Lyreline Documentation

Lyreline is a native macOS application for documenting repeatable work as it happens. It combines user-initiated screenshots, written instructions, and non-destructive presentation edits in resumable local projects.

Original image masters remain unchanged while crops, redactions, highlights, labels, selected regions, and numbered callouts shape the published presentation. Draft work can be saved, resumed, reviewed, archived, restored, and exported as PDF, PNG, or portable Markdown.
