AI Scrabble Practice

Five AI-powered practice tools backed by a 370K-word dictionary

Video Demo

El Problema

Scrabble practice tools are either too simple (word checkers) or too powerful (board solvers) — neither builds actual skill. Players bounce between fragmented sites for validation, anagram solving, and word discovery with no structured practice mode.

La Solución

Five tools share a single 370K-word dictionary and a consistent interface — Word Validator, Word Finder, Anagram Solver, Magic Search, and the Practice Game — so players stay in one application for an entire session. Magic Search uses GPT-4o-mini to translate plain-English queries into validated, scored word lists, while the Practice Game runs timed rounds with realistic tile draws and on-demand AI hints. Server-side API proxies keep credentials off the client, and a type-safe i18n system delivers full English and Spanish support with locale-based routing.

Características Principales

  • 370,105-word dictionary with sub-millisecond validation via Set-based O(1) lookups
  • Anagram solving in under 500ms for 7-tile hands with wildcard support
  • 5 practice tools unified in a single bilingual interface
  • AI-powered natural language word search and timed practice with hints
  • Full E2E test coverage with Playwright across all features and locales

Resultados

Five distinct practice tools consolidated into one app — no context switching
Sub-millisecond word validation and under-500ms anagram solving
Client-side dictionary architecture handling 370K entries with O(1) performance
Full E2E coverage across features, dark mode, and English/Spanish locales

Overview

The AI Scrabble Practice Suite is a full-featured web application that consolidates five practice tools into a single, fast interface. Players validate words against a 370,000+ entry dictionary, discover high-scoring plays, solve anagrams, search with natural language, and practice under time pressure — all running client-side with sub-second response times.

Version 2.0 introduced two AI-powered features. Magic Search translates plain English queries ("7-letter words ending in -ING with a Z") into validated word results with Scrabble scores. The Practice Game runs timed 5-minute sessions with realistic tile draws and on-demand AI hints, simulating the pressure of competitive play without a board.

The app ships with bilingual support (English/Spanish), dark mode, responsive layouts, and a Playwright E2E test suite covering all major features.

The Challenge

  • No learning curve in existing tools: Word checkers confirm validity but don't help players discover new words or understand scoring patterns. Board solvers play the game for you.
  • Fragmented workflow: Players bounce between separate sites for validation, anagram solving, and word lookup — losing context and momentum.
  • No structured practice: No tool simulates timed play with realistic tile draws, progressive difficulty, and intelligent feedback.
  • Language barriers: Most Scrabble tools are English-only with no internationalization support.

The Solution

Unified tool suite: Five tools share a single 370K-word dictionary and consistent UX — Word Validator, Word Finder, Anagram Solver, Magic Search, and Practice Game. Players stay in one application throughout their practice session.

AI-powered discovery: Magic Search uses GPT-4o-mini to interpret natural language queries and return validated words with scores. Server-side API proxies keep credentials off the client while maintaining fast response times.

Timed practice with coaching: The Practice Game generates realistic tile draws (vowel/consonant balance), runs 60-second rounds, and offers AI-powered hints on demand. Scoring rewards longer words with progressive bonuses, encouraging players to push beyond safe short words.

Bilingual interface: A type-safe i18n system with React Context provides full English and Spanish support with locale-based routing, making the tool accessible to a broader player base.

Technical Highlights

  • O(1) word validation: 370K words loaded into a Set for instant dictionary lookups, even on mobile
  • Custom anagram algorithm: Letter frequency counting with wildcard support processes the full dictionary in under 500ms
  • Server-side API proxies: Vite dev middleware routes /api/definition, /api/magic-search, and /api/practice-hint through server-side endpoints, protecting API keys
  • Type-safe i18n: React Context with typed template variables and locale-based routing (/ and /es/ prefixes)
  • MSW integration: Mock Service Worker enables development and testing without live API dependencies
  • Full E2E coverage: Playwright tests cover all pages, dark mode, responsive layouts, and Spanish locale routing

Results

For the End User:

  • Five distinct practice tools consolidated into one application — no context switching
  • Sub-millisecond word validation and under-500ms anagram solving
  • Natural language search lowers the barrier to word discovery
  • Timed practice builds real competitive skills

Technical Demonstration:

  • Client-side dictionary architecture handling 370K entries with O(1) performance
  • Server-side API proxy pattern keeping secrets off the client
  • Type-safe internationalization with locale-based routing
  • Full E2E test coverage across features, themes, and locales
