GeekMemo is designed for people who need "write it down, keep it under control, open it anytime": not another cloud-based knowledge base, but a lightweight, reliable local Markdown notebook.
Your notebook library is just a folder on your disk; each note is a plain .md file, directly readable and writable via Git, other editors, or scripts. Fast cold start, small installer size, ideal for keeping in the Dock. No account required, no cloud sync, and notes are never uploaded by default.
Light & Fast
Native desktop shell—aiming for minimal wait when opening the app, switching notes, or viewing live previews. No bloated runtime bundled; write whenever you think, save immediately after writing.
Fully Local
Remembered path upon launch—continue from where you left off next time. Migration, backup, and version management all happen at the filesystem level; your content always stays in your hands.
Simple to Write, Beautiful to Read
Familiar Markdown syntax with formatting toolbar; left-side editing, right-side real-time preview. Code, formulas, flowcharts, and local images render cleanly. Preview can also be exported as a long PNG image.
Privacy & Security
Default settings do not collect identifiable personal information, do not upload note content, nor perform usage analytics. Optional AI features only connect to the internet when you manually configure an API endpoint yourself—requests go directly to your chosen service provider, never through Z Studio.
