Slow Digest turns the articles you save into a clean, typeset PDF and sends it to your e-reader. You bought a device made for reading, and there's no simple way to get the web's long articles onto it. Slow Digest is that bridge. Save an article, and it arrives on your reader as a quiet, well-set page with no ads and no cookie banners. It works with Kindle, Kobo, reMarkable, Supernote, and Boox. HOW IT WORKS 1. Save an article from Safari or your reading app with the share sheet. 2. Slow Digest reads it, clears the clutter, and typesets it. 3. Your digest lands on your e-reader, ready to read. SUBSCRIBER ARTICLES Share an article from Safari while signed in to the publication, and Slow Digest keeps the full text you can read there. Nothing is unlocked that your own subscription doesn't already show you. BUILT FOR E-INK Justified text with real hyphenation, wide margins, and a cover that lists your reading time. Choose a serif or sans face and the size that suits your screen. Pick your device profile so the page fits, from Kindle and Kobo to reMarkable, Supernote, and Boox. READING, NOT SCROLLING A backlog of saved links tends to sit unread. A digest on the device you already read on gets opened. Slow Digest exists to move your attention off the phone and onto the page. FREE AND PRO The free tier gives you three digests a month, delivered to your reader. Pro removes the limit and adds automatic digests on the days and time you choose, sent to your device on its own. Slow Digest is made by one developer who wanted his own saved articles to get read.
