Tomboy

Tomboy is a free and open-source desktop notetaking app written for Windows, macOS, Linux, and BSD operating systems. Tomboy is part of the GNOME desktop environment. As Ubuntu changed over time and its cloud synchronization software Ubuntu One came and went, Tomboy inspired various forks and clones. Its interface is a word processor with a wiki-like linking system to connect notes together. Words in the note body that match existing note titles become hyperlinks automatically, making it simple to construct a personal wiki. For example, repeated references to favorite artists would be automatically highlighted in notes containing their names. As of version 1.6 (2010), it supports text entries and hyperlinks to the World Wide Web, but not graphic image linking or embedding.
