Read-OK

Literature to savor. Science to measure.

Read-OK lets you read aloud public-domain Japanese literature and measure expressive reading on your device. Presence, melody, pacing, dynamics, and finish — five lenses that make your reading visible.

Choose passages from classics (Sōseki, Akutagawa, Dazai, Ōgai, Ichiyō, Kenji, and more). The home screen also surfaces recently popular readings. Audio is deleted after on-device analysis and is never uploaded.

Classic literature stays free to measure. Pasting your own text is a one-time Pro unlock. No ads. No account.
