The task
Your last carousel got 18k reach but only 14% completion. People scrolled past slide 2 and never saw the actual content. Slide 1 was the title slide (“AI Prompts 101”). Slide 2 was a “here is what we will cover” agenda. Slide 7, where the real payoff was hiding, got viewed by 1 in 8 people. Saves were terrible because most people never saw the save-worthy slide. You want a 7-slide script that earns the swipe through structure — slide 1 hooks, slide 2 delivers a concrete fact (not setup), slide 6 lands the surprise, slide 7 asks for the action. Pull-through engineered into the content; no “swipe →” arrows pretending to do the work.
Where AI helps — and where it does not
AI is good at structuring the carousel along an attention curve — placing the hook, the build, the surprise payoff, and the CTA at the right slides. It is also useful for writing slide copy at the right density per slot (slide 1 needs 4-6 words, slide 4 can carry 25 words, slide 7 needs 8 words and a clear ask). Where AI fails: designing the visual. Carousel is half copy and half design; the script tells you what to write, but the slide layout, type hierarchy, and color decisions belong to a designer or a Canva template. Carousels that lose at slide 2 sometimes lose because the type is too small to read on a phone, not because the copy is weak.
A common failure mode: the model writes slide 1 as a title and slide 2 as an agenda. Both are wasted. Slide 1 must be a hook with a curiosity gap that slide 2 closes; slide 2 must deliver one concrete fact, not “here is what we will cover.”
What to feed the AI
- The single concept the carousel teaches in one sentence — narrower is better; “5 AI prompt patterns” beats “how to use AI”
- Audience level — beginner / intermediate / expert; the same concept needs different examples per level
- The specific action you want at slide 7 — save, comment, click bio link, share to story; each has different copy
- One past carousel of yours that performed well (tone anchor) — paste the actual slide text
- The format constraint — 4:5 vertical, square, or 9:16 reels-style carousel
- The number of slides — 7 is the sweet spot, 10 is the ceiling before the algorithm caps reach
- The “save trigger” — a specific reason to save (a reference list, a framework, a checklist, a prompt template)
- The hard avoid list — no “swipe →” arrows in the script, no “100% of people,” no emoji unless your brand uses them
Copy-ready prompt
Write a 7-slide Instagram carousel script.
Concept (one sentence, narrow): {paste}
Audience level: {beginner / intermediate / expert}
Action at slide 7: {save / comment / click bio / share to story}
Past carousel that performed (tone anchor): {paste actual slide text or "first carousel"}
Format: {4:5 vertical / square / 9:16}
Save trigger: {what specifically would make someone save this — list, framework, prompt}
Banned: {"swipe →" arrows, "100% of people," "this changed my life," emoji-only slides}
For each slide return:
1) Slide number + role (hook / build / payoff / CTA)
2) Headline — under 6 words for slide 1, under 8 words for slides 2-6, under 8 words for slide 7
3) Body copy — slide 1 ≤10 words, slides 2-5 ≤25 words, slide 6 ≤20 words (the surprise lands with fewer words), slide 7 ≤15 words
4) Reason this slide pulls the reader to the next slide — written into the content, not into an arrow
5) Visual idea in one sentence — what the slide image / illustration should show
Structure:
- Slide 1: hook with a curiosity gap. Make the reader feel "I do not know the answer and I need to know it." NOT a title slide.
- Slide 2: deliver one concrete fact that closes the slide 1 curiosity gap and opens a new one. NOT an agenda slide.
- Slides 3-5: build the argument or list. Each slide must work on its own; readers who skipped slide 4 should still get value from slide 5.
- Slide 6: the unexpected payoff or surprising counterpoint. This is the save slide.
- Slide 7: CTA. The action must be answerable in one tap (save), one sentence (comment), or one click (bio).
End with: which slide is the most likely drop-off point in this draft, and what you would change in design (not copy) to reduce it.Shorter variant — single-slide rewrite
Below is slide {N} of my carousel: {paste copy + role in structure}.
Its job in the carousel is: {hook / build / surprise payoff / CTA}.
The audience drop-off at this slide is {N%}.
Rewrite the slide to better serve its job. Return 3 versions ranked by strongest pull-through. Do NOT add "swipe →" — the pull is in the content.Sample output
A strong slide 1 that earns the swipe: “Why 90% of carousels die at slide 2.” — curiosity gap (why?), specific number, the reader genuinely does not know the answer.
A useful slide 2 that closes the gap: “Slide 1 promised a payoff. Slide 2 usually delivers an agenda. Brains skip agendas. The fix: deliver one concrete fact on slide 2, not ‘what we will cover.’” — closes the slide-1 curiosity, opens a new question (what fact for my concept?).
A useful slide 6 (surprise payoff): “The carousel that performs best in 2026 has only 5 slides and a paragraph CTA on slide 5. Long carousels are 2023 thinking.” — counterintuitive, save-worthy.
A useful slide 7 CTA: “Save this if you publish carousels weekly. The slide structure works on any topic.” — direct action, names the audience, justifies the save.
How to refine
- If carousel completion is below 30%: “Slide 2 is the problem. It must deliver one concrete fact, not a setup. Rewrite slide 2 to close the slide-1 curiosity gap and open a new question for slide 3.”
- If saves are low but completion is high: “Slide 6 or slide 7 is the problem. Slide 6 needs the save trigger (a reference, a checklist, a framework); slide 7 must explicitly tell the viewer why to save.”
- If slide 1 reads as a title: “Rewrite slide 1 as a question or a contrarian statement, not as the topic of the carousel. The reader should feel they cannot guess the answer.”
- If the “reason to swipe” feels artificial: “Rewrite the slide so the reason to swipe is embedded in the content. ‘Curious why? Slide 3 →’ is artificial; ending slide 2 with a half-truth that slide 3 completes is embedded.”
- If slide text is too dense: “Each slide must be readable in 4 seconds on a phone. Cut any slide where body copy exceeds the target word count.”
Common mistakes
- Slide 1 as the title slide: wastes the most valuable real estate; readers see “AI Prompts 101” and skip because they cannot guess what is new about this version.
- Slide 2 as an agenda: brains skip agendas; if slide 2 does not deliver a fact, the carousel is over for 60% of viewers.
- Same text density on every slide: the brain craves rhythm; alternating dense and light slides keeps attention more than uniform density.
- CTA on slide 6, not slide 7: never assume viewers see the last slide; CTA placement should match the slide most people actually reach, which is slide 6 on poorly-built carousels but slide 7 on well-built ones.
- “Swipe →” arrows doing the work: the arrow is a sign of weak content; if you need an arrow to make people swipe, the slide failed.
- No save trigger anywhere: a carousel that does not deserve a save will not get one; engineer the save into slide 6.
- Same hook pattern as your last 4 carousels: viewers learn the pattern and the algorithm shows them less; vary the hook structure every 2-3 carousels.
- No mobile readability check: body text at 24pt looks great on desktop, unreadable at 4:5 on a phone; design for the smallest screen the carousel will be viewed on.
FAQ
- How many slides maximum?: 7-10 is the range; over 10 the algorithm caps reach. The sweet spot is 7 for most concepts; 10 only when the content genuinely requires it (a step-by-step framework, a multi-part case study).
- Square or vertical carousels?: Vertical 4:5 takes more screen, gets more saves, and outperforms square in nearly every category. Use vertical unless brand visuals demand square.
- Should the cover slide have the brand logo?: Tiny, in a consistent corner. Big logo on slide 1 reads as a stock-photo template and hurts swipe rate.
- What about reels-style 9:16 carousels?: Newer format, currently underused, gets a temporary algo boost on some accounts. Test against your 4:5 baseline; do not assume the win transfers across audiences.
- How do I measure if a carousel worked?: Completion rate (slide 7 views / impressions) and save rate (saves / impressions). Comments are a bonus, not the primary metric; algorithm currently weights saves and shares highest for carousel reach.
