Books vs whatever is on screen
Sandbook is built around a library: you import a book or document, and it reads it from where you stopped. Aloud is built around the moment: select text in Mail, Slack or a PDF and press Control-Option-S, or drag a box over text on screen with Control-Option-O.
PDFs and scans
Both read PDFs that have real text. Aloud drops running headers, footers and page numbers and rejoins hyphenated words. Sandbook says a scanned PDF that is only images has nothing to read; Aloud recognises the text on your Mac.
Voices and Macs
Both run Kokoro on the Mac. Sandbook ships more Kokoro voices and languages. Aloud also works on Intel Macs and macOS 14 with Apple voices, and can use cloud voices with your own key.
Who should pick which
Sandbook if you want to listen to whole books and long documents on an Apple silicon Mac, iPhone and iPad at no cost. Aloud if you want any text in any app read on a shortcut, including scans, screenshots and browser articles, with a highlight to follow and audio export.
