What is 翻翻词卡
在英文网页上划词，AI 解释它在这句里的意思；收进生词本，查过的词下次在别的网页会自己亮起来。翻译免费，语境解释需自己的 AI Key。 翻翻词卡把你每天真实读到的英文，变成你自己的词汇资产。
划词就懂。选中一个词，AI 结合它所在的这句话给出解释——不是词典里那条最常见的义项，而是它在这里到底什么意思。「lock a table for minutes」里的 lock 不是「锁」。
查过的词，下次自己亮起来。打开翻翻模式，生词本里的词会在任何网页上被轻轻标出来；点一下直接看已经保存的释义、原句和例句，不再调用 AI，也不产生新的费用。
收进生词本，带着原句复习。收藏时连同它出现的那句话和网址一起存下来——脱离语境的单词表是背不下来的。复习按间隔重复排期。
也能翻译。悬停加一个键翻译这一段，一个快捷键翻译整页；YouTube、B 站和带字幕轨的视频鼠标移上去就有双语字幕开关，自己画字幕的播放器点一下字幕区域也能翻。译文追加在原文下面，不替换、不打乱排版。
翻译免费，语境解释要你自己的 AI Key。不配 Key 时走谷歌翻译接口：词典义、整页和字幕翻译都能用，只是没有「这句里指什么」。要语境解释，填一个 DeepSeek、Anthropic (Claude)、OpenAI、Gemini 或任何 OpenAI 兼容接口的 Key；按每天查 30 个词算，用 DeepSeek 一个月大约 7–12 元（估算）。
