当你正在阅读

She had read the word a hundred times before, but only now, by the river at dawn, did it truly land:
the water was effervescent , and for a moment the whole current seemed to lift and breathe, each ripple catching the first pale light and breaking it into a thousand small bubbles of gold that rose, trembled, and were gone before she could name them. She read the sentence again, slower this time, mouthing the word to feel its shape, and something about the morning, the cold air, the moving water, the hush over everything, made it stay with her for good.

大家怎么说

“I have probably cried closer to a quarter as many times in a week.”

INSANELY responsive developer!! Will expand on this in the points below, since the features I LOVE tie into how responsive the developer is.

I'm currently a medical student who has started clinical rotations, so it is not only learning a lot of names of conditions, drugs and therapeutics on the fly. All of the drugs have both a brand name and a generic name, and on top of that every professional who uses the electronic medical record to write their notes uses abbreviations for the conditions, drugs and procedures.

Through mostly a variety of brainstorming / whining sessions (on my part):

I mentioned that having Leafy reference MY personal list of words and phrases first when scanning would be incredible, since medical abbreviations can mean other things in other contexts (example: SOB should be “shortness of breath”, not “son of a…” anyway). I think within 5 days the next update included that feature.

I mentioned the new feature was working perfectly, but that it might take me a while to build my vocab list in Leafy, and that there was no easy way to import everything I already had in my Anki deck (Anki is the flashcard app most med students rely on). Now the current version has an Anki integration, so with the settings adjusted, scanned words reference YOUR vocab list and/or YOUR Anki deck first, and if you don't have a card for it YOU CAN ADD IT DIRECTLY TO ANKI FROM WITHIN LEAFY.

The fact that this all happens inside the Leafy popup has made reading other providers' notes on the EMR SO much less stressful. Being able to translate a summary statement like “78M hx HTN, HLD, CAD s/p CABG and multiple PCIs, CKD3 transferred from OSH after 2 episodes of right sided vision loss and imaging demonstrating severe stenosis of L ICA” without leaving the screen is SUCH A GAME CHANGER.

I actually cannot rave enough about this app. The 3rd year of medical school is known to induce a good amount of crying from students, just from the sheer volume of information you need to process while studying and while helping care for patients. I have probably cried closer to a quarter as many times in a week, just from the time and frustration saved having an easier time referencing the terms I need, and it is making it 1000x faster for me to actually learn them.

Automatically saved with its surrounding context.

This is super cool! It is so nice that it quizzes you directly on the text you were reading instead of forcing you to build custom study lists.

Being able to scan a word anywhere on my screen and have it automatically saved with its surrounding context makes reviewing my study materials so much faster. I can already tell this will make tackling heavy reading assignments a lot less tedious.

The cleanest macOS app I have ever used.

Leafy saves the words and the contexts while I look up words reading papers, so I can review them later.

The context save is so smart. That is the key to making the word list alive. The AI responses are really fast and give the meaning in context, so I understand immediately. It is best for building a personal word list and reviewing later.

It solves this gap brilliantly.

I was in search of a solution out of sheer desperation after constantly running into the limits of macOS’s built-in dictionary, which falls short across many third-party and proprietary applications. That is how I found Leafy.

Leafy’s interface is surprisingly intuitive and straightforward. It runs smoothly even on my older Apple M2 chip and clearly receives ongoing care, supported by a developer that resolves issues quickly.

The application integrates seamlessly with my workflow across a variety of apps, including Anki, Obsidian, Apple Books, Arc, and Discord. I especially appreciate that saved words retain their original context, which significantly boosts retention.

As a feature request for future updates, it would be incredible to have the ability to import custom dictionary files so we can rely on local data sources.

释义是哪来的?

AI 会连着你保存时的那句话一起读这个词,所以给的是它在那句话里的意思,不是词典上的每一个义项。LeafyApp 用的是 DeepSeek。AI 有时候会出错,所以原句一直摆在释义旁边。

到底有什么会离开我的 Mac?

只有那个词和它所在的那句话。别的什么都没有。截图只用来把字提取出来,然后就丢掉:不写进硬盘,也不上传。没有账号,所以发出去的东西不挂在任何人名下。

扫描版 PDF 能用吗?

能。你框哪儿 LeafyApp 就对哪儿做文字识别(OCR),所以扫描件、截图、字幕、书页照片,跟能选中的文字一样好使。识别在你自己的 Mac 上跑,不上服务器。

LeafyApp 会一直看着我的屏幕吗?

不会。只在你按快捷键的那一下才看,而且只看你框出来的那块。后台什么都不跑,截图不保存也不上传。

隐私呢?
  • 只在你按快捷键时才看屏幕
  • 截图不保存、不上传
  • 只有单词和它所在那句话会发出去
  • 词库只留在这台 Mac 上
