Multilingual Text Simplification: How ELI5 AI Works Across 7 Languages

2026-08-02

ELI5 AI supports seven languages: English, Traditional Chinese (zh-HK), Simplified Chinese (zh-CN), Japanese, Korean, Spanish, and French. This makes it one of the few text simplification tools that works across multiple languages and writing systems.

Why multilingual simplification matters

Text simplification is not just an English-language problem. Every language has its own complex vocabulary, bureaucratic conventions, and technical jargon. A Japanese patient needs to understand a medical report in Japanese, not English. A Spanish-speaking citizen needs to understand a government policy in Spanish.

How it works

ELI5 AI detects the input language and generates explanations in the same language at four comprehension levels. The reading levels are adapted to each language's characteristics — for example, Chinese text simplification involves reducing complex characters and idioms, while English simplification focuses on sentence length and vocabulary.

Use cases across languages

A Hong Kong resident can paste a Traditional Chinese legal document and get four levels in zh-HK. A Japanese researcher can simplify an academic paper for a general audience. A French citizen can understand a government regulation. The possibilities are endless.
