Graded wordbooks
CET-4, CET-6, TOEFL, IELTS, GRE, Gaokao and Kaoyan for English, plus core vocabulary sets for every other language.
Vocabulary that
actually sticks.
Graded wordbooks, structured courses and an AI tutor that corrects you in context — gathered in one calm app, without streaks shouting at you or a cartoon owl taking hostages.
CoLingua ships structured courses from greetings to real conversation, plus wordbooks tied to the exams people actually sit.
CET-4, CET-6, TOEFL, IELTS, GRE, Gaokao and Kaoyan for English, plus core vocabulary sets for every other language.
Units and lessons that build in order — greetings, introductions, daily life — each entry with IPA and a native-style pronunciation.
A short piece of real material each day, matched to your level, so practice becomes a habit rather than a project.
Ask anything in the target language. The tutor answers, then explains the mistake you just made — hints first, answers second.
Speak a word or a sentence and get scored on individual sounds, not just “try again”.
Write a paragraph, get corrections with reasons, and a short report on what to work on next.
Most language apps are optimised for daily active users. CoLingua is optimised for the day you stop needing it.
Download the Android build, choose a wordbook, and let the daily content do the nagging.
