### 2/5 — 自带游览器的翻译功能怎么关闭

*2026-07-22*

这是个bug吧，不停的提示每天只有五次免费翻译，关键根本不需要翻译啊，又关不掉。谁知道怎么解决啊？

### 5/5 — 好用的日语学习与阅读软件

*2026-04-17*

希望能添加播放完发音后自动恢复被中断的音乐的功能

### 1/5 — NEEDS AN UPDATE ASAP

*2026-03-23*

I pay for the advanced AI model subscription and all of the sudden it is refusing to provide explanations when I input a question.

### 4/5 — Please remove the trashcan icon.

*2026-03-10*

This is a great app but my only complaint is the placement of the "trashcan" icon on the text box. I strongly suggest removing this icon because there have been several times when I have had to type in long passages and I had mistakenly deleted them because my finger slipped over the trash icon.

### 5/5 — ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️

*2025-07-27*

This is such a great app, I have it on the bottom bar of my screen so it’s always available. Sometimes I don’t know how to parse a certain sentence or I’m not sure what a certain auxiliary means and this app shows the verb with all the auxiliaries after it. It’s not perfect, but no text parser is! I’ve tried a few others and this comes out on top 100%.

One thing I would love to see are the translations of the words under the words themselves, instead of selecting each one to see the meaning. Some of the sentences I input contain many clauses and it’s hard to keep track of the grammar when there’s a lot of unknown words.

### 5/5 — Makes reading rewarding

*2025-01-27*

Takes the slog out of reading at your limit, accelerating learning

Otherwise, it’s painstaking to google translate stuff, get the fruits a, lookup words, and correlate everything. Now you spend more time reading rather than searching

### 5/5 — 嵌入式AI 让学习效率翻倍

*2025-01-27*

无意中发现的宝藏app 让正在学习日语的我 简直像发现宝藏一样！墙裂推荐大家下载⏬

### 4/5 — Really great

*2025-01-11*

Wish there was an option to turn off furigana, but that is my only complaint

### 5/5 — GOLDEN APP

*2024-12-01*

If you love reading Japanese AND UNDERSTANDING what you just read, this app is for you.

### 5/5 — 太实用了

*2024-10-05*

能给作者打钱吗
