Who it helps
WordHalo for multilingual readers.
WordHalo is built for people who read in more than one language. It detects the language of whatever you highlight — there is no “learning language” to switch — and keeps a separate saved-word library for every language it detects, so French, German, and Japanese vocabulary never mix.
How WordHalo handles many languages at once
- Automatic detection: highlight Spanish at breakfast and Korean at lunch; each selection is identified among 25 languages and explained in your language.
- One setting only: you choose “My language” once. There is no per-site or per-session language switching.
- Separate libraries: every saved word is filed under its detected source language, and duplicates are only prevented within the same language — the French word and its German look-alike can both be saved.
- Filtered practice: flashcards and games can run on one language at a time or across all languages; questions and answer options never mix languages within a question.
- Pronunciation per language: the speaker uses each word's own detected language for audio.
When the source and your language match
If you highlight text that is already in your language, WordHalo skips the redundant translation and opens the Definition tab — useful for native-language words you simply do not know yet.
Limits worth knowing
- Detection covers 25 languages; text in other languages is marked undetermined rather than guessed.
- Very short or ambiguous selections can be detected incorrectly; the surrounding sentence usually resolves it.
- The interface itself is available in 12 of the 25 languages — see supported languages for both lists.
