About Duowenwen: What We Believe and Where the Name Comes From

Duowenwen is an AI homework helper. Our slogan is "Ask away. I'll explain." and our exploration feature is called "Keep Asking". This page covers what we believe and how we work, then how those three names came about, and what we promise and don't promise.

What do we believe?

As long as you're curious, age doesn't matter: you can learn university and even graduate-level material. In the age of AI, the right pace of learning is one where someone is always there to catch every question.

How do we make kids want to learn?

For many kids, the word "studying" sounds dull. Making someone want to know what comes next is what we work hardest on. Ask along the paths you find interesting, and even picking up a single sentence is enough: it's the sentence that makes you want to ask more next time you think of it.

Why explain with pictures?

What we do beyond others is explain with drawings. Many ideas don't need a long passage to read first; one look at a picture and you get it. The needle that keeps turning on our home page is one example: the Kakeya needle, a century-old maths problem you can follow in a six-step animation.

How do we work?

• AI-generated: explanations, question maps and animations are written by AI first.
• Human-checked: a person reads every public page before it's published. In the early days of homework explanations, people spot-check them (looking only at the problem and the explanation, not at who asked), and when we find a wrong explanation we fix the rules.
• Sources shown: answers are checked against the textbook with page numbers. For frontier maths we cite the paper, and where a claim hasn't been peer reviewed we say so plainly.

Who makes Duowenwen, and why?

A very small team makes it. Our first user was a middle-school student in our own family. She'd get stuck on homework in the evening, and nobody at home could explain it, so we wanted to build something that could make a problem clear and let her keep asking afterwards. We counted it as done only when she used it for a real week; if she didn't use it, we changed it.

Where does the name "Duowenwen" come from?

"Duowenwen" is what Chinese parents say, roughly "ask more". Your child says, "This AI is amazing," and you say, "Great, ask it more!" It's something a parent says to a child, meaning: if you don't understand, ask, don't keep it to yourself. We took it as our name because it's already three syllables people say at home.

What does "I'll explain" mean?

"I'll explain" is what the product says next. A parent says, "I just can't explain this any more," and the product says, "I'll explain this one." It stands in the helper's position: it doesn't ask parents to become more patient first, or children to prove they're clever enough first. That's why the slogan is "Ask away. I'll explain.": the first half is what a parent says, the second half is our answer.

What is "Keep Asking"?

"Keep Asking" is the feature name for what happens after an explanation. Every explanation ends with 2-3 follow-up questions, your child taps one, the reply ends with another question, and so on; the questions they ask join up into a question map that can be saved and shared. It's the part we care about most, but it didn't belong on the front door as the name.

Was the name settled in one go?

No, it changed several times. The earliest name was "Keep Asking", because what we most wanted was for a child to keep asking after a problem was explained. But when we said it aloud ourselves, we realised a tired parent's first reaction would be, "Tonight I just want the homework done, not to keep asking." So we tried "Ask Until You Get It", which names the result both parents and children want, but it sounded like an ordinary Q&A tool. Then came "Then Ask Me", which is what the product says to the child: you asked your parents, they couldn't answer, so ask me. That was very close, but what really catches that moment is "I'll explain": the parent says, "I just can't explain this any more," and the product says, "I'll explain this one." The name we settled on, "Duowenwen", is the parents' own catchphrase; "I'll explain" stayed in the slogan and "Keep Asking" stayed in the feature. Not one of the names was wasted.

What do we promise, and what don't we?

We promise one thing: we explain the problem for the parent; we don't hand in the child's homework. After an explanation your child can keep asking; we don't rush, grade or compare. We don't promise your child will definitely learn it, we don't promise any change in grades, we don't write your child's homework, and we don't hand it in. Explanations can be wrong; the textbook and the teacher are the authority.
