A fragmented text editor


2019.01.29 :: 12:27:22 :: lectronice


Opuscule is a minimalist writing and note-taking application with a few twists. Its main goal is to help you write the smaller parts of bigger documents quickly, in any order, with as little clutter as possible, but you can also use it as a simple note-taking or blogging tool. Your notes can then be exported as HTML documents: browse them locally, share them online, or even link them together to build a static website. Opuscule is developed with Godot and is available for Windows, macOS and Linux. Download Opuscule It's free, and will probably go open source if I find enough time to release code I'm not ashamed of.


I am a professional game designer and hobbyist game developer. Writing game concepts and game design documents often means working on several small documents at the same time, depending on priorities and inspiration, and sharing different bits of information with different persons. Opuscule is the result of these considerations, and will evolve for years to come. It's primarily focused on suiting my own needs, so it probably won't please everyone. But I hope you'll find it useful.

Known issues

2018.12.19 :: 10:17:17 :: lectronice


- Moving books (Esc > M > Up / Down) when using a cloud sync client such a MEGA on the data folder can cause some books to be overwritten by the moving book. Shut down your cloud sync client before moving books. - Crashes may happen if you've edited your opuscule files with Notepad. Don't use Notepad, it will mess your files formatting. - Pasting something into the book title text field right after adding the book causes the app to crash.

To investigate

- Crash when adding a page (from position 2) after moving one to position 1.


- LineEdit selection isn't themed, meaning a selected text field on the properties screen can be unreadable with some themes. - Creation and edition dates sometimes seem to be incorrect - Various parts of the FileDialog need proper styling - The focus color of buttons isn't themed yet - When adding a new page, the page title doesn't update in the status bar (possibly fixed) - HTML syntax highlighting seems to slow down the app on lengthy pages. This is a Godot issue.
