Get it fast. Make it stick.
VPal is each student's own study buddy. Lessons are animated so you see it and get it, practice fits your level, and the tutor always asks back one step at a time instead of solving it for you.
The conversation in the illustration
- Why does the line go down when a is negative?
- Let's look together. Change a from 2 to −2 and watch the line turn.
- Oh! Reading left to right, when a is negative the line goes down.
- Exactly! You just worked out the rule yourself.
Try it now
Three ways VPal is beside you.
Learn something new, practise, ask when you're stuck. Tap each part to see what VPal does.
Lessons that move
Things that are hard to picture are drawn as motion: angles, graphs, molecules. You see it first and memorise the formula later.
- Drag and try it right inside the lesson
- A quick check after every part
Tear off the three angles of a triangle and put them together: they fit a straight line exactly. So the three angles add up to 180°.
Drag a from positive to negative: the line that went up now goes down. The lime dot, where it crosses the y-axis, stays put because b does not change.
Two H atoms bond with one O atom to make a water molecule, H₂O. The two bonds do not line up in a straight line; they fold at an angle.
Practice that fits
Getting it wrong is fine. VPal points at where you are stuck and hints at the next step, so you fix it yourself.
- Hints first, solutions later
- Difficulty follows your level
What is one half plus one third?
Pick an answer. A wrong one is fine, we'll look at it together.
Ask the tutor
Snap your working or type a question. The tutor answers within the lesson you are on, and asks back so you work it out yourself.
- Photograph your working to ask
- Asks back instead of handing over the answer
- Photo of working: 2x + 3 = 13; 2x = 13 + 3; x = 8
- Where did I go wrong?
- Line 1 copies the problem correctly. On line 2, when you move 3 to the right side, what happens to its sign?
- It has to become minus! 2x = 10, so x = 5.
- Exactly. You found the mistake yourself; I only asked.
Each student, a different explanation
One question, a different explanation for each student.
VPal is the coordinator: it picks the questions, exercises and way of explaining to fit each student's level. Someone new to a topic sees a picture first. Someone who has it down gets an extra challenge.
An, Bình and Chi are fictional characters.
Why isn't 1/2 + 1/3 equal to 2/5?
Look at these two bars. Half a bar and a third of a bar are not cut the same size, so you cannot add them directly. Cut both into 6 equal parts: 3 parts plus 2 parts is 5 parts.
To add, two fractions need the same denominator. Try rewriting both over 6:
Once they are filled in, add the two numerators and keep the denominator.
You got it: 5/6, because you have to find a common denominator first. Try a slightly harder one.
VPal grows with you
VPal grows up. You go further on your own.
At each school stage VPal changes shape and the way it guides. The older you get, the further VPal steps back so you can walk by yourself.
Seedling
A playmate that leads step by step
- Shape
- Round, short, big eyes, rosy cheeks, very expressive
- Voice
- Cheerful, chatty, praises specifically
- The V
- A two-leaf sprout on its head
Study buddy
Asks back and solves with you
- Shape
- Taller, with arms, a cheeky raised eyebrow
- Voice
- Funny, often asks “Why is that?”
- The V
- The sprout grows into a two-lock hairstyle
Companion
Plans and keeps you on your goal
- Shape
- Slim, neat, calm eyes, no rosy cheeks
- Voice
- Brief, respectful, like an older student
- The V
- Shrinks to a small, slender tuft of leaves
Partner
Appears only when needed
- Shape
- Minimal, floating, no arms or legs
- Voice
- Offers one line and lets the learner decide
- The V
- Becomes a smile, close to the logo
Age is only the default. You choose when VPal grows up, and each step up is its own moment.
For teachers
Plan with AI. One lesson, used in two places.
Describe the lesson you want to teach and VPal drafts it with you. The same lesson can be projected in class and becomes an animated lesson students continue at home.
- Each class has its own course and you pick the lessons
- A bank of exercises comes with each lesson
- After you assign it, VPal explains further at each student's level
