The Problem
LinkedIn carousels work.
Making them is painful.
Design tools are overkill
Canva, Figma, PowerPoint... just to make 5 slides? You spend more time designing than writing.
Copy-paste nightmare
Writing in one tool, designing in another. Copying text slide by slide. Formatting breaks constantly.
AI gives wrong lengths
ChatGPT writes too much or too little. Headlines overflow. Body text gets cut off. Nothing fits right.
Hours for one post
What should take 10 minutes takes 2 hours. So you just... don't post carousels.
CarouselBot fixes all of this. Your content in, polished carousel out.

Testimonials
What beta testers are saying
“One week ago, this CarouselBot post hit, I got a DM, and in less than a week I’ve a new global client. It wasn’t my most popular post, but the message resonated and the Carousel told the story in a few swipes. Moral: Use CarouselBot weekly.”
Rich Carr“You read a lot about publications, businesses, products etc. wanting to solve ‘real problems’ but it’s less often you see that in practice. I think your CarouselBot does exactly that. You’ve taken a genuine frustration that many people have and you’ve nailed the solution.”
Paul the Human“Couldn’t believe it took 5 minutes from pasting url to final outcome, even in beta. It was a joy to see Karen deploying all these new features lightning fast.”
Filip Sardi“CarouselBot update looks solid. Custom templates + drag-and-drop reordering is the kind of polish that separates ‘tool I try once’ from ‘tool I keep using.’”
Lakshmi Narasimhan“Just tried your CarouselBot, Karen! It has a really nice design and a clean outcome.”
Jenny Ouyang“It was so fun to test. And also interesting to see how the posts perform, carousels are great for driving impressions. And this was way better than my Canva attempt eons ago.”
JHong“Thank you, Karen, both for the shoutout and for creating yet another amazing app...Honestly, this isn’t me promoting my own work; I just want people to realise what an incredible tool you’ve made”
