AT A GLANCE / THE THESIS

The architecture
of sovereign learning.

Built from first principles for 260M Indian students: hardware-enforced focus, 100% offline edge compute, and radical economic relief for families.

TAM / INDIA K-10

₹91,000 Cr

260M students carrying 6–8kg backpacks daily. Targeting 1% penetration (2.6M units) in 5 years.

LOCAL-FIRST EDGE

100% Offline

On-device neural inference at 9.2 t/s with sub-200ms latency. Zero packets leave the hardware.

FAMILY ECONOMICS

73% Savings

Saves over ₹95,000 per child across 5 years compared to traditional recurring spend.

BATTERY LIFE

4 Days

Zero backlight eye fatigue. Dual 7.5″ bi-stable panels engineered for all-day reading in direct sunlight.

01 / THE DEVICE & INTERACTIVE TESTBED

Not another screen.
A thinking surface.

Most learning apps ask for attention. KiTab gives it back. Two e-paper pages separate the problem from the conversation, so a student can stay with an idea long enough for it to become theirs.

✦ Move cursor to tilt in 3D • Draw on left page with stylus • Adjust STEM variables below

CBSE STEM SYLLABUS :

✦ Rotate phone horizontally for the immersive dual 7.5″ e-paper workspace

PHYSICS / CLASS 09 03:14 PM

FORCES ON AN INCLINE

What makes
the block slide?

Slope Angle: 30° (g = 9.8 m/s²)

10° (gentle)35° (slip)65° (steep)

Draw force vectors or equations here...

SAHĀY / LOCAL NEURAL ENGINE ● ON-DEVICE NPU

Sahāy Socratic Engine Offline • 9.2 t/s • 0ms Cloud Latency

Before we write equations—what would happen to the block if friction was zero?

It would accelerate down faster.

Spot on. Move the slope slider above to 45°. Notice how the parallel gravity component mg·sin(θ) overcomes friction!

02 / THE EXPERIENCE

The tutor
that waits.

KiTab does not race to an answer. It notices the work, diagnoses the misconception behind the attempt, and offers the smallest useful next step.

✳

It sees the
thinking, not just
the answer.

Every sketch, revision, hesitation pause, and erasure gives the tutor a diagnostic signal about where understanding breaks down.

Learner Stroke: Vector N (90° Ground Error) 0.18s latency

"Learner drew normal force perpendicular to ground instead of incline. Surfacing angle decomposition reminder."

↗

It gives
handholds,
not shortcuts.

Hints arrive strictly in earned stages. Ki begins with a diagnostic question, then a spatial cue, and only provides a worked connection after verified student effort.

STAGE 01 Diagnostic Question

"What force component opposes sliding along the incline?"

STAGE 02 Spatial Vector Cue

"Decompose gravity into components along and normal to the plane."

STAGE 03 Physical Analogy

"Compare parallel pull (mg·sinθ) with static friction limit (μ·N)."

STAGE 04 Mastery Challenge

"Calculate acceleration: a = g(sinθ - μ·cosθ) for θ = 45°."

⌁

It works where
the internet
doesn’t.

The learning engine, on-device tutor, and encrypted student record live 100% on the device. No cloud latency. Zero monthly subscriptions. Zero student tracking.

Network Radio 100% Air-Gapped (0 KB/s)

External Cloud APIs None (Zero Outbound)

Hardware Sovereignty Fully Autonomous

03 / CBSE STEM CURRICULUM

A first device for a whole learning life.

Made for the
next hard thing.

KiTab begins with CBSE grades 8–10 STEM: the critical years when a learner’s foundation in maths, science, and computational thinking is formed.
