Visual flashcards, spaced repetition, and AI conversation practice across 25 languages. Build vocabulary that actually sticks.
Words that actually stick.
Most language apps are built around streaks, pressure, and guilt. Lengio isn't. It's a calm, beautifully designed visual vocabulary app that works with the way your brain actually remembers — through images, not endless text drills.
LEARN THE WAY THAT WORKS FOR YOU
Lessons
Follow a guided path that builds naturally from the ground up, with mini-exercises after every concept to lock in what you've learned.
Word Categories
Browse thousands of words organised by topic across 25 languages. Words live across multiple categories so you encounter them in context — the way real fluency is actually built.
Quizzes & Flashcards
Spaced repetition built right in, so you review each word at exactly the moment you'd otherwise forget it. No wasted time, no drilling words you already know cold.
AI Speech Partner
Hold the mic and have a real, free-form conversation with an AI tutor in your target language. Gentle, contextual pronunciation feedback as you speak — like having a patient language partner available any time.
221,000+ WORDS. 25 LANGUAGES.
From Arabic to Ukrainian, from Japanese to Portuguese — Lengio covers 25 languages with over 221,000 words, every one paired with an image to anchor it in visual memory. Because a word tied to a picture is a word you actually keep.
MAKE IT YOURS
Replace any stock image with a photo from your own camera roll. Your memories, your associations, your language. The more personal the image, the deeper the word sticks.
FREE & PLUS
Lengio is free to download. Core lessons, word browsing, flashcards, and daily reviews are included at no cost.
