Extract Book Lists from Blogs, Newsletters & Substack
Build your digital bookshelf directly from online articles, Substacks, and literary reviews without tedious manual copy-pasting.
The Use Case
Whether you're reading a curated book list on Substack, an annual reading recommendation essay, or a literary magazine review, valuable book recommendations are almost always buried in paragraphs of text. Manually opening separate tabs to look up each book on Amazon or Goodreads creates friction and breaks your reading flow. FoldMarker solves this by scanning full text blocks or article URLs to automatically extract and resolve structured book metadata in the background.
Step-by-Step Instructions
Copy the Text Block or Article URL
Select and copy the text containing the book titles, or simply copy the public webpage URL of the newsletter or blog post.
Paste or Share to FoldMarker
Open FoldMarker and paste your text into the smart scanner input bar, or use the mobile share sheet to send the article directly.
Background Intelligence & Resolution
Click Process. Our AI engine extracts candidate titles and queries catalog databases to resolve official covers, authors, descriptions, and page counts.
Review and Save to Shelf
Review the resolved book cards, refine tags if desired, and add them instantly to your Wishlist or Owned bookshelf.
