An AI carousel generator writes the slides and builds the design from a topic, a link or your own text. Nearly all of them do that. What changes from one to the next is what comes before and after: where it gets the subject from, whether it applies your brand, whether it publishes to Instagram or just hands you the files, and what the free plan lets you download.
I'm the founder of Dalea, so it's on the list and you should read the rest knowing that. In return, I'll say where each competitor is better than us.
The quick answer
- You don't know what to post and want the carousel made and published: Dalea.
- You want a carousel-only tool that publishes to several networks: PostNitro.
- You want lots of layouts and to pay little for 60 carousels a month: aiCarousels.
- You want to turn a YouTube video, a Reel or a thread into a carousel: Contentdrips.
- You already have a deck or a blog post to turn into a carousel: Gamma.
- You make infographics and other visuals besides carousels: Piktochart.
How I picked these six
Not by taste. Twice a week I ask ChatGPT and Gemini, in nine languages, what the best AI tool is for generating Instagram carousels from a topic, and I record which sites they read to answer. Across 144 answers, between October 11 and November 8, 2026, the most read were PostNitro (73 answers), aiCarousels (59), Piktochart (58), Gamma (52) and Contentdrips (35).
One was left out: Apaya showed up in 40 answers, but it's a social media autopilot starting at $69 a month, where the carousel is just one of the formats and has 3 or 5 slides. Dalea is here because it's what I build; it was mentioned in 1 of those 144 answers.
One limit you should know about: I didn't use each tool for weeks to write this. What's here is what each site states, checked on November 9, 2026.
The 6 generators side by side
| Tool | Starts from | Publishes to Instagram? | Free plan | Entry price |
|---|---|---|---|---|
| Dalea | An idea from your calendar, a link or a PDF | Yes, and to TikTok | No | $14.90/month or $49.90/year |
| PostNitro | Topic, article link, text or an X post | Yes, from $30/month | Yes: 5 downloads a month, watermarked | Starter $15/month |
| aiCarousels | Topic; link, YouTube and PDF on the paid plan | No: you download and post | No: 1 trial carousel, no download | Pro $15/month |
| Contentdrips | Topic, blog, YouTube, Reel, thread or spreadsheet | Yes | The site says both free plan and 7-day trial | Starter $19/month |
| Gamma | Topic, blog link or an existing deck | No: exports PDF or images | Yes: 400 credits, once | Plus R$40/month (shown to me in Brazilian reais) |
| Piktochart | Topic, pasted text or a document | The site doesn't say which networks | Yes: 2 PNG downloads | Pro $15/month |
1. Dalea: the carousel comes from your calendar and goes to your profile
Best for: people who run their own profile and get stuck before the design, at "what do I make the carousel about?".
Dalea sets your profile's strategy and builds the content calendar, so the idea for the carousel already comes from there. You can also start from a link or a PDF. The AI carousel generator writes 3 to 10 slides, with a cover, the content and a closing call to action, and applies your Brand Kit: colors, fonts and logo, which it extracts from your website or from a brand guide in PDF. You edit the text, ask for changes in chat and, if your text is already written, use the mode that keeps your words and only creates the visuals.
At the end you download the slides as 1080 × 1350 PNGs or publish and schedule to Instagram and TikTok. The plan includes 30 carousels a month, 20 edited videos in the automatic video editor, unlimited scripts and a profile analysis that shows which hooks and formats worked.
Where it falls short: there's no free plan, it exports PNG only (no PDF or video), it generates up to 10 slides per carousel and follows Dalea's layouts, with less design freedom than the dedicated tools. It only publishes to Instagram and TikTok, and it's one brand per plan.
Price: $14.90 a month or $49.90 a year.
2. PostNitro: carousels only, publishing to six networks
Best for: people who want a dedicated carousel tool and post on several networks.
PostNitro generates the carousel from a topic, an article link, text you already wrote or an X post, and lays the slides out on your brand kit (fonts, colours, logo and headshot). It has 100+ editable templates, exports PNG, PDF or MP4, and publishes natively to Instagram, LinkedIn, TikTok, Threads, Facebook and Pinterest. For client work there's a workspace per client with approval before publishing, plus an API and connectors for ChatGPT and Claude.
Where it falls short: publishing only starts at the Creator+ plan, $30 a month; Free and Starter design and export but can't publish. The free plan is limited to 5 slides per carousel and 5 downloads a month, with a watermark. The site doesn't mention analytics.
Price: free plan; Starter is $15 a month; Creator+ is $30 a month; Team+ is $60 a month. A Black Friday promotion was running on the day I checked.
3. aiCarousels: lots of layouts for little money
Best for: people who want volume and design variety and don't mind posting by hand.
It's a tool built only for carousels. The Pro plan gives 60 AI carousels a month, up to 20 slides each, and takes a link, a YouTube video, a PDF or pasted text as the starting point. The site lists 304 slide layouts and 95 ready-made looks, and says its AI writers work from your facts and never invent numbers or quotes. It exports PDF, PNG and MP4, and there's a $99 lifetime plan for people who bring their own OpenAI key.
Where it falls short: it doesn't publish to Instagram: you download the PNGs and post them. Direct publishing is LinkedIn only, and the site doesn't mention scheduling. There's no real free plan: the trial generates one carousel, which you can edit but not download.
Price: Pro is $15 a month, or $120 a year; Team is $59 a month for 5 people.
4. Contentdrips: from video, thread or blog to carousel
Best for: people who repurpose content that already exists in another format.
Contentdrips takes the widest range of starting points of the six: a topic, a blog article, a YouTube video, a TikTok or Reel link, a thread, a podcast transcript and even a spreadsheet for bulk generation. It applies your brand kit, exports PNG, PDF, GIF or MP4, and schedules and publishes to LinkedIn and Instagram. It has a calendar per brand, an API and Zapier and Make integrations.
Where it falls short: it leans towards LinkedIn, and TikTok publishing is listed as "coming soon". The site doesn't mention analytics. On the free tier it contradicts itself: one part says free plan, another says a 7-day trial with 50 credits.
Price: Starter is $19 a month, or $15 a month billed yearly, with 1,500 AI credits a month (a carousel costs 10); Pro is $35 a month, or $29 billed yearly.
5. Gamma: from deck to carousel
Best for: people who already use Gamma for presentations or have a deck or blog post to reuse.
Gamma is an AI builder for presentations, documents and websites that also has a social format. You type a topic, paste a blog link or upload an existing deck, and it lays out the cards, writes the copy and applies your brand. It exports a PDF or an image pack, as well as PowerPoint and Google Slides.
Where it falls short: it doesn't publish or schedule: you export and upload to Instagram. It isn't a carousel tool, and usage is metered in credits without saying how many a carousel costs. The free plan gives 400 credits once, with Gamma's branding on the slides.
Price: free plan; Plus is R$40 a month and Pro R$100 a month. Gamma's site showed me prices in Brazilian reais, and I couldn't confirm the US dollar amounts there.
6. Piktochart: a carousel maker inside a design platform
Best for: people who also make infographics, reports and presentations.
Piktochart is a visual design platform, and the carousel maker is one of its several AI generators. You describe the topic, paste text or upload a document, and you get an editable draft with structure, copy and visuals. Around it there's a full editor with charts, maps, icons and team collaboration.
Where it falls short: the brand kit (colors, fonts and logos) only exists on the Business plan, and so does PDF export. The free plan allows 2 PNG downloads. The pricing table mentions social media publishing, but the site doesn't say to which networks.
Price: free plan; Pro is $15 a month, or $10 billed annually; Business is $20 a month, or $17 billed annually. Prices are per member.
How to choose yours
Three questions settle it.
- Where does the subject come from? If you already have the content in another format, Contentdrips (video, thread, blog) or Gamma (deck). If the hard part is deciding the subject, only Dalea starts from your profile's strategy and results.
- Who publishes? Dalea, PostNitro (from $30 a month) and Contentdrips publish to Instagram. aiCarousels and Gamma hand you the files.
- How much do you post? For high volume at the lowest price, aiCarousels (60 a month for $15). To try without paying, PostNitro and Piktochart have free plans that let you download, with limits.
