Qingdu is an AI Chinese reader that turns your camera into a fast OCR, pronunciation, and translation assistant. Take a photo of any Chinese characters — textbooks, signs, menus, or notes — and Qingdu instantly recognizes the text with high accuracy, reads it aloud in natural native pronunciation, and provides a translation. Built especially for learners who want to read along and improve as they go. KEY FEATURES - Selective Scanning — Move and resize the camera crop area to recognize only the text you need; your editing mode and last area are remembered - Flexible Playback — Drag the progress bar to a new position, jump between punctuation-based sections, or pause after each section - Fine Speed Control — Listen at 0.1x to 2.0x, adjustable in 0.1x steps - Word Highlighting — Follow spoken words with background highlighting in the source and matching converted text - AI-Powered OCR — Advanced AI recognition delivers exceptionally high accuracy - Pinyin Noise Removal — Automatically filters out pinyin and annotations, extracting only clean Chinese characters - Native Pronunciation — Listen to clear, natural text-to-speech for every character - Instant Translation — Understand what you're reading right away - Edit & Refine — Adjust recognized text for perfect accuracy - Simple & Fast — No login, no account, no clutter. Just open and read WHY QINGDU? Many textbooks print pinyin above or beside the characters, which confuses ordinary OCR tools. Qingdu uses AI to intelligently remove this noise and extract only the Chinese characters you need — giving you clean, accurate results every time. WHO IS IT FOR? Qingdu is designed for learners of Chinese who study with physical textbooks and want a faster, more accurate way to look up, hear, and understand characters. Whether you're a beginner building vocabulary or an intermediate learner reading native materials, Qingdu helps you read with confidence. Start reading Chinese today — just snap a photo and tap.
