inline AI
“Built for official HWP documents” — a working assistant that sits on top of your Hangul window
What is inline AI?
inline AI is a Windows AI assistant from Korean company Elements. It opens and edits Hangul (HWP), Excel, Word, and PowerPoint files directly on your computer. It is used where official documents and reports circulate as HWP files.
- 1Edit Hangul (HWP) files directly, with no copy and paste
- 2It works with files staying on your computer
- 3Start free, and upgrade when you run out of credits
What sets it apart
These are the differences we found by running the same material through several tools in our training sessions.
Works directly with Hangul files
There is no pasting into a chat window and copying results back. It opens and edits the document directly inside the Hangul (HWP) program. Formatting stays intact, which matters more than any feature list when you handle documents for submission to public institutions.
Hand over a whole folder
It reads Excel files, PDFs, and images scattered across a folder, not just a single file, and combines them into one deliverable. Copying figures from file to file becomes a single instruction. It suits labor-intensive work such as settlements and performance roll-ups.
It runs on your own computer
You don’t upload files somewhere to work on them. The installed program handles files right where they sit on your machine. That is why organizations that can’t send files outside evaluate it first. You still need to confirm separately what data gets processed.
⚖️ The weaknesses are clear, too
The installer on the official page is for Windows, so Mac users can’t use it out of the box. It runs on credits, so handing over a large folder uses them up quickly. Above all, it is a tool that edits files directly, so if you don’t keep a copy of the original, undoing changes is a hassle.
💡 In plain EnglishIt is less a ghostwriter who takes your materials and writes for you, and more a colleague at the next desk who sits at your seat and edits your files directly.
Public institutions, associations, and the companies that work with them still exchange documents in Hangul (HWP). This tool earns its place wherever pasting into a chatbot keeps breaking the formatting.
Same job, different approach
Friday afternoon, and a Hangul (HWP) performance report for an institution is still due
The old way
- Open several Excel files and check the numbers
- Retype it into the Hangul (HWP) table cell by cell
- Formatting breaks every time you paste, so you fix it again
- The totals don’t add up, so you re-check everything from the start
With inline AI
- Keep a Hangul (HWP) template file open
- Tell it, 'Look at the files in the folder and fill in this table.'
- See what will change on the confirmation screen before fixing
- Have it check the totals, then submit
Common uses
Filling in official documents and report templates
Open your standard Hangul (HWP) template and tell it, 'Fill in the table using the materials in the folder.' The template stays as is, and only the content goes in.
Merging scattered files into one table
Hand over a whole folder mixing Excel files, PDFs, and receipt photos, and have it combine them into one organized Excel file. Tell it to filter out duplicate entries as well.
Pre-submission document check
Keep your finished document open and have the tool check totals and missing items. You still make the final call, but it flags what you may have missed by eye.
Who it’s for
Best for
- ✓People who submit Hangul (HWP) documents to public institutions or associations
- ✓People who pull numbers from multiple files into one table
- ✓Anyone at an organization that can’t upload files to outside services
Better served by other tools
- –People who work only on a Mac or tablet
- –People who mainly want to talk through ideas rather than work on documents
- –People whose main job is image or video production

10-minute quick start
- 1
Download the Windows installer from the official page and install it.
- 2
Log in with the Free plan, then open a Hangul (HWP) document you were working on today.
- 3
Start with small, easy-to-check tasks, such as 'Check whether the totals in this table are correct.'

Copy-and-paste prompts
Replace only the [bracketed] parts, then paste it in.
Look at the files in [folder name] and fill in the [table name] table in the Hangul (HWP) document that is open now. Next to each row, leave a note with the name of the file the data came from. Leave any cell with no value blank and tell me which ones.
Read all the Excel files, PDF invoices, and receipt photos in [folder name] and consolidate them into one Excel file. Use these columns: date, vendor, expense category, amount, source file. Flag any entries that look like duplicates.
Using the Hangul (HWP) official-letter template that is open now, write a draft about [subject]. Use the tone of an official letter sent to an agency, keep the template and fonts as they are, and fill in only the body text.
Check this document before I submit it. In order, verify that the table totals are correct, that the numbers in the body match the numbers in the table, and that no fields are blank, then list only the places that need fixing. Do not fix anything yet.
Open the Hangul files in [folder name] and match the title font and table formatting to [reference file name]. Don’t change the body text; only touch the formatting.
Using it with other tools
Linking two or three tools changes your work more than any single tool does.
From research to submitting official documents
From meeting minutes to performance reports
Before you start
- The installer on the official page is for Windows. If you use a Mac, check compatibility first.
- Running on your computer is not the same as nothing leaving it.
- It is a tool that edits files directly. Always make a copy of the original before giving it instructions.
- It runs on credits, so handing over a large folder all at once drains your limit quickly.
Pricing: personal use and work use

Drawbacks of inline AI
We don’t just list the positives. Here is what fell short when we used it.
- The free 500 credits are just a taste
The Free plan’s 500 monthly credits run out after polishing just a few documents. You hit the limit before you can really try it on your work, so the decision ends up being made on a paid plan.
- Few examples to learn from yet
As a new Korean tool, it still has few hands-on examples or screen videos you can search for and follow. You will need some time to experiment on your own to get a sense of how much you can ask of it.
- Team use requires a large upfront payment
The Team plan starts at KRW 600,000, (≈ US$450) paid once for a year of use. For a few people who just want to try sharing it casually, that is a heavy commitment. There is no easy way to test it month by month.
