Your AI tutor on a live whiteboard
The tutor that draws while it explains.
Ask about anything. PenPal sketches the idea on a whiteboard — pictures, diagrams, math and graphs — talks you through every part, and checks you've got it. In English and Arabic.
6 free credits · no card needed
Learn anything, drawn for you
question → picture → “I get it!”
This is the moment PenPal is for — when the idea finally clicks.
How a lesson works
- 1
Ask anything
Type or say your question — a topic, a homework problem, or “explain it simpler”.
- 2
Watch it come to life
The tutor draws as it talks: a labelled illustration, a diagram that builds step by step, the math line by line.
- 3
It points at what matters
It circles each part while explaining it, then checks you understood with a quick question.
Everything a great tutor does at the board
Hand-drawn illustrations
Labelled sketches of real things — a black hole, a cell, an engine — drawn right onto the board.
Diagrams that draw themselves
Processes, cycles and structures appear stroke by stroke, in the order they're explained.
Math, step by step
Every step of a solution with a note in the margin, plus exact graphs of any function.
A real voice
Natural narration in sync with the drawing. Pause, ask or interrupt at any time.
English & Arabic
A full Arabic experience: right-to-left interface, Arabic handwriting and an Arabic-speaking tutor.
Checks your understanding
Quick questions with instant feedback — and it revisits what you got wrong.
Real lessons, drawn live
Nothing staged: these boards were drawn by PenPal while it taught.

Questions
What is a credit?
One credit is one reply from your tutor — however much it draws: pictures, diagrams, math and voice. Your balance is always shown at the top.
What do I get for free?
6 credits when you sign in with Google. No card needed.
Do credits expire?
No. Credits you buy stay in your account until you use them.
How do I pay?
Securely through Nomod — cards, Apple Pay and Google Pay. Your credits are added as soon as the payment is confirmed.
What can I learn?
Anything you'd ask a tutor: science, math, history, programming, homework problems. PenPal shines when an idea can be drawn.
Does it work in Arabic?
Yes. Switch to العربية and everything changes: the interface, the handwriting, the voice and the tutor's teaching language.
Is my data private?
Your lessons aren't shown to anyone. We keep only your Google name, email and credit balance.
