Lexicon - Kotlin Multiplatform Vocabulary Coach

Lexicon keeps language learners in sync on Android and iOS with one Kotlin Multiplatform codebase, guided practice stages, and AI-assisted imports that surface the words that matter most.

Start in seconds on Google Play or grab the iOS build via the App Store.

Why Lexicon Exists

Learners often juggle multiple flashcard apps and lose context between devices. Imports from PDFs, screenshots, or raw text are slow and brittle, and progress frequently drifts out of sync. Lexicon removes that friction with shared UI, persistent state, and automation that extracts vocabulary from any source.

Product Highlights

• Compose Multiplatform renders a single UI layer for Android and iOS.
• Guided stages and focused review help learners move from discovery to mastery.
• AI-powered imports pull vocabulary from pasted text, uploaded files, or screenshots.
• Firebase analytics and KMPAuth provide a unified view of engagement and authentication across platforms.

Architecture & Modules

• composeApp - application entry point, dependency graph, platform hooks
• presentation - Compose screens, navigation, and design system bindings
• domain - pure Kotlin use cases and models
• data - repositories, Room cache, Ktor clients, and sync pipelines
• platforms & core - notifications, secure storage, shared helpers
• design-system, resources, utils, test - reusable UI atoms, assets, helpers, and test kit

Focus on Learning

Whether learners paste text, upload files, or snap screenshots, Lexicon extracts just the vocabulary that matters. Immutable state flows from repositories back to the UI, keeping sessions predictable, testable, and real-time smooth.
