TL;DR

MuseTag is a lightweight semantic annotation language that allows writers to organize their creative work directly within their text. It offers a simple syntax to track characters, locations, plot elements and their relationships, without interrupting the writing flow. Compatible with standard text editors and Markdown, MuseTag naturally integrates into the creative process while providing a structured view of the work. The annotations remain optional and human-readable, enabling authors to focus on their content while maintaining clear organization when needed.

If you are a writer, you might want to read the Quick Start Guide first.

MuseTag is in early development. While dedicated tools are coming soon, you can already use MuseTag in any text or Markdown editor. Want to help shape the project or ask questions? Join our community on GitHub Discussions!

Why MuseTag?

The story below, in MuseTag!

## Why @@MuseTag? @@(me).Pov

As a @@(me).HOBBY[writer], I found myself drowning in character sheets, timeline,
documents, and location descriptions scattered across multiple files and tools.

Every time I needed to check a detail about a character, a specific place, or
an event, I had to break my writing flow to search through my notes.
When and where did @@Jules and @@Isabelle meet for the first time?

I needed a way to keep track of all these elements right within my manuscript,
something that wouldn't force me to leave my text editor or interrupt my
creative process.

That's how @@(MuseTag).CONCEPT[the idea of a simple, inline annotation system]
was born - not as another writing tool, but as a natural extension of the
writing process itself.

As a @@(me).JOB[coder], I would now be able to write tools that could understand
my narrative elements, analyze my story structure, and help me visualize my
characters' relationships.
I could even generate character sheets, timelines, and world documentation
automatically from my text.

The possibilities are endless.
