Frequently asked questions

It's an AI credential, so why can't I use AI in the exam?

At work, you should use AI. What the exam checks is your judgment: noticing when the AI is wrong and choosing the right tool and settings. Hand that judgment to an AI and there is nothing left to measure.

Do I have to earn the belts in order, like in taekwondo?

The order is only a recommendation. You can start practice and mock exams at any belt right away. Add one specialty on top of Black Belt (1st Dan) for 2nd Dan, or both for 3rd Dan.

Is this an official credential from OpenAI, Anthropic, Google or Kukkiwon?

No. AIDAN is an independent training service, not affiliated with any of them. We write every question ourselves from each company's official documentation and attach the source document to each one.

Can I practice on my phone?

Practice works on both the web and the app. Mock, promotion and Dan exams are taken only in the AIDAN app after a device check.

What if I'm wrongly flagged for cheating?

We never take a belt back on an automatic verdict alone. A person reviews the recorded evidence, and there is an appeal process.
