LexiGo doesn't teach textbook Chinese — it teaches Chinese you can actually use the moment you land. Whether you're travelling to China, on a business trip, a short-term exchange, or a work posting, LexiGo gets you fluent in the Chinese that actually matters — fast. The word bank is organised around nine real-life scenarios: airport communication, getting around the city, checking into hotels, mealtimes, shopping, everyday conversation, socialising, business communication, and emergencies. It includes 515 high-frequency words, layered across two difficulty levels (L1/L2). Finish one module, and you're ready to handle that one specific situation. 【Built for "going to China," not for exams】 The word lists aren't there to help you pass a test — they're organised around real situations: airports, hotels, ordering food, bargaining, asking for help. The first sentence you learn is one you can actually use in real life. 【Rehearse with AI before you say it for real】 Before you set off, practise booking a room, asking for directions, or ordering food with the AI inside the app. The AI carries the conversation forward within the scenario and corrects you the moment you slip up, so you won't freeze when the real moment comes. 【A custom word list built around your trip】 Tell the AI which city you're heading to, how long you're staying, and what you plan to do — it'll generate a word pack made just for that trip. 【Keep learning on the plane, or in a subway with no signal】 The word bank, pronunciation, and dictionary lookups are all stored on your device. On-device search means core learning works fully offline. 【Privacy by design — nothing kept on file】 No username or password required — the app generates an anonymous ID automatically the first time you open it. Chat history stays on your phone only; nothing is saved on our servers. Signing in with Apple or Google is entirely optional, and only used to recover your progress if you switch devices. 【Core features】 · Tiered vocabulary + spaced repetition: learn by module, with each word tracked at a 0–5 proficiency level and a next-review date — due words move automatically into your review queue · Pinyin and tone practice: a dedicated pinyin trainer covering all four tones plus the neutral tone, with native-speaker audio · AI scenario dialogues: pick a scenario and work through a Chinese conversation with the AI — booking a trip, a business visit, studying abroad, daily life, or just free chat · AI-generated custom word packs: after a conversation, the AI summarises your trip into a personalised word list, automatically generated and added to your local vocabulary · Offline semantic dictionary lookup: the on-device dictionary supports meaning-based search, even offline — connect for an AI-generated definition when you want more detail · Streaks and stats: track your learning streak and study/review stats, and share your progress as a card LexiGo itself is completely free — full access to learning, review, pinyin practice, and offline dictionary lookup, limited only by an "energy" cap (20 points, which regenerates over time or can be topped up by watching a rewarded video ad). For unlimited energy, an ad-free experience, online AI search, and AI-generated custom word packs, you can subscribe to LexiGo Pro. 【Terms and Policy】 Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://learnzh.app/privacy
