Turn one idea into a swipeable carousel. A language model drafts the copy for every slide, then an image model that handles text paints each one with the words already in place. Keep a single look across the set, proofread every letter, and export in the format the platform asks for.
A carousel is a short story told one swipe at a time, and most of the work is the writing: a hook for slide one, a single idea on each slide after it, and a last slide that asks for one action. AI can draft that copy and then render every slide with the words already in the image, so your time goes into choosing and fixing instead of laying out ten frames by hand. This page walks through the workflow for Instagram and LinkedIn.
A carousel is expensive in a quiet way. One post means several frames that have to agree on color, type, spacing and tone, and every frame needs its own sentence worth reading. Designers solve that with templates. Everyone else ends up nudging text boxes around until the evening is gone.
AI splits the job into the two parts it handles best. A language model drafts the slide copy from your topic, and an image model that can render text paints each slide with the words in place. Picasso IA keeps both kinds in one workspace: the catalog holds 502 models, including 75 language models and 212 text-to-image models, and all of them run from the toolkit. New accounts get free credits, so you can build a first carousel and see whether the look holds before you pay for anything.
Be clear about what this replaces. It replaces the blank-frame problem and the repetitive layout work. It does not replace the idea. A carousel about something you actually know, with an example only you have, will beat a generic one at any quality setting. If what you need is a single image rather than a sequence, the page on AI social media posts covers that case.
Write the carousel as text first, in a chat model, not in an image model. Language models such as claude-sonnet-5 or gpt-5.4 are good at turning a topic into a sequence, and the sequence is what your reader swipes through. Give the model four things: the audience, the one takeaway, the platform, and a hard cap on words per slide. Then ask for the output slide by slide, with a short headline, at most one supporting line, and a one-sentence note describing the visual.
Keep the cap low. Text on a slide gets read on a phone, in a second or two, by someone deciding whether to swipe again. A headline of a few words and one supporting line is plenty. If a slide needs a paragraph, it is really two slides.
Read the draft aloud before you spend any credits on images. Slide one has to work alone, because in a feed it is the slide most people see. Every later slide must earn the swipe with one new idea, and the last should say one thing to do next: save, comment, follow or click. The platforms pull in different directions here. Instagram readers swipe through visuals with a caption underneath, while many LinkedIn readers treat a carousel more like a short document, so those slides can carry a little more argument. Check each platform's current carousel specs, slide limits and file requirements before you export, because they change and a number quoted here would age badly.
Most carousels that work share the same skeleton, even when the topics have nothing in common. Knowing the role of each slide tells you how much text it can hold and what the image should do.
| Slide role | What it carries | On-slide text | Image approach |
|---|---|---|---|
| Cover | The promise, in one line | Short headline, nothing else | Your strongest visual, the one that stops the scroll |
| Setup | The problem or the context | Headline plus one line | Same look, simpler composition |
| Body | One idea per slide | Headline plus one supporting line | Repeat the layout so the eye learns where to look |
| Proof | An example, a step or a before and after | Short label or caption | The most concrete image in the set |
| Close | The one action to take | A verb phrase | Calm layout with room around the text |
A LinkedIn carousel that reads like a mini slide deck overlaps with AI presentation images, and the same habits apply: one idea per frame, large type, no paragraphs. An Instagram carousel leans harder on the cover and on images that carry feeling, since the caption does some of the explaining.
This walkthrough assumes a topic and an account. Every step happens in the toolkit.
If you want a feel for what a model can do before committing to a style, the effects page shows preset looks that are quick to browse for ideas.
A set of slides reads as one carousel when a few things stay fixed: the background color, one or two type styles, the position of the text, the way images are treated, and the output size. Everything else can change. The style paragraph from step two is where you pin those choices down in words. A useful one is concrete: a flat sky blue background, a white rounded card, a bold sans-serif headline in the upper third, a thin line illustration in the lower right, generous margins.
Ideogram v4 Quality lists consistent styles from descriptive prompts as one of its features, and GPT Image 2.5 Flare accepts reference images, which gives you two ways to hold the look: describe it identically every time, or show the model the slide you already like. If your carousel features a recurring figure, the techniques on the page about consistent AI characters apply directly.
Change one thing per prompt. When slide four drifts, resist rewriting its whole prompt: keep the style paragraph word for word, swap only the headline and the visual note, and run it again. Rewriting everything is how a set of six becomes six different designs.
Generating several options per slide helps more than perfecting a single prompt. GPT Image 2.5 Flare can return multiple images from one prompt, so you pick the one that matches its neighbors instead of arguing with a model about a margin.
This workflow has real limits, and most of them show up around slide five. Know them before you promise a client or a deadline anything.
None of this makes the approach a bad one. It means the last stretch, the proofreading and the final export, stays with you.
Yes, in two stages. A language model drafts the headline and supporting line for each slide from your topic, and an image model that handles text renders each slide with those words inside the picture. You still choose the idea, pick the best options and proofread. Before exporting, check Instagram's current carousel requirements, since slide limits and sizes are the kind of detail that platforms update without much notice.
It can build the slides, and the process is the same as for Instagram: draft the copy, render the slides, keep one look, proofread. The difference is in the writing. Many LinkedIn readers treat a carousel as a short document, so the slides can carry a little more argument and a more professional tone. Check LinkedIn's current requirements for carousel files and formats before you export.
For slides, pick models that advertise readable on-image text. Picasso IA lists ideogram-ai/ideogram-v4-quality and openai/gpt-image-2.5-flare, and the Flare model also describes sharp text rendering and reference-image input. Neither is flawless, so run the same slide through both and keep whichever spells your headline correctly. The catalog has more text-to-image models if neither suits your look.
Write the look once as a style paragraph, covering background, colors, type style, layout and text position, and paste it unchanged at the top of every prompt. Use the same output size for the whole set. With a model that accepts reference images, attach your chosen cover to the later slides as well. Expect some drift anyway and plan to regenerate a slide or two.
As many as the idea needs and no more. A tight carousel of strong slides usually beats a long one padded to reach a number. Platforms also set their own upper limits and change them, so check the current ones for Instagram and LinkedIn instead of working from a figure someone posted a while ago. Draft the story first, then let the draft decide the count.
That depends on the platform and on how it currently displays carousels, so check its specs before you export. The models here offer several aspect ratios, including square and portrait options, so you can set the ratio when you generate instead of cropping afterward. Keep text and logos away from the edges, and use one size for every slide so the set swipes cleanly.
Keep the on-slide text short, put the exact words in quotation marks in the prompt, and avoid unusual long words where a plain one works. Then read every slide letter by letter. If one line is wrong, regenerate that slide or send it back to an image model as a reference and ask it to change only that line, then compare the result with the original.
Brand colors are easy: name them in the style paragraph, with hex codes if you like. A logo is harder. Image models redraw rather than paste, so the result can differ from your original. Bring your own logo in as a reference image, check it closely, and if it comes out off, add the logo in a design tool afterward. Use only logos and photos you own.
No design tool and no templates are required, but taste still matters. You decide what the story is, which option looks right and whether the type is readable on a phone. A simple rule helps: one idea per slide, large type, plenty of space. If you can write a clear sentence and compare two images, you have what the process needs.
Each generation costs credits, and the cost depends on the model and settings you pick, so a carousel of several slides with a few options each adds up differently from model to model. New accounts get free credits to start, and current plans are listed on the pricing page. Check there rather than relying on any number written here.
Your next carousel starts with a topic and a word cap. Open the Picasso IA toolkit, draft the slides and see what the first cover looks like.
