The diagram below shows the full product structure in one view. Read it top to bottom: learner at the top, the Shell wrapping everything in the middle, the three Pilot modules inside it, and the platform it runs on at the bottom.

The Shell — Relationship Layer

Knows the learner. Holds their history. Shows up the same way every time.

Persistent across
every session

💬

Conversational onboarding

Dialogue, not a form. Goals, background, and communication style gathered as a conversation.

🧠

Persistent memory

Every session opens with proof the Coach remembers — what was hard, what was achieved, where to next.

👩‍💻

Matched 3D avatar

Culturally matched Coach appears at key moments — session open, feedback, close. Steps back otherwise.

🔄

Re-engagement

Picks up exactly where the learner left off — a day, a week, a month later. No guilt. No starting over.

Shell wraps each module — Coach appears before & after every session

🔢

Numeracy

Bold & alive

Fast-paced gamified sessions on any phone

Adaptive difficulty — calibrates automatically

Mid-session exit saves exactly — resume where you left off

Coach connects skill to learner's stated goal

Coach absent during gameplay — game is foregrounded. Reappears after for feedback.

📖

Reading

Calm & intimate

Learner reads aloud — Coach tracks word-by-word

Works from any text — a letter, a form, a book

Word stumbles handled calmly — no red marks

All feedback spoken aloud, not just displayed

Coach listens in the corner while learner reads. Speaks after — never interrupts.

✍️

Writing

Warm & encouraging

Paper-and-photo pathway — write on paper, photograph it

No keyboard required — universal access

Spoken feedback — specific, never a score

On-screen pathway also available

Coach appears after photo upload — delivers feedback as a warm spoken conversation.

What this diagram shows

The diagram has five layers, read top to bottom.

The Learner

The three primary personas — Alyssa, Deb, Marcus — plus an "any learner" slot. The breadth of that row is deliberate: My Coach is designed for any phone, any pace, any background. The device and connection constraints are built into the baseline, not treated as edge cases.

The Shell — Relationship Layer

This is the heart of the product. The Shell does not teach — it knows the learner, holds their history, and shows up the same way every time. Four capabilities define it: conversational onboarding (no forms), persistent memory (demonstrated every session), a culturally matched 3D avatar (present at key moments, absent otherwise), and re-engagement (picks up after any gap, no guilt).

The Shell is what makes this different. Every other tool in this space is a content pathway. My Coach is a relationship. The Shell is that relationship — and it persists across every module, every session, every gap.

The three Pilot modules

Numeracy, Reading, and Writing each have their own visual personality and interaction model — but they share the Shell. The connector label between the Shell and the modules says it plainly: the Coach appears before and after every session. Within each module, the avatar's behaviour is deliberate:

Numeracy: the Coach is completely absent during gameplay. The game is foregrounded. The Coach reappears after to deliver feedback.
Reading: the Coach listens quietly in the corner while the learner reads — present but not speaking. It speaks after, never during.
Writing: the Coach appears after the photo is uploaded — delivering feedback as a warm spoken conversation, not a results screen.

Future modules — same Shell, new capabilities

The dashed cards show where the platform goes after the pilot. Because the Shell is a separate layer from the modules, new skill areas plug in without rebuilding the relationship. Oral communication, digital literacy, financial literacy, employability skills — each extends the Coach's reach. The learner does not start over. The Coach already knows them.

The investment case in one sentence: funding the pilot establishes the Shell — and everything else plugs into it.

The platform layer

The bottom band shows what the product runs on at launch: any smartphone browser, on 3G or Wi-Fi, with no app to install. The faded entries (tablet, kiosk, TV) show Phase 2+ reach — present in the vision, not the pitch.
