canTone is the ultimate high-performance Cantonese lyric-writing tool and vocabulary workspace, built specifically for songwriters, lyricists, and creators. Engineered with a true local-first architecture, it delivers a lightning-fast, fluid search experience—putting a massive linguistic database right in your pocket without ever needing an internet connection. Whether you are matching a strict musical melody, searching for complex poetic rhymes, or building a personalized dictionary of modern slang, canTone gives you absolute control over the Cantonese language. CORE FEATURES: Deep Melody Search: Uncover the exact word you need by searching via precise syllables, loose 0243 melodies, 6-tone/9-tone systems, or traditional Ping Zak (平仄) matrices. Advanced Phonetics & Rhymes: Find perfect rhymes, alliterations (雙聲), and rhyming compounds (疊韻). We even feature a dedicated Tung Rhyme (通韻) mode engineered specifically for traditional literary forms like Cantonese Opera and Naamyam. Custom Vocabulary Engine: Inject your own regional expressions, modern slang, or personal study words directly into the app. The engine seamlessly integrates your entries alongside the core database. Professional Workspace: Browse using browser-like tabs, compare modes side-by-side with Split View, and pin your most-used vocabulary.

LINGUISTIC POWER TOOLS: Semantic Network: Break through writer's block by exploring connected synonyms and antonyms. Advanced Search Operators: Chain modifiers together to filter by tones and rhymes simultaneously. Hunt down polyphones (多音字), reversible words (迴文詞), and monotones (同調詞) with powerful syntax operators.

Visual Melodies: Read pitch contours effortlessly using our custom piano-badge visualizations. ACCESSIBILITY & UTILITY: Built-In Cantonese Keyboard: Type intuitively with our built-in fuzzy romanization IME. Not a strict Jyutping expert?
