Open the app — Korean Studies Toolkit (Chrome Web Store)
What do you do when an unfamiliar word appears in a classical text?
Open a new tab, type the dictionary address, retype the word, then find your way back.
A date shows up, so you open another tab.
Ten tabs later you have lost the line you were reading.
Korean Studies Toolkit removes that round trip.
It is a Chrome extension that docks three tools to the right of your browser: the Korean Studies Web Dictionary, the East Asian Chronology and the Unicode Hanja IME.
Your page stays where it is; you look things up beside it.
How to Use
Install and open
Install 한국학 공구서 (Korean Studies Toolkit) from the Chrome Web Store.
An icon appears next to the address bar; clicking it opens the panel on the right.
It uses Chrome’s side panel, so it sits alongside your tab rather than covering it — you can read and look up at the same time.
Three tools as tabs
Three tabs run across the top of the panel.
| Tab | What it does |
|---|---|
| 한국학 웹 사전 | Look a word up across twenty-odd dictionaries |
| 동양연표 | Convert era names, cycle years and temple names to Western years |
| 한자입력기 | Enter hanja by radical, without knowing the reading |
Each is the same site you would use on the web, just opened with its header hidden, since the panel is narrow.
They work exactly as they do on the web, so see each guide for the details.
Right-click to search the dictionary
Select a word on the page you are reading and right-click; the menu offers:
한국학 웹사전에서 "○○○" 검색
Choosing it opens the panel with that word already looked up. No retyping.
This menu item is off until you turn it on — see Turning the features on below.
Select text to check the chronology
Drag-select something that looks like a year or an era name and a small blue 韓 icon appears beside it.
Click the icon and you get the selected text with a [동양연표에서 보기] button; press it and the panel opens on that year.
When you hit a date like 숭정 병자, you can confirm it without lifting your hand.
This feature is also off by default.
Turning the features on
Both the right-click item and the drag icon must be enabled by you.
- Right-click the extension icon → [Options]
- Tick what you want
| Setting | When on |
|---|---|
| Drag tooltip on web pages | Selecting text raises the 韓 icon |
| Add “search the dictionary” to the right-click menu | The context menu gains the entry |
The first time you enable either, the browser asks for permission to access web pages — the icon cannot appear on a page without it.
If you only want the side panel, leaving both off is perfectly fine.
Good to Know
Why they aren’t on from the start
Both features require the extension to be able to step into every page you view — it has to know you selected something before it can show an icon.
That is not a light thing to ask for.
So a plain install touches no page at all, and permission is requested only when you decide you want it.
Turn it off in Options and the extension withdraws again.
What is stored, and what is not
The extension collects no personal data. There is no advertising, analytics or tracking code in it.
Only two things are kept on your machine.
- Your on/off settings — nothing but which features you chose. With Chrome sync enabled they may follow you to your own other devices, but they never reach the developer.
- A one-shot search term — when you look something up by right-click or drag, the panel may not be open yet, so the value is held briefly. It is deleted the moment the panel takes it, and nothing survives closing the browser.
The content of the page you were reading, and your browsing history, are never sent anywhere.
The sites open as they are
The panel simply loads each site — these are not separate apps but the very screens you use on the web.
So as the sites improve, the extension improves with them; there is nothing for you to update.
The flip side is that it needs an internet connection.
