Deltos — a cross-platform writing environment built with Avalonia

[tbebekis]

I’d like to share Deltos, a free and open-source cross-platform environment for writing and organizing books and other long-form projects.

Deltos is the modern successor to StoryWriter, a writing application I originally developed years ago for managing novels and their fictional worlds. It has now been rebuilt from the ground up with Avalonia.

Although Deltos originated as a tool for writing novels, it is not limited to fiction. Its hierarchical document structure also supports non-fiction books, essays, technical books, and other structured long-form works.

Some of its main features include:

• Hierarchical organization of projects, documents, folders, and text sections.
• Dual-language editing for bilingual works and translations.
• Reusable components for characters, locations, concepts, organizations, and other project elements.
• Global search, Quick View, and document metrics.
• Export to TXT, Markdown, HTML, and ODT.
• Generation of a static wiki from project content.
• Plain Markdown and JSON files instead of a proprietary database format.
• A sample project for quickly exploring the application.

Deltos currently provides ready-to-use releases for Windows and Linux.

There is no macOS release yet because I do not have access to Mac hardware to build and test it properly. If someone from the community can help produce and verify a macOS build, please let me know.

The project is released under the MIT license.

Nice! Great functionality!

But the UI looks a bit "not so modern" and a dark theme would be welcome, imo...

Thank you! That’s fair feedback. For the first release, I focused mainly on functionality and the writing workflow, so the UI is still fairly traditional. Some visual refinement—and especially a dark theme—is definitely on the list for future versions.

And thanks for explaining the name! 🙂
