About:
zk is a command-line interface (CLI) tool designed for managing plain text notes with a focus on linking and discoverability. It acts as a companion to your editor, providing commands to create, index, and filter notes while automatically generating backlinks. Its core value proposition is enhancing the Zettelkasten method by making linked notes easily navigable and searchable from the terminal.

Key Features:

Note linking and backlink generation
Interactive note creation and filtering
Built-in LSP (Language Server Protocol) support for editors
Template support for consistent note structure
Content indexing for fast searching

Use Cases:

Building a personal knowledge base using the Zettelkasten method
Managing developer documentation and code snippets
Organizing project notes and tasks in a terminal-centric workflow

Alternatives:

Obsidian – zk is a CLI tool, whereas Obsidian is a GUI application; both focus on bi-directional linking.
Mark – Mark is a similar CLI tool, but zk distinguishes itself with built-in LSP support and a focus on editor integration.
