Carousel and deck studio

Carousels and decks, drafted by your assistant. Approved by you.

Bring the article, the report, the notes you already wrote — plus a short profile of how you write. Your assistant turns them into finished screens, 4:5 for Instagram and LinkedIn or 16:9 for a presentation. You review each one in Casper, ask for changes, and export when it is right.

01How it works

You ask. It draws. You decide.

The chat happens in the AI app you already use — ChatGPT, Claude, or your favorite. Point it at the same folder Casper uses, and your assistant drafts the slides there. Casper is where you preview every screen and approve before you export.

Step 01

Open Casper

Open Casper — or try the live demo in your browser today. Your studio for preview and export, not the chat.

Connect02 / 05

Step 02

Share a project folder

Choose a folder for your decks in Casper, then connect the same folder in ChatGPT, Claude, or your favorite assistant — so it can work on your slides there.

Chat03 / 05

Step 03

Brief it in your assistant

In ChatGPT, Claude, or your favorite assistant, describe the deck and your material. It asks what it needs, then drafts the slides in that folder.

02Inside Casper

Your material. Your voice. Designed.

A deck that sounds like you needs more than a topic. Casper works from the content you already wrote and a profile of how you write it — then walks you through the rest.

How it starts

01
Your material
An article, a report, meeting notes, a PDF. The deck follows it.
02
Your voice
Describe how you write once. Every deck from then on sounds like you.
03
Your answers
How long, which format, what tone. Your assistant asks — you pick.

5 screens

Real screens exported from one deck — including the infographic, drawn for this post. Nothing here is a mockup.

Pick a look, or make it yours

Any of 30 built-in themes applies to the whole deck — swap one in and type, color, and texture follow on every screen. Build your own palette and fonts; Casper saves it to your project and lists it in your theme picker next to the built-ins.

Beyond the look

Layouts, infographics, and format

Themes set type and color. Slide layouts are the page skeletons — cover, timeline, quote. Infographics are separate AI images when a screen needs a diagram or metaphor. Formats set the export canvas.

85
Slide layouts
Composition patterns — cover, comparison, timeline, stat, quote, closing.
39
Infographic layouts
Structure of the image — how information is arranged (funnel, timeline, metaphor).
56
Infographic styles
Look of the image — palette, texture, illustration style. Pick one with a layout.
4:5 · 16:9
Formats
Feed carousel or presentation deck. Switch the canvas without rebuilding.

Infographics are generated images, not slide layouts. Your assistant must support image generation — for example ChatGPT or Antigravity CLI. Text-only assistants can still compose the deck; they just cannot draw these visuals.

03live demo

Try the real thing, right here

This is Casper itself, running with a real workspace — open a deck and page through it. This is where you approve every screen before exporting.

Open demo fullscreen

Casper is a desktop app — this demo is best on a computer. On a phone you can still browse, but expect a tight fit.

04Briefing

Just say what you want, like you would to a person.

Paste your text and describe the deck you need. Missing something — how many screens, which format, what tone? Casper asks you instead of guessing. Then it writes and lays out every screen.

For example

“Turn the launch notes into a 7-screen Instagram carousel, waitlist CTA at the end”

Type it however you like. There is no special syntax to learn.

A fair question

Why Casper exists

You

Why would I pay for Casper if I already have ChatGPT?

Casper

ChatGPT is the conversation. Casper is the studio.

You describe the deck in plain language — your assistant writes the slide files in a shared folder. Casper is where you open that folder, preview every screen, swap themes, pick layouts, and export when it looks right.

It also ships the agent guides and catalogs — themes, compositions, infographics — so any assistant that can work on local files can build polished carousels and presentation decks without you touching code.

You are not buying another chat subscription. You are buying the place where drafts become finished work.

Works with

No new subscription. Casper works with the AI you already pay for.

ChatGPT, Claude, Cursor, Codex, Antigravity, OpenCode, Windsurf, Zed — and any app that can edit files in your project folder.
