Technology, layer by layer.

From software to AI, from games to semiconductors: each one a layer. We built the first in education; TeknOkul and Kırmızı Kalem run in schools today.

Running on the orange layer.

Two brands, five platforms. Each with its own identity; the same team and infrastructure behind both.

school platform

TeknOkul

School communication and management platform

Announcements, messages, attendance and reports in one place for administrators, teachers and parents. Teachers’ numbers stay private; AI reports never reach parents without the teacher’s approval.

teacher app

Kırmızı Kalem

The teacher’s pocket assistant

Reads written exams with AI; the teacher approves every score. Camera-based optical mark reading, item-level analysis, 4,000+ official learning outcomes.

Why orange? Answer sheets are printed in orange or red “dropout” ink: the reader ignores it and sees only the pencil mark.
