About Marginalia – Parallel Reader

Marginalia is a reader for books that exist in more than one version: an original and its translations, several editions of a text, or the language versions of a law or a contract. READ SIDE BY SIDE Open the original beside a translation. The pages stay in step as you read: turn one and the other follows to the matching page. Marginalia matches the pages by the words both versions share (names, numbers, quotations), and on the Mac it can also match them by meaning with a free AI model that runs on your own computer. Correct a page by hand and Marginalia remembers it. WRITE IN THE MARGIN Pin a note to the exact word on the page. Choose what it is: a comment, a link, a video, an image, a file, a clipping, or a long exposé that runs over several pages. Reply to notes, tag them, and refer to other pages ("p. 43") with a tap. SELECT, TRANSLATE, CLIP, CITE Select a sentence to translate it…
