Dendron

Dendron is a note-taking tool that lives inside your code editor. It treats your notes like code, organizing them in a flexible, hierarchical file structure. Instead of a flat list of documents, you create notes within notes, building a tree of knowledge that can grow as complex as your projects do. This means you can have a note for 'projects.client.website.backend.api-spec' just as easily as you'd navigate folders in a codebase. Everything is stored as plain text Markdown files, so your data stays portable and under your control.

What sets Dendron apart is its focus on structure and scale for technical users. It uses schemas—think of them as blueprints or templates—to define consistent note types and relationships, bringing a type system to your general knowledge. Features like daily journals, scratch notes for quick thoughts, and a powerful lookup command let you cache and retrieve information with just a few keystrokes. It's open-source and integrates deeply with VS Code, offering a fast, keyboard-driven workflow that feels native to developers.

This tool is a natural fit for software engineers, researchers, and anyone who deals with complex, interlinked information. It's perfect for managing meeting notes across multiple projects, building a personal wiki or digital garden, planning software features, or consolidating research notes. If you're already living in VS Code and want your knowledge management to be as organized and scalable as your code, Dendron provides the structure to make that happen.
