LUMI, YOUR TUTOR, SPEAKS FIRST
Finally, a tutor that draws while it talks.
SketchMind speaks with you like a real teacher — agrees a plan, then teaches one idea at a time on a living notebook. Notes, sketches and math appear in perfect sync with its voice.

Why does a ball move?
Force = a push or a pull
Push: closing a door, sliding a chair
Pull: lifting a school bag, opening a drawer
A force always acts between TWO objects
TAKEAWAY
No force → no change in motion.
Checkpoint ahead — Lumi asks, you answer

✦ Picture this: a football resting on grass — a boot swings in, motion lines, the ball flies off… SKETCHING…
fig 1 — the kickFORMULA
F = m · a
force = mass × acceleration — measured in newtons (N)
| EFFECT | EXAMPLE |
|---|---|
| Starts motion | kicking a ball |
| Stops motion | brakes on a cycle |
| Changes direction | a goalkeeper's deflection |

HOW IT WORKS
Talk. Watch. Ask.
A lesson with SketchMind is a conversation — with a board in the middle.
1
Talk it out
Say what you're studying — Lumi plans the lesson with you.
I have a physics test on Friday.
Let's plan it: Forces → Newton's laws → practice. Sound good?
2
Watch it draw
Ideas ink onto the board exactly as the voice explains.

Ask, anytime
Doubts welcome — checkpoints make sure it stuck.
CHECKPOINT
Is gravity a force?
Yes No
WHY IT STICKS
Built like a great teacher's notebook.

FAQ
Good questions.
Q What can SketchMind teach? +
Maths, physics, chemistry, biology, computer science, coding interviews, history, languages and more. The tutor adapts its depth to the subject — and to you.
Q Do I have to read walls of text? +
No. Lumi talks first. You listen while the board draws the idea — notes, sketches and math appear in sync with the voice, one beat at a time.
Q How much does it cost? +
Free gets you up to 2 full lessons a day — no card needed. A Pro plan with higher daily limits, voice narration, sketched figures and PDF export is coming soon.
Q Can I revisit old lessons? +
Every board is saved. Reopen a lesson to review it, continue where you stopped, or export it as clean PDF notes.
Q Do I need to install anything? +
No. SketchMind runs in your browser — laptop, tablet or phone. Sign in and your notebooks follow you.
Q Is it for beginners or advanced learners? +
Both. Say “simpler” and it re-explains with a new sketch. Say “go deeper” and the lesson expands. Checkpoints keep it honest about what you've actually understood.
Q Why not just use ChatGPT? +
Chat gives you a wall of text to read. SketchMind teaches: it speaks, draws figures and math in sync, pauses to check you understood, and leaves you a notebook you can revisit — closer to a tutor than a chatbot.
Q Is it accurate — and safe for kids? +
Lessons stick to educational content, and checkpoints catch misunderstandings early — if something looks off, ask and Lumi re-derives it step by step. Kids' accounts stay private: notebooks are never shared without you.
