What is the best AI carousel generator for TikTok?

For TikTok specifically, look for a tool that starts at 9:16 and can publish to TikTok directly, because the slow part is rarely the design. PXT Creator Studio does both. Gamma generates carousels well but is shaped around LinkedIn and Instagram formats, and its flow ends at an export you upload yourself.

Does Gamma post to TikTok?

Gamma's own social media page describes exporting a PDF or image pack ready to upload to LinkedIn, Instagram or your scheduler, so the upload is yours to do. PXT connects to a TikTok account and publishes the finished carousel from the browser.

Can I use an AI carousel generator for free?

Both have a real free tier, and they renew differently. Gamma gives 400 credits at signup, which is a one-time grant rather than a monthly allowance, allows up to 10 slides per prompt, and leaves Gamma branding on your output until you upgrade. PXT's free Starter plan renews 5 AI generation credits every month alongside 50 active posts, 50 images and one connected TikTok account, and watermarks exports at standard quality.

What size should a TikTok carousel be?

9:16 vertical at 1080 x 1920 pixels, the same as a TikTok video. Square or landscape slides get letterboxed or cropped. Keep important text inside a centre safe zone so the caption and buttons do not cover it.

Is there an AI tool that turns a topic into TikTok slides?

Yes. Describe the post in a sentence and PXT's AI outliner returns the slide breakdown, the text for each slide and a background image per slide, already at 9:16. You edit anything you want to change, then publish. The prompt works like a brief, so naming your audience and the slide count gives a much more usable first draft than a bare topic.

PXT Creator Studio vs. Gamma

Gamma turns ideas into decks, documents and social posts, then exports a file for you to upload. PXT does one thing: vertical carousels, sized for TikTok, published straight to it.

Where the carousel actually ends up

Both tools do the same thing for the first ten minutes. You describe the post, the AI returns a set of laid-out slides with the words already written, and you edit what you want to change.

They part company at the end. Gamma's own description of the flow finishes with exporting a PDF or an image pack, ready to upload to LinkedIn, Instagram or a scheduler. That last step is yours: download the file, move it to your phone or into a scheduler, select the images in the right order, check they went in the right order, post.

PXT connects to your TikTok account. When the carousel is finished you publish it, and that is the end of the process. If you post once a month the difference is a minor annoyance. If you post several times a week it is most of the work.

Which platform the formats are shaped for

Gamma names LinkedIn carousels, Instagram posts and vertical stories as its social formats. That is a coherent set, aimed squarely at people building a professional presence, and if that is your audience it is the right shape.

PXT starts every project at 1080 x 1920 and has no other mode. Templates, text placement and the safe-zone margins all assume a full-screen vertical feed, because that is the only thing it makes. TikTok appears in Gamma's world as a channel; in PXT it is the destination the product is built around.

If your posts go to TikTok, one of those is already the right shape and the other needs adapting on every post.

One product against six

Gamma makes presentations, documents, websites, graphics, an API, and social content. Social is the newest of the six. That breadth is genuinely useful if your week involves a pitch deck on Monday and a carousel on Thursday, and it means one subscription instead of two.

It also means social competes for attention with five other products, and their credits are shared across all of them. PXT makes vertical picture carousels and nothing else, so every decision in it, down to where the text sits by default, is made for that one job, and every credit you have goes into it. If you post carousels constantly, spreading a budget across six products is the expensive option, whatever the sticker price says.

What you give up

Gamma takes more kinds of input: a topic, a blog post URL, or an uploaded deck. PXT takes a typed topic, so if your carousels come from writing you have already published, that gap is real. Gamma also carries a much larger theme library and ships a public API.

What you get instead

PXT Pro is $119.99 a year. Gamma Plus is $108 and Gamma Pro is $216, so we sit between their two main tiers, and what you are choosing between is spread against depth.

Gamma Plus buys 1,000 credits a month spread across presentations, documents, websites, graphics and social. PXT Pro buys 200 posts and 200 images a month, 100 AI credits, three connected TikTok accounts, ten custom templates, 1080p exports with no watermark, and the thing none of their tiers include at any price: the carousel goes to TikTok when you finish it, instead of becoming a file you upload.

Their free tier is worth reading carefully too. The 400 credits are granted at signup, not monthly, and Gamma branding stays on your output until you pay. PXT's free plan renews 5 AI credits every month, includes a connected TikTok account, and publishes. Both watermark until you upgrade; only one of them refills.

If your posts go to TikTok, this is not close

Gamma is a good product and a genuinely capable generator. It is shaped for LinkedIn and Instagram, social is the newest of six things it makes, and its flow ends at an export.

PXT makes vertical carousels and nothing else, at TikTok's size, published to TikTok. If that is where your posts go, every part of the tool is already pointed at it, and you can confirm that on the free plan before paying anything.

Prices above are Gamma's published Individual plans on annual billing, checked 9 August 2026. Monthly billing costs more, and any of this can change.

The bottom line

Gamma spreads its credits across six products and ends at an export you upload yourself. PXT spends everything on one format: 9:16 by default, styling that holds across the set, and the finished carousel published straight to your TikTok account. If TikTok is where your posts go, that last step is the whole difference.
