## What is Castlingo?

Castlingo 把 油管上最好的英语视频按你感兴趣的话题装进口袋 —— 真实的访谈、演讲、播客，带字字精修的双语字幕。看视频学英语，戴上耳机就能开始。

【六大分类，按兴趣看】
不再被算法乱推。我们每天扫描 YouTube 上最值得看的英语内容，按话题分好类：

- 娱乐 · 文化：Hot Ones / Vogue / Vanity Fair / WIRED
- 两性 · 心理：Matthew Hussey / Jay Shetty / School of Life
- 思想 · 访谈：TED / Andrew Huberman / Tim Ferriss / Diary of a CEO
- 科普 · 科学：Veritasium / Kurzgesagt / 3Blue1Brown
- 创业 · 商业：Y Combinator / Stanford / Acquired
- 科技 · 评测：MKBHD

【字字精修的字幕】
- 中英双语字幕，焦点行高亮，跟视频自动滚动
- 词级 karaoke：每个单词在被说出的瞬间亮起，跟读时机精准
- 不认识的词点一下，加入生词本，例句翻译一应俱全（Pro）
- 锁屏 / 后台继续听音频，进度永不丢

【AI 每日播客 · 5 遍循环法】
真实视频之外，还有为学习设计的 AI 每日播客。基于"可理解输入"假说，同一段对话听 5 遍：
- 英语 3 遍熟悉语感
- 母语翻译 1 遍理解内容
- 英语 1 遍巩固记忆

【词汇小课堂·6 国场景】
美、英、澳等 6 国真实生活场景（银行开户、看医生、点单……）的实用词汇课，配场景插画，点单词即听纯正发音。每一课还能「模拟现场对话」，和虚拟角色一来一往把学到的词用出来。

【句型讲解·227 条地道表达】
每天从播客里提炼母语者张口就来的地道句型：读音跟读、字面意思、什么场景什么情绪该用、3-4 个真实例句，六段式讲透——让你形成语感条件反射，而不是「中译英」。

【练起来，记得牢】
· 词义配对 / 连词成句 / 场景模拟三种小游戏，边玩边练
· 生词自动进词汇本，按遗忘曲线提醒复习
· 连续打卡火苗、成就徽章，坚持有反馈

### 4/5 — 内容不更新了

*2026-09-01*

之前都用得很好，8月30号以后学习播客突然不更新了。更新软件以后也只是多了一个付费的听测功能，听测里的内容也停在30号没有更新。

### 3/5 — 不完善啊，最好能有个反馈渠道，有问题不知道怎么提出和解决

*2026-09-01*

要是有永久会员就好了，感觉有问题不知道怎么反馈

### 1/5 — 设计缺陷

*2026-08-31*

刚开通一年会员在深度使用两周以后 发现收藏的播客不知道从哪里找 这是一个问题 其二 句型讲解有往期回顾可以追溯到四月 但是对应的播客短文往期回顾只有三月的几个 其他的全没有 可以看看评论优化一下吗 为什么支持你们 你们拿出的东西确实瑕疵品啊

### 4/5 — 使用体验

*2026-08-20*

整体的设计还是不错的，付费功能也比较诱人，但订阅渠道似乎不太通畅
可以订阅了，但每日播客（学习）的一些细节值得优化：字幕可以放到上方卡片的位置啊，放到最下边把暂停按钮都挡住了，ui交互设计太草率了

### 1/5 — 怎么自动给我开了个298块钱会员啊

*2026-08-17*

体验一般，还被自动开了个298元会员

### 4/5 — 🤓

*2026-08-02*

挺能提高听力水平的，如果会员可以便宜一点就更好了

### 4/5 — 不能订阅

*2026-07-24*

您好，我想问一下我不能订阅是为什么呀，显示说购买未完成，商品未
加载

### 5/5 — 一手学习资料

*2026-07-04*

非常好用，表达很地道，一手学习资料

**Developer response:** 哇，「一手学习资料」这个评价真的很戳我😄 地道表达这块确实是我们一直在用心打磨的，听到你这么说，感觉值了！希望你越学越顺～

## Frequently asked questions about Castlingo

### What is Castlingo's learning methodology?

Castlingo uses a combination of authentic YouTube videos with detailed bilingual subtitles and AI-generated daily podcasts. The AI podcasts employ a '5-pass listening method' to improve comprehension and language feel, alongside sentence structure explanations and vocabulary games.

### How does Castlingo's subtitle feature work?

Castlingo offers meticulously refined bilingual subtitles that scroll automatically with the video. It includes word-level karaoke highlighting, allowing users to see and practice pronunciation precisely as words are spoken. Users can tap on unknown words to add them to a vocabulary list.

### What are the benefits of the AI Daily Podcast feature in Castlingo?

The AI Daily Podcast is designed for learning based on the 'comprehensible input' hypothesis. It features a 5-pass listening method: three passes in English to familiarize with the language, one in the native language for understanding, and a final English pass for reinforcement. This aims for passive absorption and building language intuition.

### How does Castlingo help with vocabulary building?

Castlingo incorporates vocabulary building through interactive games like 'word matching' and 'sentence construction'. Words learned are added to a personal vocabulary book and are reinforced through spaced repetition, with words automatically entering a review cycle if not practiced for 30 days.

### What content is available in the free version of Castlingo?

The free version of Castlingo provides access to a portion of the content, including 4 passes of the AI daily podcast, one sentence structure explanation per day, and limited vocabulary game practice. Full access to features like word-level karaoke and unlimited vocabulary saving requires a Pro subscription.

### Can I use Castlingo offline?

Yes, Castlingo allows you to continue listening to audio from videos and podcasts even when the screen is locked or the app is in the background, ensuring your progress is saved and you can utilize fragmented time for learning.

### How often is Castlingo updated?

The latest version of Castlingo is 1.3.5, and it was last updated on June 24, 2026. The app is actively maintained, suggesting regular updates to improve features and content.

### What devices does Castlingo support?

Castlingo is currently supported on iPhones. The app is designed for iOS devices, allowing users to learn English on their mobile phones.
