The Claude Carousel Engine: turn one messy idea into a 10-slide carousel people actually save

A prompt that pulls the carousel out of your head, builds the staircase, then tells you which step is weak.

A carousel is a staircase, and most people build it with a step missing.

You've got the idea. You open Canva, type something on slide 1, and then you sit there for 40 minutes moving a text box 2 pixels to the left.

The problem isn't your design. It's that you started building the staircase before you knew where it was going. Slide 3 repeats slide 2, slide 6 is three ideas wearing a trench coat, and by slide 8 you've quietly changed the subject. Your reader climbs, hits the gap, and swipes away. That's the cost. Not a bad post, a post that nobody finishes, which the algorithm reads as "not worth showing to anyone else."

Most carousel prompts floating around make this worse. You give them a topic, they hand back 10 slides of confident beige that could belong to any account in your niche. This one does the opposite. It asks you 5 questions first, because the good bits are already in your head and Claude can't guess them.

What's inside

  • A 4-step prompt that interviews you, maps the staircase, then writes the copy
  • 5 hook options per carousel, each built on a different psychological angle
  • A self-critique step where Claude tells you which slide would lose the reader

What you need

  • Claude (the free plan handles this fine)
  • One idea you can say out loud in a messy sentence
  • 15 minutes, most of it answering questions

The prompt

I run every carousel through this before it touches Canva. The staircase step takes 2 minutes and saves me the 40.

Prompt
You are a carousel architect. Your job is to turn one idea of mine into a 10-slide Instagram carousel that a stranger saves and sends to a friend.

Three rules that override everything else:
1. You are not supplying my opinions. You are structuring mine. Where you need something only I know, ask me instead of inventing it.
2. One idea per slide. If a slide needs the word "and", it's two slides.
3. If a line could sit unchanged on a competitor's carousel, it's dead. Rewrite it with something specific to me.

STEP 1. Interview me.
Ask these 5 questions ONE AT A TIME. Wait for my answer before asking the next. Do not move on until you have all 5.
1. What's the idea, in one messy sentence? Don't tidy it up for me.
2. Who is the one person reading this, and what did they try last week that didn't work?
3. What do you know about this that most people in your niche get wrong?
4. What should they do or believe differently by slide 10?
5. What proof do you have? A number, a result, a client, a story, a mistake you made.

STEP 2. Show me the staircase before you write anything.
Give me 10 one-line slide labels in order, so I can see the logic from a distance. Under it, tell me in one sentence what the reader is feeling at slide 3 and at slide 7. Then ask me to approve, reorder or cut. Do NOT write slide copy yet.

STEP 3. Once I approve the structure, write the carousel.
- Slide 1: give me 5 hook options, 9 words maximum each. One names the cost of getting this wrong. One makes a claim people will want to argue with. One is a question they've already asked themselves at 11pm. One leads with a number. One names the mistake. Label which is which.
- Slides 2 to 9: 12 words maximum of on-image copy per slide, plus a short spoken note underneath I can use for the caption or a voiceover. Build tension across slides 2 to 4. Deliver the actual goods across 5 to 7. Get uncomfortably practical by slide 8.
- Slide 10: one thing they can do today, in under 10 minutes, then one line that invites a specific comment. Never "thoughts?" and never "drop a word below".

STEP 4. Attack your own work.
Tell me:
- Which slide is the weakest and exactly why
- The precise slide where someone swipes away, and what would hold them
- The most generic line in the whole thing, then rewrite it
- One honest reason this carousel might not deserve a save

Formatting: Australian English. No em dashes. Write like a smart friend explaining something at a kitchen table, not like a brand.

How to use it

  1. 1Paste the prompt into a new Claude chat and answer the 5 questions out loud using the microphone button. Speaking beats typing here, because you'll say the specific thing you'd have edited out.
  2. 2Read the 10-line staircase before you read anything else. If the order feels wrong, say so. Reordering at this stage costs you 30 seconds. Reordering after the copy exists costs you the whole draft.
  3. 3Take the hook option that makes you slightly nervous, not the safest one. Then build in Canva.
  4. 4Make it yours: Add one line to the top of the prompt: "My last 3 carousels were about X, Y and Z, so don't repeat those angles." Claude will actively route around what you've already said.

Bonus prompts

Three ways to squeeze more value out of the engine

Bonus: Turn a carousel into a reel without writing it twice

Bonus prompt
Take the carousel we just built. Rewrite it as a 35-second reel script. Give me a spoken hook in the first 3 seconds that is different from the carousel hook (not a rewrite of it), then the voiceover in short spoken sentences, then a b-roll suggestion beside each line that I can film on my phone in my own house. Mark the exact second where the pace needs to change so it doesn't drag.

Bonus: Find out why the flop flopped

Bonus prompt
Here are the 10 slides of a carousel of mine that underperformed [paste them]. Don't be kind. Tell me: was it the hook, the structure, the specificity, or the topic itself? Point at the exact slide where you lost interest. Then tell me the one change that would have made the biggest difference, and whether this idea was worth posting at all.

Bonus: Build a hook bank you can pull from all month

Bonus prompt
Based on the 5 questions I answered earlier, generate 20 carousel hooks I could use across the next month. Group them into 4 columns: cost, contrarian, confession, and number. 9 words maximum each. Then rank all 20 by how likely a non-follower is to stop scrolling, and tell me why the top 3 beat the rest.

Do this today: take the idea you've had sitting in your notes app for a fortnight and run it through step 1 and step 2 only. 5 minutes, and you'll have the staircase. The copy is the easy bit once you can see where it's going.
