Shiori — Reading Guide

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.

Imported text and reading positions stay on your device. OCR runs on-device with Apple's Vision framework, and read-aloud uses AVSpeechSynthesizer. No content is sent to a server. AI furigana runs on Apple Intelligence's on-device Foundation Models.

Shiori is a reading aid, not a medical device.
