Carousel;IN
Turn your LinkedIn post into a swipeable carousel that looks like a magazine
Paste the post you already wrote. Out comes a swipeable carousel sized for the LinkedIn feed, ready to upload as a document.
Launch App →Editorial typography that stops the scroll
Big serif headlines, italic accent words, and the strikethrough moment that signals tension. The look that gets shared, not skimmed past.
Your brand, not a template
Pick your accent color, drop in your logo, set your byline. Every carousel reads like yours, not a generic deck.
Smart slide breakdown
Paste the post, get back the right shape for the depth of the idea. Hook, setup, body, takeaway, CTA, all written for you.
Lean the hook your way
Tension, framework, story, contrarian, or let the AI decide. The first slide is what makes someone swipe.
Ready in one click
Hits LinkedIn's native carousel format. Download, upload as a document, post. No design tool detour.
Your keys, your data
No subscription, no account, nothing on our servers. You pay the AI provider directly, pennies per carousel.
How it works
- Paste the LinkedIn post you already wrote. The post stays exactly as you wrote it. The carousel is the visual layer.
- Pick a hook angle, or let the AI decide. Tension, framework, story, contrarian. Default is decide for me.
- Generate. Tweak. Download. Magazine-quality slides, ready in seconds.
- Upload the PDF as a LinkedIn document. LinkedIn renders it as a swipeable carousel in the feed.
Who Carousel;IN is for
- Founders and operators who already write on LinkedIn but skip carousels because making one in a design tool eats half a morning.
- Content marketers and creators who don't want to lay out a carousel slide by slide for every post.
- Builders learning in public with long ideas that don't fit in a single post and deserve to swipe well.
- Anyone tired of generic AI carousel tools with watermarks, paid tiers, and stock-photo backgrounds.
Not for you if: you want auto-posting, scheduling, or analytics dashboards. Carousel;IN is a drafting and design tool. You upload to LinkedIn yourself.
How Carousel;IN is different
There are several ways to make a LinkedIn carousel today. Here's the short version of what makes this one distinct.
Editorial typography baked in
Most carousel tools start from a blank template and lean on stock photos. Carousel;IN starts from the typography that magazines and longform editorials use, so the hook lands before anyone reads the body.
Your brand, not the tool's
Set your accent color, logo, byline, and URL once. Those details stick across every carousel you make. No watermarks, no “made with” footer.
The AI does slide breakdown, you keep the voice
Paste the post you already wrote in your voice. The AI handles the visual structuring, slide roles, and accent words. Your words stay yours.
BYOK, not a subscription
No monthly fee, no seat license, no account. Bring your own Anthropic API key, pay pennies per carousel directly to the provider, and keep your content off anyone else's server.

Frequently asked questions
What is Carousel;IN?
Carousel;IN is a free web app that turns a LinkedIn post into a swipeable PDF carousel with editorial typography. You paste the post you already wrote, the AI breaks it into slides with assigned roles (hook, setup, body, takeaway, CTA, outro), and the app renders each slide in a magazine-quality template. You download the PDF and upload it to LinkedIn as a document, where it shows up as a swipeable carousel in the feed.
How is Carousel;IN different from other AI carousel tools?
Most AI carousel tools are paid SaaS with generic templates, stock photos, and watermarks on free tiers. Carousel;IN is narrower and more focused: editorial typography is the design language, your brand kit lives in localStorage so every carousel is yours, and there is no subscription. You bring your own Anthropic Claude key and the AI handles only the slide breakdown, never the voice.
What can I customize?
Display name, handle or tagline, URL or link to print on the CTA slide, accent color (six presets plus a custom hex picker), and an optional logo that appears as a corner watermark on every slide. Those brand details are saved locally and reused for every carousel. You can also upload an optional hook image that becomes the background of slide 1; that one is a per-carousel asset and clears after each generation, so you upload a fresh one for each post.
Does Carousel;IN post automatically to LinkedIn?
No. Carousel;IN never posts on your behalf. It generates a PDF that you review, edit if needed, and upload to LinkedIn yourself. This is intentional. Auto-posting is against LinkedIn's best practices, and the carousel is meant to complement a post you already chose to write.
Is my data stored on TwoSetAI servers?
No. Carousel;IN stores your API key, brand kit, and last carousel locally in your browser. The post text is sent directly from your browser to the Anthropic Claude API using your own key. The PDF is rendered entirely in the browser. TwoSetAI does not operate a backend for Carousel;IN, so there is no account to sign into and no logs of your content on our side.
How much does Carousel;IN cost?
The Carousel;IN app itself is free. You bring your own Anthropic API key and pay Anthropic directly at their published per-token rates. A typical carousel costs a fraction of a cent. There is no TwoSetAI subscription or paywall.
What models does Carousel;IN support?
Carousel;IN uses Anthropic Claude Sonnet 4.6 by default for the slide breakdown step. Sonnet has the editorial sense for headlines, accent word selection, and structural decisions that lighter models miss.
Who built Carousel;IN?
Angelina Yang, the sole operator of TwoSetAI and a fast.ai fellow. Carousel;IN is part of Angelina's Lab, a collection of free BYOK tools for builders.
