Open the app — Broken Hangul Fixer Have you ever opened a file made on a Mac in Windows and found 강물 unravelled into ㄱㅏㅇㅁㅜㄹ? Or received an annotated classical text where the letters sit crooked, like 쥬역언ᄒᆞㅣ? The first is split jamo, the second is Old Hangul assembled wrongly. In both cases nothing is lost — the assembly has simply come apart — so with the right rules it can be put back. This tool does that assembling for you. ...
Open the app — Classical Edition Comparison Anyone who has collated editions knows the routine. Three different editions of the same book, spread open, hunting for the same leaf in each and matching character by character. Open three PDF viewer windows and every time you turn one you have to find and turn the others. Spot a variant character and there’s nowhere to mark it, so you end up noting it in a separate memo. ...
Open the app — Document Batch Generator You need 200 certificates. The form is identical and only the name and number change. Type a name in a word processor, print. Change the name, print. Two hundred times. Mail merge, you say — but not if the form arrived as a PDF or an image. Which is exactly how certificate templates come back from a design studio. This tool lays your PDF or image template down as it is and puts text on top. Write {n} and the number climbs; paste in a table and several values such as name and affiliation change together. The result is one PDF. All 200 pages in a single file, ready to hand to the printer. ...
Open the app — Extract Text from Audio Files You need to turn a meeting recording into text, and there’s no good way to do it. Online services ask you to upload the whole recording. Which means first deciding whether the contents may leave the building at all. With an interview or a counselling session it’s worse. This tool runs the Whisper model right inside your browser. Download the model once and every calculation after that happens on your own machine. The audio never leaves the page. No server upload, no API key, no sign-up. ...
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. ...
