About

HiWord.AI helps you learn English words you can actually use: a few new words each day, met again in an article, a sentence to read aloud and a conversation. Learning one word well beats memorizing a hundred. HiWord gives you a small set of words each day and carries them from flashcards to practice, reading and speaking, so "I recognize it" becomes "I can say it." TODAY'S PATH Three steps a day: flashcards, practice, and an article written with your words. Shadowing and AI Talk are there whenever you want to speak, and they earn XP too. AI TALK Chat with five AI partners, each with their own personality, voice and level, from a patient beginner coach to a sharp investor. Talk about your day and use today's words. Every session ends with a short review of what went well and what to rephrase. SHADOWING WITH FEEDBACK Read a sentence after the native audio and get instant feedback on accuracy, rhythm, stress, fluency and clarity, down to the word and the sound. READING AND DAILY NEWS Read articles written with the words you're learning, with bilingual support, full-text audio and tap-to-look-up. A short Daily News brief in plain English arrives every morning. PRACTICE Sentence tiles, listening, matching and fill-ins. When you pick a wrong answer, HiWord tells you what that word means. ASK HIWORD Ask in English or Chinese. Look up a word, a phrase or a whole sentence, find natural ways to say what you mean, check whether your own sentence sounds right, and see how two words differ. IMPORT YOUR OWN ENGLISH Bring in links, text, photos, documents and audio, or share straight from Safari and other apps. HiWord turns them into articles you can read, listen to and practice with. GAMES You Describe, AI Guesses: see a secret word and give clues in English until the AI guesses it. No timer, so take your time. LEADERBOARD A weekly board that resets every Monday. Cheer on the people learning with you. WORDBOOKS Daily English, Ogden 850, KET, PET, IELTS, Gaokao, CET-4, CET-6, Business, Crypto, PSLE, World Cup, F1 and more. Every word comes with phonetics, part of speech, Chinese meaning and example sentences. ON IPHONE, IPAD AND APPLE WATCH Optimized for iPhone Duo: learn on the full inner display and keep your place when you fold or unfold. Home Screen and Lock Screen widgets show what to study next, and you can review cards on Apple Watch. Your progress syncs across devices, and core learning works offline. HIWORD PRO HiWord is free to download, and flashcards and practice are free. With HiWord Pro you can use AI chats, shadowing packs and imports without holding back. HiWord Pro is an auto-renewable subscription. Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel it in your App Store account settings.

What's New in HiWord.AI

1.3.29

November 11, 2026

HiWord 1.3.29 makes speaking to Ask smoother and brings Bubbles to AI Talk. Ask - After you speak, choices appear under what you said: for Chinese, how to say it, casual or formal; for English, check the grammar, make it more natural, or explain the meaning - Type Chinese and you get natural ways to say it in English - Recent searches shows everything you've saved and filters as you type; clearing asks first AI Talk - Bubbles is now in the Talk list. Tap to play You Describe, AI Guesses or Scene Flashback - A game with Bubbles counts toward today's Talk step Reading - Long-form X Articles shared to HiWord now import Wordbooks - The spoken phrases deck grows to 300 sentences, with new negotiation, work and everyday scenes, and new learners start with it - Shadowing a sentence from this deck practices just that sentence, without a follow-up example Flashcards and practice - Long words, phrases and definitions no longer push the example off the card; after you tap an answer, the card slides away in that direction - Practice has fewer typing questions and a few shadowing questions again; a shadowing attempt that doesn't pass isn't counted as wrong Home - Today's path shows how many steps there are before you start and how many you've done after; the streak card marks the milestones you've reached Fixes - Accounts with a lot of study history no longer get stuck syncing; changes reach the cloud again - Buttons share the same press feel, and buttons you can't use yet look unavailable - Shadowing stops the model audio before recording starts, so it no longer gets recorded
