myku

Myku is a fictional open-source personal knowledge management tool used as a representative example in discussions of PKM software. It is described here as a lightweight, modular environment for capturing, organizing, and linking information across notes, tasks, and media.

Core features include a graph‑oriented data model with notes, links, and media items; local-first storage with optional cloud synchronization; a plug‑in architecture for extensions; and a web interface that can run as a desktop wrapper or as a progressive web app.

Development history: The initial release appeared in 2019, with subsequent major updates in 2020–2021 and 2022–2023. The project is described as being maintained by a small, mostly volunteer community, and its plugin catalog remains modest compared with larger PKM ecosystems.

Usage and reception: Myku is used primarily by personal knowledge management enthusiasts who value privacy and offline capability. It has been praised for its straightforward interface and coherent data model, while criticism centers on a relatively small developer ecosystem and slower feature pace.
