Leanote

Leanote is an open-source knowledge management and collaborative note-taking platform that enables users to capture ideas, write blogs, and share content with others. The platform was developed using Go and MongoDB, and supports Markdown editing with real-time preview, code syntax highlighting across dozens of programming languages, and a distraction-free writing mode. Leanote offers both cloud-based and self-hosted deployment options, with an active open-source community contributing to its development on GitHub. The platform features notebook organization, full-text search, version history with one-click recovery, mind mapping tools, and support for mathematical formulas using LaTeX syntax. Users can also publish notes directly as blogs with customizable themes, and the platform provides Vim and Emacs keybinding modes for power users. Leanote accumulated over one hundred thousand seed users and more than four hundred teams, and serves as a privacy-focused alternative to commercial note-taking applications like Evernote.
