SwipeStack

For writers who publish long-form work

Turn one finished article into platform-ready carousels.

Import from RSS or paste an article. SwipeStack lays out your exact prose into Instagram carousels, LinkedIn PDFs, Stories, and export packs — without screenshots, Canva fiddling, or AI rewrites.

Your words stay yours. AI only helps with optional captions, hashtags & alt text.

We did not lose our attention all at once. It was taken in increments so small that each felt reasonable, even kind.

From a wall of text to a deck people actually swipe.

Same words, restyled for the feed — never rewritten.

The problem

Your article deserves better than a screenshot thread.

Screenshots, Canva, and AI summarisers all fail serious writing in different ways.

Screenshots crop the thought

Lines cut off, images break, and long arguments become unreadable on a phone.

Canva starts from a blank page

You rebuild what you already wrote, slide by slide, every single time.

AI summarisers flatten your voice

The post may be shorter, but it no longer sounds like you.

Platform rules change the output

Instagram, Stories, and LinkedIn each need a different fit and size.

The verbatim guarantee

What you wrote is what publishes.

Every word, in your order, exactly as you wrote it. SwipeStack lays your prose onto beautiful slides — it never rewrites, summarises, paraphrases, or reorders a single sentence.

Never rewritten

Your sentences are placed, not paraphrased.

Never reordered

You choose what lands on each slide.

Never AI-written

AI only ever drafts optional captions & alt text.

It’s the promise no screenshot tool, Canva template, or AI carousel generator makes — and the reason writers trust SwipeStack with their work.

How it works

Your article. Your words. Social-native layout.

From RSS to carousel in minutes — three steps, no rewriting.

01

Import from RSS

Paste your Substack URL or any RSS feed. We pull in your articles automatically.

02

Auto-flow or highlight

Flow the whole article into slides, or tap text to assign it exactly where you want.

03

Export or publish

Download PNGs, a ZIP or a PDF — or schedule and publish on the Publisher plan.

One source, many outputs

Make the right version for every channel.

Start with one source article. SwipeStack creates target-ready editions for Instagram carousels, Stories, LinkedIn documents, square posts, and export packs — each adapted to the platform, your words untouched.

Manual selection

Highlight text. Tap. It's on the slide.

Single tap selects a paragraph, a second tap cycles to a sentence. Add it to any slide in under three taps.

Platform fit

Know before you post

Platform fit checks, before you publish.

If Instagram only allows 10 slides and your article needs 18, SwipeStack can split it into editions or export a manual upload pack.

FAQ

Questions, answered.

Does SwipeStack rewrite my article?

No. Your words are preserved exactly. AI is only ever used — optionally — for captions, hashtags and alt text, never for your slide or article text.

Can I use this with Substack?

Yes. Paste your Substack URL and we'll find your feed, or add any RSS feed from Beehiiv, Ghost, Medium or WordPress.

Do I need to connect Instagram?

No. You can export images, a ZIP or a PDF and post manually. Direct publishing is an optional Publisher feature.

Can I just download images?

Absolutely. Export ordered PNGs, a ZIP pack, or a LinkedIn-ready PDF on any paid plan.

What happens if my article needs more than 10 slides?

SwipeStack checks platform limits before you post and can split your piece into editions, suggest a denser template, or export a manual upload pack.

Can I use LinkedIn?

Yes — multi-image posts and document/PDF carousels are both supported, with professional captions and alt text.

Can I add footnotes and sources?

Yes. Footnotes, source cards and citation styles are first-class — built for journalists, analysts and researchers.

Can I manage multiple newsletters?

Yes. Add multiple feeds, each with its own default style, CTA and platform targets.

Is there a free plan?

Yes — 2 projects a month with watermarked exports, so you can try the full editor before paying.

Is this a mobile app?

It's a mobile-first web app you can install to your home screen. A native app may follow if it earns its place.

Your article deserves better than cropped screenshots.
