How the analyzer breaks down a Japanese sentence

Take 雨が降りそうですね。 The analyzer splits it into 雨 (ame, "rain", a noun), が (ga, the subject marker), 降り (furi, the stem of the verb 降る "to fall"), そう (sou, "it looks like"), です (desu, the polite copula), and ね (ne, a sentence-ending particle that seeks agreement). Together that is "It looks like it is going to rain, doesn't it?"

Seeing each piece, instead of only the translation, is what turns a sentence you can read into grammar you can actually reuse. For every sentence you get the word-by-word breakdown, the particles, verb forms, sentence structure, formality, tense, furigana, and a plain explanation.

Mistakes the analyzer helps you see

は vs が: は marks the topic (what the sentence is about), が marks the subject (who or what does the action). The analyzer labels each so you can tell them apart.
を vs が on verbs: it shows which noun is the object and which is the subject.
Politeness: it detects whether the sentence is casual, polite, or formal from the verb endings.
Dropped subjects: Japanese often omits the subject, and the explanation makes the implied meaning clear.

Cannot read the sentence yet?

The analyzer explains what a sentence means. If the problem is the kanji rather than the grammar, the kanji to hiragana converter puts furigana over it first, or gives you the whole thing in hiragana or romaji.
