Desktop tools for school teachers · Korea
Switch on the paperwork, then get back to teaching.
Oni School makes desktop apps for Korean middle and high school teachers. Each app takes one slow, repetitive part of school admin, such as class schedules, student record writing or exam proctor rosters, and makes it a few clicks. Everything runs on the teacher's own PC.

The platform
One school, one consistent set of apps
Every Oni app shares the same design system, the same color-coded switch icon and the same local-first approach to data. Teachers learn the pattern once.
Oni Record Oni생기부
Write and check student life records (생활기록부) in one spreadsheet-like grid. AI drafts subject comments, activities and behavior notes from the teacher's own keywords, checks them against the official writing guidelines, and sends approved text to NEIS.
Oni Proctor Oni 감독
Builds fair exam proctor assignments across rooms and periods, so the exams office stops balancing the roster by hand every term.
Oni Time Oni 시간표
The next app on the Oni platform. Details will be shared when development starts.
Oni Enrollment Oni 수강신청
Elective course registration for students, with live seat counts, built on a system already used by around 190 students.
Spotlight · Oni Record
Student records, written and checked in one table
Every December, Korean teachers write hundreds of short, rule-bound comments for each student's official record. Oni Record turns that into four steps.
- WriteType like a spreadsheet. Pick keywords for each student and let AI draft subject, activity and behavior comments.
- AssistKeyword chips give the teacher material for each sentence, so the draft stays in the teacher's own observations.
- CheckEach draft is checked against the official writing guidelines and NEIS byte limits, with before and after shown side by side.
- ApplyApproved text goes straight into the NEIS grid through the Oni browser extension. No Excel upload step.

Student data
Built so student records stay with the teacher
School records are among the most sensitive data a teacher handles. Oni apps are designed around that.
Local-first
Rosters, schedules and records are saved in a database on the teacher's own PC. Oni School does not run a server that stores student records.
Bring your own AI key
Teachers connect their own AI API key. The key is stored on their PC, and requests go from the app directly to the AI provider.
Teacher stays in control
AI only drafts and checks. Nothing reaches NEIS until the teacher selects it and applies it.
Honest scope
Oni Record is a test release. The NEIS extension currently supports cbe.neis.go.kr, with more regions to follow after verification.
About
Made by a teacher, tested in a real school
Oni School is run by a Korean middle school teacher who has spent years building classroom tools: course registration, proctor assignment, record writing and classroom games. Each Oni app started as a tool for one school and was rebuilt so any teacher can install it.
Our aim is simple: give teachers back the hours that school admin takes, without asking them to give up control of their students' data.
