What official word lists are available in Tomaru and what is on their cards?

Tomaru includes an official library of over 150 free public word lists covering exams, proficiency levels, and topical vocabulary. Every card features full context, including example sentences, grammar explanations in your explanation language, parts of speech, written pronunciation guides, and high-quality model-generated audio.

Why does Tomaru maintain official word lists?

A spaced repetition algorithm operates neutrally on whatever content it receives. It will schedule a bare word-and-definition card with the exact same mathematical precision as a comprehensive, well-structured entry. However, bare cards rarely equip a learner to use a word in real speech or writing. Because card quality drives learning outcomes just as much as scheduling efficiency, relying on crowdsourced decks of unknown quality often creates gaps in learning.

Tomaru addresses this by maintaining an official, pre-built curriculum library rather than relying on user-contributed content.

What word lists are included in the library?

Tomaru offers a public library containing over 410,000 cards distributed across more than 150 structured word lists. Every list is available to all users at no additional cost.

The catalog is built around standardized framework requirements and real-world language milestones:

• Standardized exams: TOEFL, TOEIC, IELTS, GRE, SAT, and TOPIK.
• CEFR proficiency levels: Structured lists spanning A1 through C2 levels.
• Practical domains: Specialized collections for business contexts and everyday conversation.

Installing an official list adds it to your active study plan, sending its cards directly into your daily FSRS-6 review schedule across iOS, Android, and the web.

What details appear on official cards?

The primary advantage of a centralized library is structural consistency. In crowdsourced decks, card detail varies wildly from entry to entry. Tomaru's official library enforces a rigorous standard across every published list:

Having a grammar note written in your native language changes how you study. Recognizing that a term exists is different from knowing whether it requires a specific preposition or carries a formal register. Centralized curation ensures these critical usage details survive intact across hundreds of thousands of cards.

How does audio work on official cards?

Tomaru generates audio using dedicated neural speech models rather than relying on standard device text-to-speech engines.

For English lists, cards include multiple regional accents and voice options, while Japanese and Korean lists offer an additional voice option, allowing you to train listening comprehension against varied speech patterns.
