ii · the problem

1.5 billion
people
“learn” English.

Most apps teach them to translate apple and collect streaks. Completing a tree does not help you order coffee.

The gap between your last green checkmark and your first real conversation is where everyone falls.

The apps know this. They’ve added chatbots and speaking drills. None of it is survival — which is the only context in which adults actually acquire a language.

iii · the insight

Language is a survival skill, not a school subject.

This is not a new idea. It has been published, peer-reviewed, and replicated for forty years. No consumer product actually applies it.

  • Krashen1977

    Language is acquired, not learned — through comprehensible input.

  • Swain1985

    Output plus corrective feedback is necessary for fluency.

  • Schmidt1990

    Adults need to consciously notice a pattern to internalize it.

  • Long1985

    Tasks drive acquisition — not rule-first instruction.

اصل المعنى原義

Denotation. The literal dictionary meaning of a word.

لازم المعنى含意

Pragmatic meaning. What a word actually does in context — connotation, idiom, register. Wahori tracks both, separately, per learner.

scenario · café · day 3

A sample conversation

Maya · barista

Hey, what can I get started for you?

You

“Can I get a large coffee, no sugar?”

Maya · curveball

room for cream?

helper · arabic

بيسأل إذا بدك تتركي مساحة بالكوب للحليب. جاوبي 'yes, please' أو 'no, just black'.

“No, just black. Thanks.”

vi · why now

Two unlocks in the last eighteen months.

01 · edge llms

NPCs that run on the device.

Gemma 4 edge holds a character across turns at acceptable latency. Two years ago: impossible. Now: every player gets a café full of distinct people whose consistency comes from data, not scripted trees.

02 · phonetic ml

L1-calibrated pronunciation feedback.

wav2vec2 fine-tuned on non-native English, plus Goodness-of-Pronunciation scoring, distinguishes intelligible from confusingat per-phoneme granularity. An LLM can’t do this — it can’t hear.

مخارج الحروف調音位置

Places of articulation — the mouth positions we encode per learner, per source language, per phoneme.

vii · the moat

It’s not the LLM. Anyone can call a model.

The moat is the pedagogy, encoded as data. Reproducing Wahori requires a linguist-engineer pair willing to spend months on mock-scenario calibration. That’s the asset.

  • i

    100+ calibrated mock scenarios

    vocab, grammar, curveballs, register, phonetic demands — authored by a linguist, reviewed by linguists

  • ii

    L1 tolerance matrices

    per-phoneme three-band models for Arabic and Japanese — pedagogical data, not model outputs

  • iii

    Curriculum rules engine

    data-defined rules for when to introduce, surface, and re-expose — tunable without redeploys

  • iv

    Four-layer tracker schema

    vocab × meaning, grammar patterns, phonetic profile, competency per vertical — feeding every prompt

viii · market

Real numbers, not TAM fantasy.

~400k

Working Holiday visas

issued annually across EN-speaking countries — highly motivated learners with a deadline

50M+

Adults relocating

each year, globally, where English is the daily operating system — work, healthcare, housing

~

The app-graveyard cohort

tens of millions who bounced off flashcards — SRS-fatigued adults looking for something that works

MVP focus: Arabic and Japanese. Maximum linguistic distance from English. If the system works for them, it works for Spanish, French, Mandarin, and the rest.

x · roadmap

Where we are. Where we’re going.

  1. Phase 0now

    Architecture locked · spikes in flight

    15-spike program running: edge LLM feasibility, phonetic ML, 100-scenario calibration corpus.

  2. Phase 1next

    Vertical slice

    One scenario end-to-end — every system represented in its minimal form. Proof the architecture holds.

  3. Phase 2

    Content scale-up

    The remaining eight scenarios authored on the slice's rails. Linguist contractors onboard.

  4. Phase 3

    Closed alpha

    Real AR and JP learners. Measuring retention + learning gains with instrumented play.

  5. Phase 4

    Public beta · next raise

    Open the doors. Waitlist converts. Raise for art, audio, and full-game production.

xi · team

Zach

founder · engineer · linguist

Years learning languages. Formal linguistics study. Years shipping software. Owns both pedagogy and engineering until the team grows — which is rare, which is why Wahori works.

Arabic & English. Working in Japanese phonology. Building the thing I wish had existed when I first tried to survive in a language that wasn’t mine.

Joining as we go.

  • 01Contract linguists for the 100-scenario calibration corpus and L1 tolerance matrices
  • 02Native-speaker voice talent (Canadian, NYC, Australian English; AR and JP for helpers)
  • 03Artists + animators for the 3D full-game post-MVP

Nobody acquired a language from a streak.

Adults acquire languages by needing them.

Wahori gives them the need.
