Slidler vs aiCarousels vs PostNitro
Pick Slidler if you want a free carousel from a link, video or text right now, with no account and no export cap. Its trade-off is a rule-based splitter instead of an AI writer, plus a small slidler.com mark. Pick aiCarousels (PRO $14.95/month) if you want an AI writer that also starts from a topic or PDF. Pick PostNitro (from $15/month; scheduling from $30) if you want brand kits, AI images and posting straight to LinkedIn and Instagram.
