Question 1

How does the Zertifly platform work exactly?

Accepted Answer

Zertifly analyzes your language skills using advanced AI technology. It instantly evaluates your writing and speaking exercises, identifies your mistakes, provides feedback, and offers personalized suggestions. It includes exercises in the real TestDaF format and has dedicated study sections for each skill (LV, HV, SA, MA).

Question 2

Can Zertifly be as effective as a real teacher or course?

Accepted Answer

Zertifly is not an alternative to traditional learning methods—it's designed as a complementary force that makes them much more efficient.

The biggest advantage of our platform is providing 24/7 accessible, instant, and fully objective feedback that would be practically impossible for a teacher to offer every student. Our AI analysis measures your performance with the same consistent criteria every time, letting you see your weak points with clear data.

Question 3

On which devices can I use the platform?

Accepted Answer

Zertifly is developed as a responsive web application. You can use it on any device with a modern internet browser, including computers, tablets, and smartphones. Using a headset with a microphone will also provide a better experience, especially for speaking exercises.

Question 4

Why is the platform paid?

Accepted Answer

Zertifly uses advanced AI technologies and continuously updated content. Operating costs of these technologies and ongoing development make pricing necessary. We aim to offer quality education at the most affordable price, considering the budget of students in Turkey.

Question 5

Who is Zertifly for?

Accepted Answer

Our platform is designed for all students preparing for the TestDaF exam. It is especially optimized for Turkish-German University students and Turkish students planning to study in Germany. It offers comprehensive support for first-time test takers, those who want to try again, and students at all levels who want to improve their language proficiency.

Question 6

Why should I use Zertifly when I have ChatGPT or Gemini?

Accepted Answer

General-purpose AIs (ChatGPT, Gemini, etc.) are great for German practice, but they don't have the scoring logic and nuances of a specialized exam like TestDaF. Zertifly's greatest strength lies exactly here: specialization.

Our AI systems are specially trained with real TestDaF data and official scoring criteria (TDN 3, 4, 5). So instead of just offering a grammar correction, you get consistent, exam-goal-oriented feedback from a TestDaF evaluator's perspective. Our platform supports these expert feedbacks with detailed performance tracking, exam-specific vocabulary pool, and personal Redemittel bank, bringing your entire preparation under one roof.

In short, while ChatGPT is a general tool, Zertifly is an expert, complete preparation platform designed specifically for TestDaF success.
