01 What Is DeepDojo.AI

What You Will Complete in This Lesson

In this lesson, you should first understand DeepDojo.AI’s basic position: it is not a plain knowledge base, and it is not an empty chat box. It is a learning system that combines course paths, AI-guided understanding, flashcard practice, and check-and-review.

After reading, you should be able to explain in your own words what DeepDojo.AI is, and clearly state the major differences from a regular course and regular AI chat.

1.1 Start by Capturing It in One Sentence

When people encounter DeepDojo.AI for the first time, they often understand it as one of two familiar tools:

• Like an ordinary online course, where you read tutorials and materials.
• Like ordinary AI chat, where you ask questions and get answers.

Both are partly right, but neither is complete.

A more accurate one-sentence summary is:

DeepDojo.AI is a learning system of “course path + AI-guided understanding + flashcard practice + check-and-review.”

The key is not a particular button. The learning method is what changes. You are no longer just reading content, and you are not just chatting randomly with AI. You learn around the current task in one course, with understanding, answers, practice, and checks.

You can imagine it like this:

Course path: tells you which lesson to learn now
AI-guided understanding: clarifies when you are confused
Flashcard practice: checks key points one by one
Check and review: tracks current state through diagnosis and reports

With this view, it is easier not to treat DeepDojo.AI as either a regular course or a plain chat interface.

1.2 How It Differs from Regular Courses

An ordinary course usually works like this:

Watch or read material
  ↓
Feel like you understand
  ↓
Use it in future (based on your own judgment)

This approach is common and useful. The gap is that understanding is not the same as being able to use.

You may feel you understand every sentence after one lesson. But when you need to explain it to others, answer questions, or make a judgment in context, you may realize you only understood the words, not the ability.

DeepDojo.AI adds several steps:

Read the current tutorial
  ↓
Ask AI to clarify when unclear
  ↓
Answer a few flashcards
  ↓
Optionally restate, answer questions, or go through diagnosis

So it is not only about whether you “finished reading.” It focuses on whether you can state your understanding, answer key questions, expose uncertainty, and know what to do next.

1.3 How It Differs from Regular AI Chat

The advantage of ordinary AI chat is flexibility. You can ask about any topic, and switch subjects anytime.

In learning, too much freedom can create problems: you talk a lot but lose track of where you are, you receive many answers but leave no personal reasoning visible, and you may feel productive while real mastery is still weak.

DeepDojo.AI places AI inside a course path. AI is not a standalone chat box; it is embedded in the current lesson, current task, and your learning history.

Compare the three:

The boundary of DeepDojo.AI is here: it does not replace your learning, it helps you carry out the process.

1.4 A Common Misunderstanding

New learners often ask a hidden question: if there is AI, do you just let AI give you the answer directly?

AI can and should explain concepts and provide examples. The value of DeepDojo.AI is not “AI generating one more answer for you,” but “making your understanding visible, checkable, and correctable.”

For the same lesson, there are two ways:

The following lessons follow this order: read what is highlighted, clarify what is unclear, start practice when possible, and check state when needed.

This lesson is already enough if you can state this clearly: “DeepDojo.AI is what it is” and distinguish it from ordinary courses and ordinary AI chat.
