FAQ



What is Kotoba Boost - Japanese Vocabulary?

Kotoba Boost - Japanese Vocabulary is the result of years of learning Japanese and developing Android applications. The members of Lusil are always trying to think of methods and tools to make language learning fun and build our japanese skills.

The idea of this tool is to take the most common words of the subject and help you learn in a quiz type format. Subject will generally be topics that interest you so knowledge can be immediately applied. Topics will be things like Manga, Anime, Songs, Geography, Educational Material and basically anything we might come across.


How much does it cost?

We are currently in the 'Browser Beta'. At this point you are one of the first users to use the tool and will be offered all decks for free. You may experience advertisements in some cases to help fund development. At some point when popularity grows we may switch to a purchase based model but early adopters like yourself will keep everything you get in this early stage.


Where is the mobile app?

Given our past experience with Android applications, there is already work being done for mobile applications but we are using this time to get our services and database correct before giving it a mobile stage.


How do I use it?

At this time the tool is in 'Browser Beta' and thus you should use your computer or mobile device's browser to interact with your account.


How does this level and unlock system work?

When you add a deck you start off as 'Unranked' and your 'Hiragana Only' and 'Kanji Only' options disabled. Kotoba's goal is to try and break any muscle memory you might have to use combinations of Hiragana & Kanji to identify the proper answer.

Therefore, 'Hiragana Only' and 'Kanji Only' options are seen as more difficult than seeing them both together. Answer options will be similar to what you may have seen on a JLPT test.

Read the following to understand the progresion you sould take. Once you have unlocked an option it will always be available to you no matter what happens to your deck level after that.

BRONZE
Achieve bronze by maintaining a good accuracy for all the words of your deck. If you achieve bronze it will unlock the 'Hiragana Only' option in your deck settings. You will need this to reach silver status.
SILVER
Achieve silver by maintaining a good accuracy for all the words of your deck in 'Hiragana Only' mode in your deck settings. When you achieve silver, it will unlock the 'Kanji Only' option in your deck settings. You will need this to reach gold status.
GOLD
Achieve gold by maintaining a good accuracy for all the words of your deck in 'Kanji Only' mode in your deck settings. This is the highest status achievement.

What data do you collect?

You keep saying we. I heard Lusil is just one person?

You heard correct but it's always fun to pretend.
