A carousel caption has a job no other caption has: it has to make someone swipe. The first slide is the hook, the caption is the second hook, and if neither one promises something on slide two, most people never get there.
Instagram folds the caption after roughly two lines, so the promise goes in the first sentence. “Slide four is the one” does more work than a paragraph explaining what the post is about.

Writing your own
Decide what the carousel promises before you write a word. If slide one is a question, the caption should tighten the question rather than answer it. If the payoff is buried, point at it: naming a slide number is the most reliable swipe prompt there is, because it gives people a concrete destination. Front-load that pointer, because anything after two lines is invisible until someone taps more. Do not narrate the slides one by one in the caption, since that removes the reason to swipe entirely. One call to action, at the end, and only one you will honor. If you want to test three different opening lines against each other, the AI hook generator gives you variants quickly.
For longer educational carousels where the caption carries real detail, check where it folds with the caption length checker, and use the Instagram post generator if the first line is not coming.
Finally, count your slides against the promise. If the caption points at slide seven and the carousel only has six, you have taught people that your pointers are not reliable, which is exactly the habit you were trying to build.
