How to Make AI Carousel Posts

Why does this format work?

• Every swipe is a signal. A viewer who swipes to slide eight has interacted with the post eight times, and both platforms read that as interest in a way a passive view never is.
• It gets saved. Tips, steps and lists are things people want to come back to. A save is the strongest thing a viewer can do short of sharing, and carousels earn more of them than almost any video.
• It reaches a second feed. Photo posts are surfaced alongside videos rather than instead of them, so a channel posting both has two ways into the same viewer's day.
• Nothing has to be voiced. No narration, no render — a carousel is pictures and words, which makes it the cheapest format to run every day.

How to make one

1. Make slide one a promise. It is the cover, and on a profile grid it is the only slide anyone sees before deciding. Say what the viewer gets by swiping — "Five jobs on a lighthouse nobody warns you about" — in words they take in at a glance. A subject on its own ("Lighthouses") is not a reason to swipe, and "swipe to learn more" asks for the swipe instead of earning it.
2. One idea per slide. A slide is read in about three seconds. If it needs a second sentence to make sense, it is two slides — or it is the one to cut.
3. Let the picture show what the text says. The image behind a slide is the scene the words are about — the keeper winding the lamp at night, not a diagram of the idea. When the picture just restates the text, the slide has one idea and a wasted image.
4. Keep the calls to action out of the slides. Hashtags and "follow for more" belong in the caption. On a slide they spend the viewer's three seconds on you rather than on the thing they came for.
5. Put the best one last. The strongest tip, the turn of the story, the #1 on the countdown. The last slide is the reason someone swiped all the way through, and it is what decides whether they save the post.

Which kind of carousel to make

Five shapes cover most of what works. A listicle — things nobody tells you, signs of, mistakes people make. A mini story told a slide at a time, with the turn arriving late. A how-to with numbered steps. A ranking that counts down to a #1 worth arguing about. And myth versus fact, where each slide states a common belief and corrects it. They render and post the same way; what changes is how the words are written.

What about music?

On TikTok, a photo post can carry a track — TikTok picks one when the post goes up, and you can swap it in the app afterwards. No app can choose the song for you through TikTok's posting API. Instagram carousels posted through the API carry no sound at all, so the slides have to hold the viewer on their own — which is one more reason the first one has to be a promise.

How Mediasynth automates it

Pick a kind — listicle, mini story, how-to, ranking, or myth versus fact — and how many slides, and Mediasynth keeps a queue of subjects that fit, writes each slide under the rules above, draws a picture for every one in the art style you choose, sets the text over it in your channel's font and language, and posts the set natively as a TikTok photo post and an Instagram carousel, with TikTok adding a track if you want one.
