Knot - Minimalist Cross-Scenario Recording Tool

🌟 Project Overview

Knot is an intelligent multi-scenario recording tool inspired by the minimalist concept of ancient "knot-tying" memorization. By integrating core modules such as todo lists, smart notes, and document reading with multi-platform client support, we create a full-scenario productivity toolchain.

Etymology: Just as ancient civilizations recorded important events with physical knots, we continue this simple yet efficient concept through digital "knots".
