Stratagem Systems School K12
AI scores homework done on paper. It does the work that takes hours by hand, and you see every class as it happens.
The school and students on the screens are examples; the AI results are real. Narrated in Turkish, with English captions.
Teachers do not read the papers one by one: the AI scores every question and prepares a similar question for every mistake; leadership sees at once who has not handed in.
For middle school: grades 5 to 8 · maths, Turkish and science · LGS tracking

At 4 minutes a page by hand, reading each student’s 3 pages of homework a week in a middle school of 300 students takes 60 hours a week. Work it out for your school (in Turkish)
What the AI does in your place
The times below are not measured; they are estimates, and each one’s assumption is in the same sentence. We count 18 students to a class: according to the OECD, private middle schools in Türkiye have 18 students in a class on average (2023/24).
Reads and scores homework, and explains each mistake
- How long it would take by hand
- At 4 minutes a page, reading by hand a one-page assignment of an 18-student class takes 72 minutes.
Prepares a similar question for every mistake
- How long it would take by hand
- At 10 minutes a similar question, an assignment on which the class missed 3 questions comes to 30 more minutes by hand.
Checks the solution to the similar question
- How long it would take by hand
- If checking a solution by hand takes 1 minute, every similar question comes to 18 minutes in an 18-student class.
Prepares the solution video
- How long it would take by hand
- If recording and uploading a solution video by hand takes 20 minutes, 4 videos a week come to 80 minutes.
Reads quiz papers and matches the names
- How long it would take by hand
- At 3 minutes a paper, an 18-student class’s quiz comes to 54 minutes by hand.
Reads the marks on mock-exam booklets without an optical form
- How long it would take by hand
- At 2 minutes a student, one mock exam of an 18-student class comes to 36 minutes.
Prepares the Etüt lesson
- How long it would take by hand
- For a lesson that would take 2 hours by hand, previewing and correcting it is left to the teacher, which we count as 20 minutes.
These are done not by the AI but by the system itself and an app on the computer:
Splits a question book into questions
- How long it would take by hand
- At 1 minute a question, splitting by hand the 64 questions of the 16-page booklet we wrote takes 64 minutes.
Sends reminders to parents and students
- How long it would take by hand
- If writing to a parent takes 2 minutes, 10 students with missing homework come to 20 minutes.
Prepares the parent report and the weekly summary
- How long it would take by hand
- If preparing a student’s monthly report by hand takes 10 minutes, an 18-student class’s reports come to 180 minutes.
Works out the school’s week
- How long it would take by hand
- At 5 minutes a class, leadership asking the teachers one by one how the week stands takes 80 minutes in a 16-class school.
Teachers do not read the papers one by one; they look at the answers the AI is unsure of and the decisions students ask about. The new work for each assignment is the answer key.
What it saves
The figures below are how long the same work would take by hand; they are estimates, not measurements, and each one’s assumption is in the same sentence.
How much time marking takes today
- Full-time middle-school teachers in Türkiye say they spend 2.7 hours a week on average on all their marking (OECD TALIS 2024).
- In Türkiye, 48% of middle-school teachers name too much administrative work, and 44% too much marking, as an important source of stress (OECD TALIS 2024).
An example: a middle school of 300 students
Take a middle school with 75 students in each grade, 300 in all. At an average of 18 students a class (the OECD’s average for private middle schools in Türkiye, 2023/24), the school has 16 classes. If every class gets 3 one-page assignments in each of 36 weeks, the AI reads 32,400 pages in a school year.
At 4 minutes a page by hand, that is 60 hours of work a week.
Taking off, to be cautious, 1 minute a page for the answers the teacher still looks at and 5 minutes a class for each assignment’s answer key, the work the AI does for the school is 41 hours a week, 164 hours a month and 1,476 hours a school year. If your teachers do not do this work today, these hours are not time saved but work added to your school: every paper is read question by question, and every mistake gets a similar question.
Counting 10 minutes a similar question, 10 minutes a monthly report and 20 minutes a video, and adding the similar questions, quizzes, mock-exam booklets, parent reminders, monthly parent reports and 4 solution videos a week, this work comes to 82 hours a week, 2,960 hours a school year.
Work it out with your school’s figures
You enter your number of students, your homework a week and your quizzes and mock exams; you can change the default times too.
Open the calculator (in Turkish)The teacher’s time with the product
- In this example, with 9 teachers, reading the homework question by question by hand would take 6.7 hours a week per teacher. A school at the TALIS average has no time to read this much homework question by question.
- With the product, what is left to the teacher, at 1 minute a page and 5 minutes a key, is 2.1 hours a week per teacher.
- How long this really takes has not been measured yet. To be cautious, we allowed 1 minute for every page. We measure it with your teachers in the pilot.
What leadership sees
You see who has not handed in, where each class is struggling and what each teacher has done this week on the same screen. The Attention list shows what is stuck: papers waiting for a decision, students whose parents could not be e-mailed, e-mails that could not be sent. The School’s Week screen is worked out again from the school’s records every time it opens; leadership sees the number the teacher sees on their own class page.
On leadership’s own screens
- The School’s Week, four numbers. Papers handed in, mistakes corrected, papers waiting for a teacher’s decision this week, and mistakes whose video was watched. Beside every percentage it says how many papers or mistakes it was worked out from; every number opens its details.
- Each teacher’s week. How many new assignments each teacher set this week, how many answers they decided, how many videos they added and how many reminders they sent. Teachers are not ranked; they are listed alphabetically.
- The Attention list. It starts with what is most urgent: papers waiting for a teacher’s decision and how many days the oldest has waited, papers still being marked, students whose parents could not be e-mailed, classes without a teacher or a grade level, and e-mails that could not be sent or have waited for more than an hour.
Today the school leadership’s own account has three screens: School (the School’s Week), Team and classes, and Settings. LGS tracking, Progress and Analysis are teacher screens today, not part of leadership’s own account. The principal is also given a teacher account, with the classes linked to it, and sees LGS tracking, Progress and Analysis there.
Erkan Ulu Okulları
All 15 middle-school classes (grades 5 to 8) use it.
At 4 minutes a paper, reading by hand the 3,031 handwritten homework papers that the AI marked at Erkan Ulu Okulları between 1 September and 7 October 2026 would have taken about 202 hours.
99 real papers were checked again: the AI’s score was right on 96.2% of 1,719 questions and sub-questions. The right score was set not by teachers but by an AI review that looked at the photos again.
In early October, 17 AI solution videos approved by the teacher were opened to the 8th-grade classes.
The system at Erkan Ulu Okulları
- At the school, homework is done on paper, and these papers could not be marked question by question for each student. Savaş Tutumlu started the homework system in March 2026; students began using it in May 2026. The game system was added in September and October 2026.
- The school wanted a grade level’s quiz marked from one scan; the request was in use within a short time.
- On 21 September, 36% of the students with a solution video to watch had not watched a single one. Students were skipping the solution videos and the similar questions, so these steps were tied to a game. Since 8 October, the weekly class coin race has been open to all students.
- A coin is a point that stays inside the school; it cannot be bought.
- Gelgit Adası ran as a closed trial with a selected group of students: the number of students who watched the solution video and tried the similar question roughly tripled within a month. The island is not yet open to all students.
This version, prepared for schools
- This version, prepared for schools, grew out of the system there.
- It is not yet installed at any school; today it runs with an example school, for demonstrations.
- The optical reader and the timetable are not in this package.
A school day
Homework stays on paper.
Morning, at school.
The teacher sets the homework and uploads a photo of the answer key; the AI reads the key; the teacher checks and approves it.
Evening, at home.
The student does the homework on paper, photographs each page with a phone or a tablet and sends it.
A few minutes later.
The AI reads the handwriting. It marks each question and sub-question against the teacher’s key, gives partial credit and explains the mistake. Under every score it says “AI suggestion”; answers it is unsure of wait for the teacher’s decision.
Mistakes, in the Gallery.
Every wrong, partly right or blank question goes into the student’s mistake notebook, the Gallery: a cut from their own paper, “Solve a similar one”, and the teacher’s solution and solution video where there is one.
Correction.
The student watches the question’s video to the end, if it has one, and solves the new similar question by hand on the screen. If they get stuck, hints come step by step. The AI checks the solution.
Next morning, the teacher.
On the Hub, their home page, they see the papers left to them at the top. Analysis shows the question the class missed most. Submission tracking shows who has not handed in what; in one step, every student gets a reminder listing their own missing work.
End of the week, the parents.
The teacher presses “Send to all parents”. Each parent gets their own child’s progress report by e-mail, as a PDF: the score the teacher sees, the questions to look at again, the videos watched and, if the child takes part in Gelgit Adası, this week’s study time.
If the school wants, these steps are also tied to a game: a student who corrects a mistake wins back the coins they missed, and in Gelgit Adası also collects fuel for their boat.

Limits, and what we have not measured
- This version is not yet installed at any school; today it runs with an example school, for demonstrations. It was developed for Erkan Ulu Okulları.
- The time figures are estimates. The time teachers spend with the product, how many answers on real papers will be left to the teacher, and the whole school sending on the same evening have not been measured yet; we measure the teachers’ time and the answers left to them together in the pilot.
- The AI can be wrong. Answers it is unsure of are left to the teacher; the teacher can change any score.
- There is a solution video for the questions the teacher had one made for or uploaded one for; not every mistake has a video.
- The product keeps no official grades or attendance.
- Parents get e-mails; there is no SMS, WhatsApp or parent app.
- In science, the drawings of similar questions come from ready-made templates.
- Otocropper runs on Mac today.
- There is no approval or certificate from the Ministry of National Education.

How we start
Who we are
Stratagem Systems is the software company that Savaş Tutumlu founded and runs. Since May 2025 Savaş Tutumlu has been building software for Erkan Ulu Okulları, a private school in Istanbul; this product grew out of that work. Savaş Tutumlu speaks with your school personally.
1 · Let’s meet.
At your school or on a video call, we show the whole flow in 20 minutes with an example school’s data. In the demo we ask one of your teachers to solve a few questions on a sample paper by hand, without writing a name on it; the AI marks that paper in front of you.
2 · Setup.
We import the teacher, class and student lists. How students sign in and how e-mails are sent is settled with you at setup.
3 · Pilot: one grade level, six weeks.
There is a short call every week. Together we also measure how much time a week your teachers spend on decisions and answer keys. You decide whether to continue.
4 · The whole middle school.
The middle school’s other grade levels are switched on. What would work for primary and high school, we discuss separately.
5 · Training and support.
Teachers get a one-hour introductory training. Setup, teacher training and support come from us.
Frequently asked questions
Does it add work for teachers?
The new preparation for each assignment is the answer key: the teacher uploads a photo of it, checks it and approves it. The AI reads the papers; the teacher looks at the answers the AI is unsure of, the ones they are asked about and the ones they want to look at. There is new work too: watching AI videos before publishing them, and approving names the quiz scan is unsure of and mock-exam keys. Reminders and parent reports go out in one step. How many minutes a week this takes has not been measured yet; we measure it together in the pilot.
Will our teachers’ time really go down?
If your teachers read papers question by question today, it will: the AI does that reading, and the answers it is unsure of are left to the teacher. If they cannot today, the difference is mostly in the work that gets done: every paper is read question by question, and every mistake gets a similar question. How much time teachers spend with the product has not been measured yet; we measure it together in the pilot.
What happens if the AI is wrong?
It can be. That is why the answers it is unsure of are left to the teacher, and every AI score shows as “AI suggestion”; the teacher changes any score they want, and the teacher’s decision goes into the score, to the student and to the parent. A student can also ask about a decision they are unsure of with “Ask your teacher”. Similar questions arrive without waiting for the teacher’s approval; in maths and Turkish our own program draws and checks every similar question, and the teacher edits any they do not like.
Students already solve questions with AI apps; how is this different?
Here homework is done on paper; the student does not see the right answer and the explanation until they have handed in their paper. The AI scores against the teacher’s answer key, the teacher can change any score, and the school and the parents see the result. On a similar question, help comes step by step; the answer is never given at once.
Let’s talk about your school
At your school or on a video call, we show the whole flow in 20 minutes with an example school’s data. In the demo we ask one of your teachers to solve a few questions on a sample paper by hand, without writing a name on it; the AI marks that paper in front of you. You start small: one grade level, six weeks. Savaş Tutumlu speaks with your school personally.
