Shiori — Reading Guide

Snap a photo of any page, then dial in font, line height, and background until reading feels easy. Pair it with read-aloud, AI furigana, or word focus to suit your style.

Shiori turns your textbooks and printouts into a reading experience tuned to you.

Take a photo of any page (or import PDFs, web pages, or pasted text), then dial in font size, line height, letter spacing, and background color until reading feels easy. Pair it with read-aloud, AI-estimated furigana, or word-by-word focus to fit your own style.

Built for students who want reading to feel less effortful.
