Thorough spell checking 🕵️‍♀️

Open the Spell Check tab in the right panel. It scans your writing and corrects it in no time. It detects the language automatically, but you can also pick it yourself (Auto / Korean / English / Japanese / ✨ AI check).
For Korean: on desktop, it checks with the meticulous Pusan National University engine (and automatically switches over to the Naver engine if it can't connect); on iPhone/iPad/Android, it checks using the Naver-based engine. (Unfortunately, this isn't supported yet in the web browser version 🥲)
English & Japanese: they use the proven LanguageTool API, working flawlessly on every device, including the web!
✨ AI check: if you have an AI API key (or the desktop agent), the AI proofreads Korean and English together at once, regardless of language. It's a strict teacher that even reads the context.
Fix everything in one go: happy with the results? The toolbar's 'Apply all' button applies every correction it found at once. Prefer to change things by hand? The 🔍 button (Find & Replace) next to the title takes you straight there.
Long pieces get checked in chunks, and the status line shows the progress as it goes — something like "Checking… (3/12)". You can see how far along it is, so just relax and wait.
Run into a slang term or piece of jargon ObsiKO doesn't recognize? Register it as an exception word, and it won't bother flagging it again!

Automatic word-spacing correction 🪄

The PyKoSpacing engine is built right in! Don't worry if spacing gets confusing — on the desktop app (Electron), ObsiKO will nail the word spacing for you like a pro.

An all-in-one Korean dictionary at your fingertips 📖

One panel brings together results from multiple dictionaries! Wiktionary (Korean/English/Japanese/Chinese — you can also turn on Spanish, Hindi, and French in Settings), Wikipedia, Free Dictionary, the SCP Foundation wiki (toggle it in Settings), and even the National Institute of Korean Language's Urimalsaem — all in one place!
Namuwiki is a little different: it has no official API, so definitions can't be pulled in. Instead you get a single 'Open on Namuwiki ↗' button at the top of the results — click it and the article opens in your external browser.
Select a word by dragging over it in your document, and it searches automatically in a flash — or right-click and choose 'Look up in dictionary' for the same friendly result.
Turn what you find straight into material: use the Copy and Insert into note buttons under each dictionary result to drop the definition — along with its source — right in as a pretty callout. Looking up an English word? You can even hear a native speaker's pronunciation with the 🔊 button!
Smooth exploration too: run into an unfamiliar word while reading a definition? Double-click it and it re-searches for that word right away. Click the search box and your recent searches pop right up, and collapsed dictionary sections come with a one-line preview so you can decide at a glance whether to expand them. (There's an expand-all/collapse-all button too!)
Blazing fast, you ask?: results you've already looked up are remembered (cached), so a second lookup is a 0.1-second breeze! And if the internet drops, the offline dictionary has your back. If the network hiccups briefly, you can re-query just that dictionary with the Retry button.
The Urimalsaem dictionary, due to security policy (CORS), is served on desktop, iPhone, iPad, and Android through ObsiKO's native workaround, and on the web through ObsiKO's proxy (obsiko.com). Don't forget to enter your auth key in Settings!

An offline dictionary pack that keeps working with no internet 🎒

Even without Wi-Fi or an auth key, there's a converted Urimalsaem pack ready to go! (It may come bundled by default, or you can import it yourself.)
The first time you install and launch the app, this handy offline pack might install itself automatically — don't be surprised!
Multiple packs at once!: install several dictionary packs simultaneously — say, a Korean pack plus an English pack (importing a pack with the same name replaces the old one with the new one). Each installed pack gets its own section in the dictionary panel.
Handles inflected forms like a pro: search '먹었다' and it points you straight to 먹다; search '사과를' and it points you to 사과. And if it still can't find a match, it suggests similar headwords as chips you can tap.

How much have I written? (status bar stats) 📊

Character count, word count, link count, estimated reading time — all standard! ObsiKO is the only one that even tells you your manuscript page count (원고지 매수). That kind of detail, only here. 😉 → For a closer look at the screen: A Tour of the Screen
