Explica

A Chrome extension that explains what you read, instead of doing the work for you

Explanations in the target language

Highlight any word or sentence and receive meaning, grammar, structure, register and synonyms written in the language being learned, not a finished translation.

Teacher-set difficulty floor

Teachers set a minimum explanation level for a class so students cannot silently switch themselves down to full translation.

Reading assignments with analytics

Assign PDFs and see active reading time, which pages students spent it on, and how many words they looked up per page.

Writing coach, not ghostwriter

Offers vocabulary and sentence patterns instead of paragraphs to copy, and flags large pastes in submitted assignments.
