Postbook sends what you want to read to your Kindle, as a proper book.
Share a post, a whole thread or a web article from any app and choose Postbook. Posts from X, Bluesky, Mastodon and Threads all work, and so do articles from Chrome. About a minute later it's on your Kindle as its own book, with its title, its author and a cover, ready to read calmly, away from notifications and the endless feed.
Or paste a link straight into Postbook. Copy one anywhere, open the app, and it shows you what the link is before you make it a book.
ONE SHARE, ONE BOOK
• Threads arrive whole, from the first post to the last, so you never lose your place.
• Replies come with the post they answer, and quoted posts appear as block quotes.
• Long-form articles keep their headings, images, lists and code.
• Each book is titled after the post or article, so your library stays easy to browse.
• A page that won't let apps read it, such as a LinkedIn post or a site behind a robot check: save it in Chrome and share it from Downloads, and Postbook reads the saved copy.
MADE FOR READING
• A cover on every book, drawn by AI from its title and opening lines if you choose, or a clean one with its title and author.
• Optional summaries and critiques for long reads, and the discussion: top comments with a short summary.
• Links in a post can bring their article along.
• Your library in the app shows each book on its way, then with its cover.
SIMPLE TO SET UP
• No sign-up form and no password: enter your Kindle's email address, approve Postbook on Amazon (the app shows you where), and a welcome book arrives to prove it works.
• Use it on your other devices too: Postbook for iPhone and Mac signs in with a one-time code.
• Nothing to install on the Kindle. Books arrive through Amazon's Send to Kindle email.
