About aiCarousels
aiCarousels focuses on speed: it turns a topic, text, a website, a YouTube video or a PDF into a carousel from customisable templates. It has a free plan, and its Pro plan adds extra generators such as posts, infographics and quote cards.
What Chartin does differently
It reads the whole article first
Before any slide exists, Chartin writes a technical analysis of the post: the system, the numbers, the cause and effect. That analysis is the source of truth for everything after it.
You pick the story
It suggests several angles (how it works, the incident, the trade-off, the lessons) and the audience (engineers, developers or non-technical readers). The carousel is built for that choice.
Diagrams made for this article
A request's path through a system, an incident timeline, a before and after, a code excerpt: the visual on each slide is drawn from the article's own facts, not a stock template.
A seven-slide story, tested on a cold reader
Each slide answers the previous one's question. An AI reader who never saw the article reads the slides and reports where it got lost, and the carousel is revised before you see it.
Which should you pick?
Pick aiCarousels if
- You want a carousel in seconds on any subject, from many kinds of input.
- You post on Instagram and TikTok too.
- A clean template design is all you need.
Pick Chartin if
- Your carousel has to explain engineering accurately to readers who never saw the article.
- You want real diagrams (architecture, flows, timelines) made for this article.
- You care more about a carousel that teaches than one that's instant.
Pricing
Chartin: your first carousel is free. After that you buy credit packs: 2 carousels for $7, 5 for $15, 15 for $36, 40 for $80 or 100 for $180. Credits never expire and there's no subscription. See pricing.
aiCarousels: Pro subscription (price not shown on its home page; third-party listings say about $15/month). Free plan. Check their site for current prices.
Where Chartin is not the right tool
- It makes one format: 7-slide LinkedIn carousels (PNG or PDF). No Instagram, TikTok or video yet.
- It doesn't schedule or publish posts, and has no LinkedIn analytics.
- It's built for technical articles. For motivational posts or general marketing tips, other tools fit better.
- A carousel takes about five minutes, because it reads, writes, tests and revises. Template tools are faster.
- There's no team plan yet.
