Open Source Software Library

Jupyter Book is an open-source tool for building publication-quality books and documents from computational material. Jupyter Book allows users to write their content in Markdown files or Jupyter notebooks, include computational elements (e.g., code cells) in either type, include rich syntax such as citations, cross-references, and numbered equations, and using a simple command, run the embedded code cells, cache the outputs and convert this content into: a web-based interactive book and a publication-quality PDF.

Mluva is a native dictation and rewrite workspace for Omarchy, maintained by Daniel Večeřa in Czechia. Press F9 to record, keep the original beside an editable rewrite, and copy the completed text into your work. The GTK4/Libadwaita app includes searchable history, Markdown and JSON export, and a theme-aware Quickshell widget. Speech recognition and rewriting are independent provider choices: local speech is available, while cloud services need the user’s credentials and may charge. Omarchy is the maintained desktop target. The software source is Apache-2.0.
