Open the app — Hanja Normalization Have you ever searched a Hanja document and failed to find a character that is clearly there? It looks like the very same 樂 to your eyes, but the search finds nothing. Copying and pasting it doesn’t help either. The cause is that the same-looking Hanja has several Unicode codes. One character to a human, different characters to a computer. This tool unifies those scattered codes into one standard code. ...
Open the app — HWP Image Detector Sometimes you have to check every photograph across dozens of reports. Clearing copyright, building a list of plates, auditing who inserted which figure. Your only option is opening each file and scrolling through it. And when you find a picture you still have to read around it to remember what it was. This tool takes a whole folder and sweeps every HWP/HWPX file inside. For each document it shows the embedded images along with the sentences before and after where that image sits. It puts the context a picture alone can’t give you right next to it. ...
Open the app — Image Merger Sometimes you need ten covers that share one background and differ only in the title. Series covers, lecture material thumbnails, that sort of thing. Opening Photoshop feels heavy, and doing it in PowerPoint leaves the text subtly misaligned every time. You end up nudging coordinates by hand anyway. This tool lays text and images over a background and exports a single PNG. Coordinates can be typed in as numbers, so even ten covers stay perfectly aligned. You can also save the whole working state and load it back later. ...
Open the app — Index Extractor Once you finish tagging a manuscript, the next problem arrives. “So how many personal names are in this book, exactly?” Have you ever counted tags by eye to build that list? Honestly, half of index work is making this list. This tool pulls out only what sits inside your chosen symbols and turns it into a list. Place names wrapped in 【 】, index terms wrapped in <index>, words emphasized with **. Even if the same thing appears a hundred times it stays once in the list, and you can see how many times it appeared. ...
Open the app — Index Tagger Have you ever tagged every personal and place name in a translation manuscript? Find 慶州, change it to <place>慶州</place>, find the next 慶州, change it again. Using “Replace All” in a word processor sounds fine until you have a hundred index terms — that’s a hundred rounds. And sometimes you replace a spot that was already tagged, ending up with <place><place>慶州</place></place>. So I made this. Write the list of replacements once as a table, and it sweeps through the whole manuscript and tags everything at once. Put translated words instead of index terms and you can use it as a simple machine translator. ...
Open the app — Live Q&A The talk ends, someone asks “any questions?”, and the hall goes quiet. Raising your hand feels like a commitment, and if the person ahead of you asks a long one, the question you had disappears. Even when you work up the nerve, you wonder whether anyone else cares. This tool lets the audience post questions from their phones and vote on each other’s. Whatever many people want to know rises to the top, so the presenter can start there. Questions can be anonymous, which helps in rooms where raising a hand is hard. ...
Open the app — PDF Border Cleaner Lay a book face down on a copier and everything around it comes out pitch black. The lid can’t close, so the empty space gets photographed along with the page. Material from libraries usually arrives in exactly this state. On screen you shrug it off, but printing is another matter. Filling in those black borders drains toner alarmingly fast, and the paper comes out damp. Print one 100-page document and you start resenting the cost of toner. ...
Open the app — PDF Left-Right Splitter Open a scanned classical text from a library and more often than not it was photographed with the book lying open. Two pages on one sheet. On paper that feels natural, but on a screen or a tablet the characters end up half size. The page numbers are half the real count too, so every citation needs arithmetic. This tool cuts such PDFs down the middle and separates them into single pages. It sounds simple, but in practice plenty of things get in the way. The cover is a single sheet yet gets sliced in half, vertically written books must be read right to left, and characters near the binding get cut off. Each of those has its own setting here. ...
Open the app — PDF Page Editor Sometimes you receive a 300-page collection when all you need is three pages. Other times you want to pull pieces from several files and bind them into one. Typing page numbers like 12-15, 47, 88-92 invites mistakes. Numbers alone don’t tell you what is actually on those pages. So this was built as a way to cut while looking. You drop dividers onto a horizontal bar and toggle green (keep) and red (remove). Up to five files can be loaded at once and bound into a single merged.pdf. ...
Open the app — PDF Page Reverser Have you ever scanned a classical Chinese book? A right-bound volume reads from right to left, so feeding it into the scanner in order gives you a file that comes out backwards. The last leaf ends up as page 1. The same thing happens when a sheet feeder pulls pages from the back. The scan itself is fine — only the order is flipped — so there’s no reason to scan it again. ...
