3.9M views: how to make “hidden engineering” 3D build reels with Claude

A step-by-step guide to this format: what @hiddenhome.3d does, why a reel with 3.9M views works, the Claude prompts to make your own version, and how postreadygo posts one every day at the best time on every platform.

“How a driveway becomes a jet engine bunker.” A normal house, a ridiculous goal, and every step shown as a serious 3D cutaway. The reel has 3.9 million views; the account posts a new build every day and its top reel is at 29 million.

What Claude is and how to get an account

Claude is an AI assistant made by Anthropic. It can research, write scripts and prompts, and write the code that draws an animation in your browser.

  1. Go to claude.ai or install the Claude app.
  2. Sign up with your email address or your Google account.
  3. Type your first message in the box at the bottom.

Step 1: Claude plans the build

Claude plans the build prompt

Write “How a driveway becomes a jet engine bunker” as 7 serious engineering steps.
One short sentence per step. Keep it playful, not a real building guide.
Give me 20 more “how a normal thing becomes an absurd thing” ideas.

Read what Claude gives you and change anything that does not sound like you.

Step 2: Claude models each step

Claude models each step prompt

Build this as a single HTML file with three.js, vertical 1080x1920.
A simple house and driveway with the ground cut open. Add each step as a new object, one at a time.
One-word captions. Add a Record button that downloads the video.

If something looks wrong, tell Claude what you see and it fixes it.

Why posting by hand holds you back

  • Five apps, five uploads. The same video, the same caption, again and again for Instagram, TikTok, YouTube, Facebook and Threads.
  • The wrong time. You post when you remember, not when your audience is online.
  • One busy day breaks the streak. Then two, then a week, and the account stops growing.

With postreadygo, one message to Claude schedules a whole month: one video a day, each at its best time, on every platform at once. That is 30 posts a month per platform, without opening a single app.

Step 3: Connect postreadygo to Claude

  1. Go to postreadygo.com and click Get started for free. Then open Linked and connect Instagram, TikTok, YouTube or any other supported network.
  2. In Claude, open Settings, then Connectors, then Add custom connector.
  3. Name it postreadygo and paste: https://www.postreadygo.com/mcp
  4. Click Connect, sign in to postreadygo and press Allow.
  5. Test it: “List my postreadygo accounts.”
