Why We Do It
The world’s stories deserve to be told in every language.
90%
of books are published in only 8 languages (UNESCO, 2012).
7K+
languages are spoken in the world, but fewer than 500 have an active, sustainable publishing ecosystem (Ethnologue, 2023).
40%
of the world’s languages are endangered (UNESCO, 2016).
40%
of the global population does not have access to education in their own language (UNESCO, 2023).
<8%
of the world’s books are translated into English, whereas 50% of translated books worldwide are translated from English (UNESCO Index Translationum).
Quality and Transparency
Every translation is traceable.
Readers deserve to know how a translation was made. Every Folios translation is published with full provenance metadata — the version of our translation pipeline, the AI model used, the source text, and the date of translation. This is our commitment to openness in an age of AI-generated content.
