English Error Tutor

Problem

Junior high English errors are often repeated signals of grammar gaps, vocabulary misuse, reading comprehension issues, or careless habits. Manually building a wrong-answer notebook is slow, and a single photo of a test page rarely separates questions, handwritten answers, and class notes cleanly.

How It Works

• Multimodal input: accepts photos, album images, typed text, and voice notes, with support for printed and handwritten English.
• One-image, two-path processing: separates error items from class notes in the same picture and creates separate structured records.
• Error diagnosis: locates the error, classifies it as grammar, vocabulary, comprehension, or carelessness, and maps it to Shanghai Oxford English knowledge points.
• Targeted drills: generates similar questions, variant questions, and progressive mixed practice around the same concept, with instant feedback and mastery tracking.
• Notes and papers: organizes key expressions, example sentences, and memory tips, then selects questions by concept, difficulty, and error frequency to produce a PDF test paper.
• IMA note integration: stores errors, drills, notes, reports, and papers under labels for long-term retrieval.

Boundaries

• Optimized for Shanghai junior high grades 6-9 and Oxford English (Shanghai Edition).
• Requires both text and vision models; recognition quality depends on image clarity.
• Needs camera, album, microphone, network, and local storage permissions; IMA Notes is optional.
