## What is KaChiKa JA | Learn Japanese?

"Learning Japanese Through Life"

On my journey to learn Japanese, I deeply understand the challenge of memorizing words - learning and forgetting, wanting to speak but unable to start.
As a learner who relies on visual memory techniques, I know the power of visualizing abstract concepts.
This experience inspired the idea of "integrating Japanese into life, learning Japanese through life" - this is the original intention behind developing this app.

### 3/5 — 如果可以免费试用就好了

*2026-03-03*

给了三张图片，没有识别出来，就没有免费次数了，存在bug，希望开发者小哥哥可以开放免费时长，一起完善这个app，看视频采访找到这款app的，但是还没有感受到它的魅力就卡住了🤷

**Developer response:** 抱歉，我优化下逻辑，成功后才扣除次数。
你目前如果失败了，可以尝试卸载重装会恢复次数。

### 5/5 — 这么好的软件怎么不火？

*2025-10-04*

哇，太棒了！梦寐以求的软件

### 5/5 — 啦啦啦

*2025-09-12*

看了视频号的探家vlog找过来的 真的很好用！！！加油👏

### 5/5 — 还行

*2025-08-28*

生成的句子有点太简单了，可以弄难一点或者分级吗？然后是有点小贵，希望能搞促销活动或者买断制。

### 5/5 — 超级棒

*2025-08-24*

真的非常好用，尤其是图片识别，真的是超超超超超级好用，每天坚持打卡

### 5/5 — 很棒的应用

*2025-07-31*

如果可以把一些形容词和动词也加入到词汇表里就更好啦

### 5/5 — 推荐

*2025-06-07*

很好的想法跟很好地落地

### 4/5 — 挺好的学日语，但有导入单词功能就更好

*2025-06-04*

挺好用的，如果有导入单词生成单词相关情景的图片，再根据图片分析就更好了，就是像原来功能那样可以看图识词和分析语法。简而言之，如果能反向根据词生成图分析就好了。

### 5/5 — 好用

*2025-05-28*

惊艳到我了。开发这个app的人是人才

### 5/5 — 图文关联才是语言学习的正确方式

*2025-03-14*

生词似乎不支持动词，希望能支持一下
