A closer look
Follow the real interface through six parts of a teacher’s workflow. Click any screen to inspect it at full size.
01 / Daily overview
Your calendar, to-dos and attendance share one workspace. Select a date to see its details without losing the month around it.
See school events and personal reminders together.
Keep a checklist next to the day it belongs to.
Open attendance from the selected day.
02 / Class records
Move from your class roster to an individual profile. Keep observations and counseling follow-ups close to the student they concern.
View student details in a structured profile.
Record counseling notes and follow-up actions.
Use the seating view to arrange your classroom.
03 / Attendance
Record an absence, late arrival, early departure or missed class. Review monthly totals and open the underlying record when you need the detail.
Keep attendance categories and supporting-document status together.
Expand a student row to inspect dated records.
Review absence statements in the dedicated tab.
04 / Submissions & lists
Create a collection with more than one document. Check each item per student, then switch to the outstanding list before your next reminder.
Track forms separately, even within the same collection.
Filter completed and pending students.
Copy the pending list or export the collection to Excel.
05 / Lesson progress
Define the units once, then track how far each class has reached. Compare classes without keeping a separate spreadsheet for every group.
Organize a plan by grade and subject.
Keep the ordered lesson units together.
Adjust progress independently for each class.
06 / Desktop widgets
Choose compact views for today, the timetable, lesson progress, notes and the calendar. The Windows app can place them on your desktop.
Choose a widget size to suit your workspace.
Keep quick notes within reach.
Use desktop placement and window pinning in the installed app.
The gallery is shown here. Desktop positioning and pinning require the installed Windows app.
Your data, explained
Oni Class uses local storage and a limited mobile sync scope. “Stored locally” does not mean that every feature works without an account or cloud services.
Detailed student profiles, enrollment history, counseling and observation notes, seating layouts, memos, lesson progress and import history remain in the local record store.
The Windows app stores records in SQLite and protects record payloads with Windows account-based encryption (DPAPI).
Calendar entries and to-dos, attendance, submission lists, timetable information and a minimal class roster are included in the mobile sync scope.
The minimal roster includes student ID, name, class number and class placement. Timetable and roster data are supplied by the PC.
Account and service checks use online services. Make backups through the app; a database file alone should not be treated as a portable, readable backup. NEIS transfer is a separate, teacher-initiated workflow.
Before your first class
Open the release page, review the release notes and select the Windows installer.
Sign in, enter your school and class details, then add or import your roster.
Add a reminder, record attendance or create a document checklist. Build from there.
Yes. Screens are rendered from Oni Class’s original React components and stylesheet files, with fictional classroom data in an isolated preview. Native Windows operations and live cloud sync were not exercised for these images.
This product guide is in English. The application interface shown here is Korean.
No personal AI API key is required for the class-management workflows shown here. Oni Class and Oni Record are different applications with different storage and service requirements.
NEIS integration requires a separate browser extension and a supported school environment. Availability depends on the target NEIS screen and version. Review transferred records in NEIS. This tour does not demonstrate or verify a live NEIS transfer.
