MiaoYan is a local Markdown editor and personal knowledge management tool. It functions as a system for writing and organizing documents stored as local files, supporting the creation of a connected information network through bidirectional links and backlinks.
The project includes a specialized tool for converting Markdown documents into slide-based presentations by using specific content separators. It also provides a command-line interface for managing files, allowing users to create, search, and open documents without a graphical file explorer.
The editor features a side-by-side live preview with synchronized scrolling and supports the rendering of technical diagrams and mathematical formulas. Additional capabilities include local document versioning to track note history and a search-and-replace utility that operates across both the editor and the preview panes.
