Hanzilyzer helps you understand real Chinese, not just textbook Chinese. Paste or type any Chinese text and get: • STROKE ORDER, ANIMATED: watch every character drawn stroke by stroke, with correct stroke order from trusted open data. • CHARACTER DEEP-DIVES: pinyin, definitions, radicals, components, and etymology hints. Tap any component to explore it. Swipe through every character in a phrase. • INSTANT TRANSLATION: a quick on-device translation of the whole phrase, no internet required. • SPEECH: hear any character or phrase spoken aloud. • AI INTERPRETATION (optional): real messages don't always mean what a dictionary says. Connect your own OpenAI API key and Hanzilyzer explains what a message actually means: multiple plausible readings, the tone behind each one (teasing? sincere? sarcastic?), an example scene showing it in context, and a note on the slang or cultural nuance. Perfect for texts from friends, social media posts, and memes that make no sense literally. Hanzilyzer is built for people learning from real life: chats, songs, and social media, where tone and context matter as much as vocabulary. PRIVACY: no accounts, no ads, no tracking, no data collection. Everything runs on your device. The optional AI feature uses your own API key, stored securely in the iOS Keychain, and sends text only to OpenAI when you ask for an interpretation. Dictionary and stroke data from the open-source Make Me a Hanzi and Hanzi Writer projects (see About & Licenses in the app).

Verdict
The clearest difference is rating: Hanzilyzer at 5.0 against Piazza's 2.1. Piazza's advantage is ratings volume (279 vs 1) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
