DeTeXt vs Hanzilyzer

Finding the symbol you want to use in LaTeX can be hard since you can't memorize all the commands and packages for every symbol. DeTeXt tries to solve this problem by giving you two ways to find the command you want: - Draw the symbol you want and DeTeXt's neural image classification engine will identify what it thinks are the 20 most likely LaTeX commands that will generate a symbol closest to the one you drew. DeTeXt supports Apple Pencil drawings on the iPad. - Search the entire symbol set of 1098 symbols from packages like tipa, amsmath, amssymb, textcomp and more, in addition to the default mathematical symbols. - Copy the symbol, or the character itself, or its Unicode codepoint to the system clipboard, to paste anywhere else. DeTeXt's neural engine processes your drawn symbol and finds the best matches in its symbol database, all on your device without requiring you to be online. All the symbols are stored within the app as well.

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).
