See what it looks like看一眼它长什么样
Every entry follows the same structure: definition, plain explanation, examples, when to use it, commonly confused with — not an off-the-cuff AI reply.每条词条都是固定结构：定义、通俗解释、案例、适用场景、易混淆 —— 不是一段随便的 AI 输出
Hit any word, and AI writes a structured entry on the spot —遇到任何词，AI 现场写一条结构化词条 —— not a pile of links, but one piece of knowledge that's yours不是给你一堆链接，是给你一条属于你的知识。
No more sifting through ten pages yourself. AI fills a fixed template — definition, plain explanation, examples, when to use it — ready to go.不用翻十个网页自己提炼。AI 按固定模板生成「定义 / 通俗解释 / 案例 / 适用场景」，直接能用。
A general dictionary covers what everyone needs. Lexi keeps the jargon of your industry, the acronyms your boss uses, the concepts in that article you just read.通用词典收大众需要知道的；Lexi 收你行业里的黑话、你老板说的缩写、你读到的那篇文章里的概念。
Open it three months later and it's a map of what you learned. Export to Markdown or JSON — the data lives on your own machine.三个月后打开，它是你这段时间的知识地图。可以导出 Markdown / JSON，数据存在你自己电脑上。
It's free, with a daily free quota (roughly 100 entries). If you use it heavily, add your own API key in Settings and run on your own quota.免费。每天有一定的免费额度（约够建 100 条词条）。如果你用得多，可以在设置里填入自己的 API Key，走你自己的额度。
ChatGPT gives you an answer; close the tab and it's gone. Lexi turns the answer into a structured, searchable, exportable entry that syncs to your phone — an asset, not a conversation.ChatGPT 给你一次答案，关掉就没了。Lexi 把答案变成一条结构化、可检索、可导出、能同步到手机的词条 —— 它是资产，不是对话。
In a SQLite database on your own computer. Only if you turn on sync does it upload, encrypted, to your own sync space.在你自己电脑上的 SQLite 数据库里。开启同步后，才会加密上传到你自己的同步空间。
Not yet — it's in progress. Mobile works today (add the web version to your home screen).暂不支持，在做。手机端现在就能用（网页版加到主屏幕）。
No. We don't read your entries and we don't analyse their content.不会。我们不读取你的词条内容，也不做任何内容分析。
