Generate Instagram & TikTok carousels with AI

Type a topic. AI writes every slide and renders the images in your brand style. Review, then schedule to Instagram and TikTok.

Used by social teams across X, Instagram, LinkedIn and TikTok

Sarah Mitchell

"We draft a week of LinkedIn and Instagram captions in about 15 minutes. The AI keeps our brand voice once we paste in three reference posts."

James Rodriguez

"I run 5 client accounts on the Business plan. 500 AI credits a month is enough to draft posts for X, Instagram and TikTok without running out mid-month."

Emily Chen

"Image generation on Premium covers our weekly LinkedIn carousels. Hashtag suggestions are tuned per platform, which saves the manual research step."

AI carousel generator: questions and answers

Platforms, styles, editing and pricing.

Which platforms does it support?

Instagram and TikTok carousels today. Each slide is rendered at the right size for the platform you choose.

Does it create the images, or just the text?

Both. The AI writes the slide text and PostNext renders finished slide images in your brand colours and logo, so there is nothing to design.

What styles are available?

Four: TikTok (bold caption look), Branded (your colours and logo), Editorial (clean and light), and Photo (text over an image background).

Can I edit a carousel after it is generated?

Yes. Edit any slide's text, the caption and hashtags, switch the style, or reshuffle the backgrounds, then re-render.

Does it use my brand colours and logo?

Yes. The Branded and Editorial styles pull your brand colours and logo from your PostNext brand profile.

How do I publish a carousel?

Send it to your drafts and schedule it alongside your other posts on the PostNext calendar for Instagram and TikTok.

Is it free?

Carousel generation is available on PostNext's paid plans, with a free trial. See the pricing page for current plans.

How many slides does a carousel have?

Usually four to six slides, and always at least two, since Instagram needs two or more slides for a carousel.
