Global Journey

The Journey Ledger

Fundamentals are the grammar building blocks. Each lesson opens with a short explanation, then a set of practice crystals so you can hear the pattern in real phrases.

• •Every practice set starts with a global cycle crystal.
• •Foundational verbs (是, 有, 去…) are marked with a gold orb.

A crystal is one phrase you can learn. Every card has your native line, the target phrase, Pinyin (for Mandarin), and a tap-to-hear speaker.

• •Red pill: Repeat 7× — hear the phrase seven times in a row.
• •Flip the card for an AI grammar breakdown.
• •Tap the bookmark to save it to My Words.

你好

nǐ hǎo

Hello

🔥0/2

Repeat 7×

Repetition is where phrases stick. Repeat 7× drills one phrase in both voices. Global Cycle plays every crystal in a section back-to-back, hands-free.

• •Walking Raku pauses while a cycle is playing.
• •Use it while commuting or making coffee — it's designed for passive listening.

Anything you save from a crystal, the Custom translator, or Ask Raku lands in My Words. It's your personal deck.

• •My Words has its own global cycle.
• •Tap the red bin on a card to remove it.
