Features
Everything an AI tutor should do,
and one thing none of them do.
Most tools answer. Santi Tutor teaches: on a board, step by step, with the reasoning left visible so you can follow it.
Step-by-step explanations
Clear, structured, easy to follow.
Visual diagrams
AI draws on the board to make concepts click.

Pythagoras Theorem
In a right-angled triangle,
the square of the hypotenuse
is equal to the sum of the
squares of the other two sides.
a² + b² = c²

A real lesson board. Toolbar on the left, live transcript on the right, every stroke replayable.
The board
An AI that draws while it explains
Most AI tools hand you a wall of text. Santi Tutor works the way a good teacher does. It writes on a board, sketches the diagram, labels the sides, boxes the answer, and talks you through each stroke as it happens.
- Handwritten working, drawn stroke by stroke in real time
- Geometry, graphs, circuits, free-body diagrams and timelines
- Colour-coded steps so you can see what changed and why
- Scrub back through any moment of the board like a video
Circle theorem
The angle at the centre is twice the angle at the circumference.
Explanations
Every answer shows its reasoning
Ask for the answer and you get the road to it. Each step names the rule it applies, so you learn the method instead of memorising a result.
- Numbered steps with the rule or theorem behind each one
- Ask why a step works whenever you need more detail
- Ask a follow-up mid-lesson without losing the board
- Adjustable depth, from a quick recap to first principles
Step 1
Identify the right angle
Pythagoras applies only here
Step 2
Label the hypotenuse c
Opposite the right angle
Step 3
Substitute a = 3, b = 4
c² = 9 + 16
Step 4
Take the positive root
Lengths cannot be negative
Voice
A teacher’s voice, not a robot’s
It teaches out loud the way a person does: emphasising the part that matters, slowing down on the hard step, and encouraging you when you’re close. Raise your hand and ask, and it stops mid-sentence to listen.
- Expressive delivery with real emphasis and pacing
- Interrupt any time and have the tutor re-teach the step differently
- It asks you questions back and waits for the answer
- Live transcript saved alongside the board
“...so we resolve the weight into two components—”
“Wait, why two?”
“Good, let me redraw the incline with the axes tilted.”
Pause, ask, and continue whenever you need to.
Library
Nothing you learn disappears
Every session is saved as a replayable board plus clean notes. Come back the night before an exam and watch the exact explanation that finally made it click.

Replaying a saved lesson costs no tokens.
Practice
Practice built from your own lesson
The moment a lesson ends, Santi Tutor can generate questions from that exact topic, then mark your working, not just your final answer.
- Questions that build from recall to exam standard
- Feedback on your method and the line that needs another look
- Past-paper style practice for the topics you are studying
- A review queue for the ideas you keep missing
Question 3 of 8
A ladder 5m long leans against a wall, with its foot 3m from the base. How high up the wall does it reach?
- 3.5 m
- 4 m
- 4.5 m
- 5.8 m
Your method was right. You squared 5 and 3 correctly, then added instead of subtracting.
Progress
See what stuck and what did not
A single view of the topics you have mastered, the ones fading, and the ones you have avoided. Keep your next study session focused.
- Topic-level mastery, not vanity streaks
- A weak-topic queue that rebuilds itself as you improve
- Study-time and lesson history in one place
- Clear next steps after every lesson

Coverage
Any subject. Any course. Any level.
Bring a school subject, a university course, a programming language or a professional certification. Santi plans the lesson and teaches it the same way.
Technology & Computing
From a first for loop to system design. Code gets traced line by line as the tutor explains it.
Python · JavaScript · Web Development · Data Structures · Data Science
Business & Economics
Curves, ledgers and models drawn out, so the mechanism is visible rather than memorised.
Economics · Accounting · Business Studies · Entrepreneurship · Marketing
Humanities & Languages
Essays planned, arguments mapped, grammar broken down, with timelines and structure on the board.
English · Literature · Government · History · Geography
Creative & Design
Principles taught visually, because explaining composition without showing it never works.
Graphic Design · UI/UX Design · Digital Marketing · Music Theory
Professional & Exam Prep
Syllabus-aligned lessons and past-paper style practice, marked on method rather than final answer.
WAEC & NECO · JAMB / UTME · IGCSE · SAT & ACT · IELTS & TOEFL
