知织（Tsumugi）是一款面向真实学习场景的 AI 康奈尔笔记学习工具。用户可将网页、PDF、图片等多来源资料归入同一学习主题，逐段精读原文、划词标注并随时向 AI Tutor 追问，再由 AI 基于 RAG 语义检索，将该主题下的全部来源与标注重构为结构化的康奈尔笔记，并可按需生成配图。客户端基于 Flutter（Android），后端基于 Python FastAPI + SQLite，采用 JWT 鉴权，AI 上游兼容蓝心 blue_lm、OpenAI 与 Anthropic，可在运行时切换。
Tsumugi (知织) is an AI-powered Cornell note-taking tool for real-world learning scenarios: users collect multi-source materials (web pages, PDFs, images) into a learning topic, read the original text closely with word-level annotations and on-demand AI Tutor explanations, and let AI restructure all sources and annotations of the topic into structured Cornell notes grounded in RAG semantic retrieval, with optional AI-generated illustrations. The client is built with Flutter (Android); the back end is built with Python FastAPI + SQLite with JWT authentication, and the AI provider (blue_lm, OpenAI, or Anthropic) can be switched at runtime.
