1. Who writes the slides
On PostNitro, the AI model depends on your plan, and Starter gets “basic AI models”. Writing is counted in tokens: 400K a month on Starter, 1.2M on Creator+.
On aiCarousels you pick a writer instead of a model. Each of the 19 ghostwriters has a voice of their own, from a candid founder to a patient teacher, and writes every slide and the caption. They don’t make up numbers, quotes or clients: put your facts in a brand kit and they use those.

2. Who designs them
PostNitro’s editor works as “pick a template, then drag, resize and layer anything on it”, and its 100+ templates are “all 4:5”. Every slide is a canvas you arrange.
On aiCarousels the design comes with the words. Each slide gets one of 304 layouts that fits what it says, for lists, steps, quotes or charts, in one of 95 themes, sized for the platform you post on. You can still move anything by hand, with 80 undo steps.

5. What else comes with Pro
- Text posts. Your writer writes LinkedIn text posts too, offers three other first lines and shows where “…more” cuts it.
- Image posts. One idea comes back as several designed image posts to pick from.
- Video posts. Your words over a moving clip, or any carousel as a swipe video, for Reels, TikTok and Shorts.
- Start from what you already made: a web page, a YouTube video, a PDF, your notes, or slides you wrote in ChatGPT or Claude, in any of 27 languages.
- Your brand on every slide. 10 brand kits on Pro, 50 on Team, with your colours, fonts, logo and the facts your writer may use.
- Posts you saved, made yours. Save a post from LinkedIn, Instagram or TikTok with the Chrome extension, and your writer makes one like it about your topic.
6. The verdict
PostNitro gives you templates and a canvas, and asks you to move up to Creator+ for posting and to Team+ for 20-slide carousels. aiCarousels writes, designs and posts the carousel on Pro, for the same $15 a month as PostNitro Starter.
If you want the post finished rather than started, aiCarousels is the one to pick: a ghostwriter writes every slide and the caption, 304 layouts and 95 themes do the design, and Pro makes carousels of up to 20 slides with 100 AI pictures a month, then posts them to your LinkedIn profile. And it doesn’t stop at carousels: the same writer makes image posts, video posts for Reels and TikTok and text posts, in one app and on one bill. aiCarousels was the first AI carousel maker, in 2023, and it has kept pushing ever since. When you write in, the founder answers.
