• CLI and editor integration: command options, diagnostics, local editor behavior, and language-server setup.
• Python API: compile, export, inspect, and package from Python.

The product page provides the current download. The source archive includes editable examples covering notes, editorial layouts, mathematics, chemistry, page masters, and interactive media. A rendered notes example shows actual compiler output. Download its editable source to try it locally.

Hamen Markup is free under the MIT license. No account or cloud service is required to write notes. Python dependencies and the optional Chromium download require a network connection during installation.
