Leanote

Leanote, also known as Ant Note, is an open-source cloud-based note-taking and blogging platform designed for individuals and teams who want to capture, organize, and share knowledge. The service provides real-time Markdown editing with live preview, syntax highlighting for all major programming languages, and a built-in mathematical formula editor with LaTeX support, making it especially popular among developers, researchers, and students. Users can create notebooks, manage documents, and publish content directly as blogs with multiple customizable themes. Leanote offers desktop and mobile clients so notes stay in sync across devices, and it supports team collaboration through shared notebooks and member management. A WeChat mini-program version lets users record voice and images on the go and turn curated notes into public blogs with one tap. With features such as a distraction-free writing mode, full-screen presentation view, and import or export options, Leanote positions itself as a lightweight yet powerful alternative to commercial note tools, serving a global community that values openness, Markdown workflows, and self-hosted flexibility.
