TezType Typing Academy

Context

Uzbek learners have never had a serious touch-typing product in their own language. Existing tools treat Uzbek as an afterthought: no Cyrillic track, broken apostrophe handling for oʻ and gʻ, and English-only curricula. TezType was built to be the academy Uzbekistan doesn't have — browser-first, accuracy-first, and honest about results.

Problem

Typing products usually fail in two ways. They either reduce practice to a speed test with no curriculum, or they trust the client to report its own scores — which makes every leaderboard meaningless. On top of that, supporting Uzbek properly is genuinely hard: two scripts, apostrophe rules that interact with keyboard layouts, and digraphs like sh, ch, and ng that need dedicated drills.

Approach

I designed TezType as an academy, not a test. A 60-second diagnostic places each learner and recommends the next lesson. The curriculum builds from home row to full fluency per script, and games exist to make repetition fun after lessons — not to replace them. Scoring was designed server-side from day one: the client streams keystroke events, and the server replays them through a canonical engine before any result counts.

What Shipped

• 302+ lessons across five scripts — Uzbek Latin, Uzbek Cyrillic, English, Russian, and Korean — each with its own keyboard layout and drills.
• A lesson player with a live HUD (net WPM, accuracy, combo, error buffer), an on-screen keyboard with finger-zone coloring, and hand guidance showing exactly which finger to use.
• A 60-second placement diagnostic that measures speed and accuracy, then recommends the right starting lesson.
• Three practice games — a timed speed test, a word-rain arcade mode, and a ghost race against your own record — plus custom-text practice.
• Accounts, streaks, 22+ achievements, public profiles, and leaderboards, with a guest mode that works entirely in the browser.

Results

• TezType is live at teztype.uz with the full academy, games, and leaderboards.
• Every submitted attempt is replayed server-side through the same scoring engine the client uses, and an anti-cheat pipeline flags impossible input patterns — so ranked results are verifiable.
• The Uzbek experience holds up to native scrutiny: correct apostrophe behavior, both scripts as equals, and a fully localized interface.

Technical Notes

The codebase is a pnpm monorepo: a Next.js 16 + React 19 web app, plus shared packages for the scoring engine, keyboard layouts, curriculum content, and database access. The scoring and anti-cheat logic live in one canonical package used by both client and server, which is what makes server-side replay possible without drift. Supabase provides Postgres with row-level security and auth; marketing numbers on the landing page are derived from the real lesson catalog at build time so they can never go stale; and the interface is built on a custom token-based design system with light and dark themes.
