## What is OCAT?

OCAT is a sentence-centered language learning app. Simply enter what you want to say in your native language, and OCAT will show you a natural, idiomatic way to say it in the language you are learning. You can play the pronunciation, view pronunciation guides, save sentences, and build a personal phrase bank rooted in your own life.

Learning sentences beats memorizing words!

The name OCAT comes from the Japanese phrase "教えて (oshiete)," meaning "please teach me."

Collect sentences, train your ears, and practice shadowing:

【Learn sentences】 Want to know how to say something in another language? Enter it in your native language, and AI will quickly provide a natural expression.

【Save sentences】 When you find an expression you want to remember and use again, save it to one of your collections.

【Your personal phrase bank】 Collect sentences that are genuinely connected to your own life and build a spoken-language phrase bank that truly belongs to you.

【Loop playback and train your ears】 Play saved sentences repeatedly in the background so your ears become familiar with sentence patterns, pronunciation, and the feel of the language.

【Natural voices】 OCAT includes very natural-sounding reading voices that help you practice shadowing more effectively while developing good intonation.

【Shadowing and speaking practice】 Imitate each sentence's rhythm, intonation, and pronunciation to move beyond a foreign accent — train your ears to improve listening, and shadow to improve speaking.

Think back to what you just said, ask OCAT, save example sentences, play them repeatedly to train your ears, and then practice speaking through shadowing!

Build a phrase bank that truly belongs to you, and learn to speak naturally in everyday life, just as a child does!

AI assistance in OCAT is limited to language-learning use cases, such as creating natural example sentences, pronunciation practice, and review support.

### 2/5 — 必须充会员且费用很高

*2026-08-04*

rt

### 2/5 — 圈钱圈圈圈

*2026-07-21*

第一，主页上其他界面标明可以自由选择Ai，请问这些Ai是否为套壳ai？有没有安全隐患？
第二，对话模式下的ai为ds4模型，在该模型价格如此低廉的情况下，定价依旧走高。
第三，不支持用户自己的api。标榜所谓的高级功能整体订阅付费，来走你的中转，你是纯纯写作圈不上来这圈了？

**Developer response:** 您好，感谢您认真提出疑问，也想针对您提到的几点逐一说明。

首页提供的是可自由选择的大模型，并非所谓“套壳 AI”。OCAT 通过 API 接入 Gemini、OpenAI 等全球主流大模型，也提供 DeepSeek 等更经济的选择。不同模型的能力、稳定性和调用成本存在差异，用户可以根据需要自行切换。向云端 AI 提交的内容会发送给所选模型以生成回复，具体规则也可以查看我们的隐私政策；建议任何云端 AI 服务都不要输入密码、证件号码等高度敏感信息。

您在对话模式中看到某个价格较低的模型，并不代表整个产品只产生这一项成本。会员包含大模型调用、语音朗读、服务器和持续维护，同时还包含大量面向外语学习专门开发的功能，例如精准日语注音、句子收藏与自定义分类、后台循环播放、播放间隔和语速调节、影子跟读、AI 对话练习、测试模式、睡眠模式、原始对话溯源，以及经过专门调校的语言学习流程。这些功能是通用 AI 聊天应用很难直接提供的，也凝聚了团队长期开发、调试和维护的工作。

目前不支持用户自行填写 API，是因为 OCAT 的功能涉及模型调度、语音、注音、收藏、上下文和学习流程之间的完整协作，并非简单转发请求的中转工具。自行接入不同来源和规格的 API，也会增加兼容性、稳定性和安全维护上的问题。我们会继续评估这一需求，但无法因为暂未提供该功能，就将正常的订阅模式认定为不合理。

软件收费本身是正常的商业行为，就像您正在使用的 iPhone 也需要向苹果公司付费购买。OCAT 没有强制您订阅，也不会在未确认的情况下扣费；觉得功能或价格不合适，完全可以继续使用免费部分或停止使用。会员折算下来平均每天约一元，对于需要长期练习听力和口语的用户，我们认为已经尽量保持了克制和实惠。

OCAT 与纯纯写作由同一团队认真开发，但两款产品的功能和持续成本并不相同。我们每天都在打磨产品、修复问题和增加学习功能，仅仅因为产品收费便给予低分评价，对持续投入开发的团队并不公平。希望您在了解以上情况后，能够基于实际功能和使用体验给予更加公正的评分。

### 4/5 — 前面不要钱，后面听朗读要会员

*2026-07-20*

被一开始体验的骗了

**Developer response:** 您好，您目前并未购买会员，也没有产生任何扣费。OCAT 在首次使用时会开放部分会员功能供体验，体验结束后，朗读等需要持续消耗语音与 AI 服务资源的功能会恢复为会员专属，是否订阅完全由您自行决定。

软件提供收费服务是正常的商业模式，就像日语语言学校收取学费一样，收费本身并不等于“骗人”。OCAT 会员平均每天约 1 元，即可使用 AI 外语对话、日语平假名注音、句子朗读、句子收藏与自定义分类、后台循环播放、语速和播放间隔调节、翻译开关、影子跟读、对话练习、测试模式、睡眠定时，以及从收藏句子返回原始对话场景等功能。对于需要长期练习口语和听力的学习者，我们认为这个价格已经非常实惠。

如果您觉得这些功能不适合自己，可以不购买会员，也不会产生任何费用。我们欢迎对功能和价格提出意见，但将正常收费的会员功能描述为“骗人”，对认真开发和持续维护产品的团队并不公平。感谢您的理解。

### 5/5 — 很好用

*2026-07-16*

很智能 帮助大，一直在用，反应很快

### 4/5 — 很有想法，当还需要进步的app

*2026-05-22, version 8.0.3*

通过句子来学习英语口语这一块想法很好，但是有一些比较陌生或者偏门的单词，可以任意听，写，记以及单独点那个单词的发音就更好了，最好可以整合成一个自己组的单词表，例句可以更加延伸，希望可以更加改进

### 5/5 — 好用

*2026-05-20*

市面上无其他可替代产品，用来语言学习太强了。考虑到ai的token很贵，订阅费用也可以接受，希望用的人多起来，这样子人均费用还有降低的空间。良心软件，千万不要停止运营啊🥲

**Developer response:** 非常感谢您的五星好评和长期支持！您的认可对我们来说非常珍贵，也给了我们继续运营和打磨产品的动力。

OCAT 最新的 9.4.0 版本已经推出，影子跟读、对话学习以及整体使用体验都做了进一步优化，推荐试试 OCAT app 最新版。我们团队每天也在高强度使用 OCAT，不断发现细节问题并持续改进，希望把它做成真正好用、值得长期使用的语言学习工具。

再次感谢您的支持，也感谢您愿意推荐给更多学习语言的朋友！

### 5/5 — 高效率学习语言神器

*2026-05-14*

这个 app 太绝了，不仅可以翻译日常每一句话，看语法，还有很多扩展，最重要是可以收藏下来反复听，用半年，日语水平突飞猛进

**Developer response:** 非常感謝您的五星好評與支持！也很高興這款 App 能夠幫助您提升日語水平。

我們推薦您更新並體驗 9.0 之後的最新版本，其中新增了影子跟讀、AI 對話模式等功能，也提供了許多內建句庫及更多句庫合集可供下載。相信這些新功能會讓您的日語練習更加豐富、高效，希望您也會喜歡！再次感謝您的支持！

### 4/5 — 希望能增加对妙控键盘的适配

*2026-05-03*

回车不是发送居然是换行吗。。。一个翻译软件要换行干什么

**Developer response:** 非常抱歉這個操作方式為您帶來困擾。為了避免使用者原本只是想換行，卻不小心直接送出內容，目前我們支援按住 Shift 或 Command，再按 Enter 來傳送。

不過我們也理解您希望直接按 Enter 就能送出的使用習慣。後續版本中，我們會為此提供一個實驗性選項，開啟後即可直接按 Enter 傳送內容，方便您依照自己的需求選擇。感謝您的建議與支持！

### 5/5 — 名字取得太可爱了🥹言葉遊び大好き

*2026-03-25*

非常好 帮大忙了。大大便利了学日语时使用ai的场景。
有几个希望能做到优化的地方：1. 增加消息的搜索栏。有些消息没有收藏但后续还想再看一下，如果可以通过聊天记录关键词检索到就会方便很多。
2. 语音输入识别文字。
3. 拍照识别文字。
感谢🙏非常喜欢你们做的这个 我会推荐给更多朋友

### 5/5 — 非常好用非常喜欢

*2026-03-24*

我用它来学日语口语 效果非常好 它不仅帮助我学会了很多日常生活中的日语口语句子 而且 还对于 我的 jlpt 考试也很有帮助 我通过它在句子中背语法 效果非常好 非常感谢这个应用 如果可以我愿意给一百💯星
