One rule, 2,400 seats: how to make “we simulated it” reels with Claude

A step-by-step guide to the simulation reel: an everyday question, one simple rule, and a model that runs it with real numbers. How an account with 36 posts reached about 43,700 followers, the Claude prompts for the simulation and the video, and how postreadygo posts one every day on every platform.

Someone stands up at a concert. Now you cannot see, so you stand, and the person behind you cannot see either. How far does it spread? This account built a model of a 2,400-seat block with real heights and ran it. The account has 36 posts and about 43,700 followers.

The format, and why it works

The account we looked at is @funcheta.studio (Funcheta) on Instagram: 36 posts and about 43.7K followers as of November 12, 2026. Its bio: “Simple rules. Real simulations. Surprising outcomes.”

The three parts of the format.
  • The question is one everyone has lived. You have been in that seat.
  • One rule is enough. “If you cannot see, you stand.”
  • Real numbers make it credible: real heights, a real seat count, thousands of runs.
  • The result is a number, and numbers start arguments in the comments.

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 writes and runs the simulation

Simulation prompt

Simulate this and show me the result: one person stands up in a 2,400-seat concert block.

- Rule: if you cannot see the stage over the person in front, you stand
- Use realistic heights for adults, and a sloped floor
- Run it 5,000 times with a random first person
- Tell me the average number of people who end up standing, and what surprised you

Ask Claude to explain every assumption. Put the important ones on screen: people will ask.

Step 2: Claude turns it into a video

Video prompt

Turn one run into a single HTML file, vertical 1080x1920, 60 seconds.

- A clean white background with black figures in rows
- Start with a side view of 5 seats, then zoom out to the whole block
- The standing people turn red, with a live counter
- One short line of text at the top for each beat
- A Record button that downloads the video

Open it in Chrome and press Record. End on the number, and ask people to guess it in the caption.

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.”

Step 4: One a day, on autopilot

Scheduling prompt

Here are 30 videos.
Post one every day at the best time on Instagram, TikTok, YouTube, Facebook and Threads, starting tomorrow.

Questions people ask

Do I need to know statistics?

No, but be honest about the assumptions. Ask Claude to list them, and show the main ones in the video.

What if people disagree with the result?

Good. Change one assumption, run it again, and post part 2.
