AI Wai Jiao: an AI app for one-on-one spoken English practice

AI Wai Jiao is an AI application focused on spoken English practice, released by Hangzhou Feizhu Technology. It runs on iOS 12.0 or later. The app brings one-on-one English tutoring with an AI tutor to the phone: instead of booking a human tutor or feeling nervous about speaking face to face, learners can start a conversation whenever they want. Its features are organized around the idea of getting users to actually speak, covering casual conversation, pronunciation and grammar correction, exam preparation, vocabulary building, and scenario-based courses.

Key capabilities

• Photo chat: Users can photograph real scenes from daily life, and the AI tutor guides an English conversation based on what is in the photo. Compared with reading sentences from a textbook, this is closer to describing the world in front of you.
• 24/7 human-like language partner: Multiple global tutor roles are available, offering round-the-clock companionship. Learners can start a speaking session at any time without working around someone else's schedule.
• Real-time AI correction: The app corrects pronunciation and grammar during a conversation, provides syllable-level scoring, and gives professional grammar guidance, helping users overcome the fear of speaking or making mistakes.
• Exam preparation: The question bank covers common English exams such as IELTS, postgraduate entrance exams, CET-4/6, KET, and PET. An AI examiner offers 1-on-1 mock exam scenarios and structured model answers based on high-scoring examples.
• AI vocabulary learning: Words are learned in context, with a large set of word books and video example sentences. A vocabulary tutor named Lucy leads the study and answers vocabulary questions, supporting listening, speaking, reading, and writing.
• Harvard scenario lessons: Built on the CEFR framework, these lessons advance speaking skills step by step from input to output, using original film and TV material to reinforce real-world usage through association.
• Pocket translator: Supports photo translation and simultaneous interpretation between Chinese and English, so users can understand and use English in daily life and while traveling.
• AI writing assistant: Provides guidance for high-scoring essays, with one-tap correction, error fixing, and polishing to help users improve their English writing.
