the Facebook API, but you set it up once and just keep it from breaking.

Why This Matters

One piece of content now becomes text, images, and video across platforms, and I meet people where they are. Someone scrolling LinkedIn on mute still stops for an image. And because the setup already exists, I can spin up a whole new niche (I’m now in a “can dogs eat this” pet niche) without spending more time. The larger and more consistent your presence, the higher your chances of making money, and none of it depends on one platform paying you.

It’ll feel intimidating and frustrating the first time, expect about five hours and some self-doubt. But once you’ve connected the dots once, it gets easier every time, and there’s plenty of documentation (and ChatGPT) to help when you get stuck.
