Smultron Overview
Smultron is a text editor for Mac from Peter Borg Apps. It handles plain text, notes, and source code in one tidy window. Syntax highlighting covers more than 200 languages, including Swift, Python, JavaScript, and Markdown. Advanced Find supports regular expressions. Compare shows color-coded differences between two files. Snippets, Commands, and a Functions list speed up routine coding. Bookmarks and Notes help you navigate long documents. Split window and Focus mode help you compare or concentrate. Autosave and Versions protect your edits. The app is optimized for Apple silicon. Version 14.5.1 runs on macOS 14 Sonoma or later. It suits writers, developers, and anyone who wants a light editor that is more capable than TextEdit.
