Try the extension right here
This page is full of real Japanese text to play with. Follow the three steps below and you will know everything the extension does.
Looking for the extension…
Step 1
Select one word
Drag over a word with your mouse, or double-click it. A small menu pops up with Dictionary, Add to deck and Strokes.
Sample text 私は毎日、日本語を勉強します。水を飲みます。猫が好きです。
💡 Try 猫 (cat) or 水 (water). Tap “Add to deck” to keep the word.
Step 2
Select a whole sentence
Now select the full line. Choose Sentence in the menu and the extension splits it into words you can tap one by one.
Sample text 学校で日本語を勉強します。この猫は大きいですね。
💡 The meaning stays hidden until you click it, so you can guess first.
Step 3
Watch your words light up
Every word saved in a deck is highlighted on every page you visit. Click a highlight to say whether you remembered it.
Sample text ありがとう。今日は学校で日本語を勉強しました。大きい猫が水を飲んでいます。日本のごはんを食べるのが好きです。
💡 Nothing lit up yet? Save a word in step 1 first, or create the sample deck from the extension welcome screen.
That is the whole loop
Read, save the words you do not know, and the extension brings them back exactly when you are about to forget them. Open the extension to review what you saved today.
