Introduction
Social carousel studio — your assistant drafts, you approve, you export to the feed.
Casper is a desktop app for Instagram and LinkedIn carousels. Describe the post to your assistant; review every 4:5 screen in Casper; export when the deck is ready. Publishing itself is always manual — you upload it yourself to the social app.
How it works
| Step | What you do |
|---|---|
| 01 — Install Casper | Download for macOS or Windows — or start from the home page. |
| 02 — Open your folder | In Casper, choose Open workspace… and pick where your carousels live on disk. |
| 03 — Brief your assistant | In Cursor, Claude, Codex, or ChatGPT — same folder — describe the post in plain language. |
| 04 — Review in Casper | Preview every screen, track stages on Production, refine until it feels right. |
| 05 — Export and post | PNG or PDF from the toolbar — you upload to the feed yourself. |
Getting started walks through each step.
