Made for the end-of-term record season
Type as you would in Google Sheets, pick your material from keyword chips, let AI write the draft, check it against the official writing guidelines, then apply it to NEIS.

AI drafts for subject comments, behavior notes and activities.
Keyword chips supply the material for each sentence.
Before and after, against the writing guidelines.
Batch entry into NEIS.
A closer look
Follow the real interface through five parts of the job. Click any screen to inspect it at full size. NEIS is Korea’s national school information system.
01 / The screen
Sheets run along the top, students run down the table, and the right panel changes with the task. Nothing moves to a separate window while you work.
Sheet tabsOne tab per class and subject.
ToolbarUndo, row and column editing, find, import and export, text size and zoom.
Editing tableArrow-key movement, copy and paste, and a NEIS byte count in each cell.
Write · Check · AssistChoose 세특, 행특, 자율 or 기타 (club and career).
Start generatingSelect students and draft them in one run. The NEIS apply button sits just below.
02 / Write
Pick what you are writing and the input panel and the AI’s writing rules change to fit it. The steps stay the same: enter material, set a length, select students.
AI writing rules. The subject teacher’s point of view, in one connected paragraph. Wording that implies one lesson continued from another is avoided, and an empty activity is never invented.
AI writing rules. The homeroom teacher’s point of view, centered on current positive change. A weakness is written with the effort to improve, and the note closes with one sentence on the student’s potential.
(YYYY.MM.DD.) form.AI writing rules. One paragraph that connects what the activity meant with how the student grew. Activity names are written without quotation marks, and opening phrases are varied from student to student.
Club and career activity sheets have their own writing and checking rules, under 기타. They cannot be applied to NEIS yet, so the generated text is copied by hand.
03 / Assist
There is no need to start each sentence from a blank cell. Keyword chips organized by subject and item go into the selected cell, and the AI writes from those keywords.
The chips change with the areaSubject comments are grouped by subject. Behavior notes are grouped by personality, peer relations, class attitude, school life and self-management.
Open a chip to go deeperOpening a group such as “active and sociable” shows more specific keywords like “lively” and “outgoing”. Either level can be chosen.
Straight into the cellChosen keywords are listed under “keywords in this cell”. Remove one with ×, or edit the cell by hand. The same keyword is entered only once.
Search, collapse, cautionsKeyword search, collapse all, and a list of writing cautions for each area come with the panel.
The keywords you choose are what the AI uses to interpret and write each sentence. The keyword lists are a first draft and have not yet been reviewed in schools.
04 / Check
The original is left as it is. Oni Record makes a check sheet with the text before, the text after and the reason, so nothing is overwritten until you decide.
Columns for original, before, after and reason are created.
Each student is marked fixed or unchanged.
Only fixed items are written back to the original cell.
Review the reason for each student and choose what to apply to the original.
If nothing needs fixing, the original is kept and marked 수정사항 없음 (no changes).
A result that was shortened too much keeps the original and raises a warning.
Write your own criteria under “additional check items” and they are checked as well.
The teacher makes the final decision on anything the AI checks. Read the reasons before applying.
05 / Apply to NEIS
No copying and pasting student by student. The app matches its text to NEIS by class, number and name and enters it in a batch through the browser extension.
Link the Chrome extension to the open NEIS tab.
School year, grade and class, and the type of record.
Class, number and name, entered in one batch.
After saving, the result is compared with the app’s text.
Subject comments, autonomous activities and behavior notes are supported. Club and career records are not yet.
An existing record that differs from the selected text is replaced. An empty text is not entered.
The student roster can also be read from NEIS into a new sheet.
If NEIS screens change, some steps may behave differently. Always check the result before and after applying. The extension currently supports cbe.neis.go.kr, with more regions to follow after verification.
Before you start
Writing and checking call the AI once per student, so running a whole class sends the calls one after another. On the free tier, request limits can make a batch stop or slow down partway through.
Editing the table, entering Assist chips, and importing or exporting CSV and Excel all work. AI writing and checking do not.
With a key that has billing connected, a whole class can be written and checked without interruption. Usage is billed to the teacher’s own Google account.
The key is issued in Google AI Studio and entered in the app’s settings. Pricing and limits follow Google’s policy and can change, so check them when you get the key.
Your data, explained
Student records are sensitive, so the app is explicit about where they go. Reviewed against the app source on 9 October 2026.
Writing sheets, student cell contents, generated text, preferences and prompt templates are saved in store.json in the Windows user profile. The separate check window uses store-check.json.
The reviewed source does not sync these sheets to an Oni account cloud. These work files are not encrypted by the app.
Generation and checking send task prompts and the selected work content to Google Gemini, directly from the desktop app, using the teacher’s own API key.
Local file storage does not mean that AI processing stays offline. Handle personal information such as real names following your school’s guidance.
The app encrypts the saved key with Electron safeStorage (Windows DPAPI) when it is available.
The current implementation falls back to plaintext key storage when OS encryption is unavailable.
Nothing is entered in NEIS until the teacher opens the apply dialog and confirms.
The extension works only on the NEIS tab already open in the browser.
Before your first class
Open the release page and run the installer. New versions arrive through the built-in updater.
Issue a key in Google AI Studio and paste it into the app’s settings. A paid-tier key is recommended.
Bring in a roster from CSV, Excel, Google Sheets or NEIS, write a few students, check them, then apply.
