Noteside
What Noteside is
Noteside is a free offline notes app that writes plain Markdown files into folders on your computer. It needs no account and, according to its maker, has no sync or cloud round-trip. Notes can be grouped in real subdirectories shown as collapsible sidebar sections. Its block editor supports headings, tables, task lists, callouts, syntax-highlighted code, and KaTeX mathematics. You can use mouse or keyboard controls, vim modes and motions, a searchable command palette, and remappable shortcuts. The maker describes fuzzy search across 50,000 notes as taking about a millisecond. Because files remain ordinary Markdown rather than database records, they can be opened in another editor and backed up. Noteside runs on macOS, Windows, Linux, and the web, with offline access listed. The project uses a Rust core and the operating system webview. The Free plan is free forever, open source, and priced at $0.
