Bilingual reading

Bistory

Read the classics in two languages at once. Bistory pairs public-domain books with translations, aligned sentence by sentence, so you can read in the language you are learning with your own language one tap away.

Side by side

Original text and translation are aligned at the sentence and paragraph level for comfortable parallel reading on your phone.

Many languages

Starting with English, Chinese, French and Spanish, with more languages planned.

Public-domain library

Books come from public-domain sources. Where no public-domain translation exists, we prepare one with the help of AI and careful review.

AI narration

Optional sentence-synced audio narration, generated with text-to-speech, follows along as you read.

Platforms

Bistory is coming to iOS, Android and the web. Availability and pricing may vary by region.
