How to Make Reddit Comment Carousels

Why does this format work?

• The question does the hooking. "People who clean hotel rooms, what's the strangest thing a guest left behind?" is a promise of a dozen answers, and the viewer wants all of them.
• Every swipe is a signal. Each comment is its own slide, so a viewer reading to the end has interacted with the post once per answer, which a passive view never is.
• It reads like something real. A comment card with a subreddit header looks like a screenshot someone sent you, which is exactly how these get shared on.
• Only the cover is drawn. No narration, no render, and one picture per post — the comment slides sit on a blurred copy of it — so it costs about a third of an illustrated carousel to run every day.

How to make one

1. Ask a question with many different answers. The best ones ask people in a job, a place or a situation what they saw. Avoid questions with one right answer, and questions that invite opinions rather than stories — an opinion is not worth a swipe.
2. Make the cover a headline, not the question. The cover is what the grid shows and what decides the first swipe. "Hotel cleaners reveal the strangest thing a guest left behind" says who is talking and what you get; the question itself lives on the slides.
3. One person's story per slide. Two answers telling the same story is a slide wasted. Each comment should be a different person with a different thing that happened to them, told the way someone actually types it.
4. Put the best answer first. The opposite of a video, which saves its sharpest line for the end. The second slide is the one deciding whether the third is seen, so lead with the answer that makes someone keep going.
5. Use the reply sparingly. One reply under a comment can add the detail that lands it, or ask the question the viewer is asking. More than one and the slide becomes a wall of text.

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. Instagram carousels posted through the API carry no sound at all, so the first answer has to hold the viewer on its own.

How Mediasynth automates it

Pick a tone — shock, story, curiosity, educational, or controversy — and how many slides, and Mediasynth keeps a queue of AskReddit-style questions that fit, writes a hook for the cover and a different first-hand answer for every slide, draws the cover in the art style you choose, sets each comment on a Reddit-style card over a blurred copy of it, and posts the set natively as a TikTok photo post and an Instagram carousel, with TikTok adding a track if you want one. Every username on the cards is invented, so no real Redditor is quoted.
