About GYLL

What is GYLL?

GYLL — "Yorùbá — Learn. Play. Discover." — is a free, gamified app for learning conversational Yorùbá. Instead of long reading passages, it teaches through short lessons, vocabulary drills, and listening exercises, organized into ten everyday-life units.

It works right in your browser, installs like an app on your phone or desktop (it's a Progressive Web App), and keeps working offline once you've opened it.

What you'll learn

The full course covers ten units — Greetings, Family, Numbers, Food, Body, Home, Shopping, Travel, Work, and Conversation — built from 128 vocabulary words and phrases across 60 lessons.

Each lesson mixes exercise types: flashcards, multiple choice, listening comprehension, pronunciation practice, and image matching, so the same word comes back around in a few different forms rather than a single flat drill.

How GYLL works

You can start learning immediately as a guest — no account, no sign-up. Your XP, streak, hearts, and lesson progress are saved locally on your device from the very first lesson.

If you'd like your progress to follow you across devices, you can create an account at any point (email, or Google sign-in) — nothing is lost in the switch, and nothing about guest mode requires it.

Progress is gamified around XP, a daily streak, "hearts" (a light mistake-budget per lesson), achievements, and unlockable cultural cards that surface bits of Yorùbá food, names, traditions, and music as you go.

A note on our content

GYLL's Yorùbá words, phrases, and cultural notes are compiled from publicly available, cross-referenced sources. All Discover Yorùbá cultural cards have now been checked by a native Yorùbá speaker, and the rest of the course's vocabulary and lessons are reviewed by a native Yorùbá speaker on an ongoing basis as content ships and updates.

Every unit and every Discover Yorùbá card now ships with real recorded audio, read by a native Yorùbá speaker rather than generated.
