Instead of blindly solving a large number of problems, the AI ​​accurately diagnoses your skill level and fills your study materials with problems exactly what you need right now.

You can continue using it without making a payment.

■ Students Don't Know What They Don't Know

Many apps start with prompts like, "Try selecting your weak chapters."

However, students who can choose those topics are already not at a loss.

Gangnam Chat doesn't ask. Solve just a few problems, and the system sets your starting point.

If you report a grade of 5, the warm-up consists of only two problems.

■ Diagnoses and Heals Your Weaknesses

It analyzes your solution process to pinpoint which concepts or problem types you are getting stuck on.

Then, it selects and presents problems that fill those gaps, precisely addressing the areas you don't know.

If the real reason you can't solve high school problems lies in middle school concepts, it goes down to that level.

If you need a review of middle school math, it rebuilds your knowledge starting from the common foundations. (This diagnostic and healing algorithm is filed as Patent Application No. 10-2026-0135592.)

■ See your location at a glance with a concept map (node ​​map)

On a map that breaks down mathematical concepts into small parts, you can visually check how solid your understanding is and where your weaknesses lie.

Even if you have no prior math knowledge, you can see exactly where to start on a single screen.

■ It does not immediately tell you the correct answer even if you get it wrong

Most apps show the correct answer immediately. Then you just think, "Oh, I see," and move on, leaving your skill level unchanged.

Gangnam Chat only provides hints and gives you a chance to solve the problem again.

If you are curious about the answer, you can open the explanation at any time, and there are no restrictions on viewing the explanations.

■ Unlimited Unit-by-Unit Mock Tests

Unit-by-Unit mock tests are the only way to raise your verification grade, and there is no limit on the number of attempts.

Once you raise your grade, it will not drop. You will not lose your grade even if you take a break.

** ■ My Quest — No Backlog of Homework

Set your own "By Date, Grade Level" and fill in the blanks.

If you fall behind, the deadline is automatically extended. Red numbers do not accumulate.

■ Brain Engine — Blend Concepts Through Reading

This is training to read and solve passages in Math, Science, Humanities, Case Law, and Social Studies.

You are too busy keeping up with lectures to have time to blend concepts in your head.

This is for students who can do calculations but cannot solve word problems.

■ Full Mock Exam and A4 Evaluation Report

We summarize your actual grade estimate, strengths and weaknesses, time management, and next study direction on a single A4 sheet.

The app takes over the conversation you would hear during academy consultations.

■ Ask via Photo (Photo Chat)

You can take a picture of a problem you are stuck on and ask about it.

Gangnam Chat does the rest. It provides follow-up problems based on the same concept.

(Captured images are not stored on the server.)

■ Reliable Problems and Solutions

· 100% human verification of 3,768 questions in the 1st problem database

· The formula engine independently recalculates and verifies the correct answer (AI does not verify problems created by AI)

· Patent application for diagnosis and healing algorithm No. 10-2026-0135592 (July 23, 2026)
