InterSub 是 Chrome、Edge 與 Firefox 的瀏覽器擴充功能，在影片播放器中顯示雙語字幕，滑過單字即彈出辭典，並在你觀看時自動建立單字清單。
在播放器內把你正在學的語言字幕與母語字幕上下並排顯示。
游標移到任何字幕單字上，影片會暫停，彈出視窗顯示 AI 產生的釋義與前後文翻譯。
查過的單字連同原始語境存入 Wordbook，讓你的清單來自真正看過的劇情。
若某集沒有你語言的 subtitles，InterSub 會用 AI 即時翻譯，並以第二行顯示。
用真實影片與逐詞字幕學語言
每個詞都有獨立時碼轉錄，唸出瞬間即亮起，上方顯示該句中的意思。
免註冊測驗可估算詞彙量並判定 A1 至 C2 程度，再推薦相應影片。
點擊任一單詞即可查看原形、詞性、頻率、句中意思，以及文法、俚語或慣用語註解。
初學時在所有詞上顯示翻譯，進步後只顯示不認識的詞，或完全關閉。

Parrot is an immersive Spanish learning app that repurposes the short-form video scroll into a language-acquisition engine. Instead of grammar drills and gamified streaks, Parrot feeds you clips of native speakers at roughly your comprehension level, lets you tap any word for an instant translation, and nudges you to say the line back out loud. Saved words feed a personal dictionary that returns through spaced repetition, so what you pick up during a commute actually survives to next week.
