Free Download Yunnan Liandi SiYuan for Windows PC. It is a local-first personal knowledge management system that allows complete offline use while offering secure synchronization with end-to-end encryption.

Overview of SiYuan

This software is designed to help users organize thoughts, ideas, and information in a structured yet flexible way. A block-based approach makes note-taking and knowledge management easier and more effective. The tool supports outlines, bidirectional links, and encrypted sync, making it ideal for building a long-lasting digital knowledge garden.

Key Features

• Local-first storage for complete offline control
• End-to-end encrypted synchronization across devices
• WYSIWYG editor with smooth editing experience
• Block-based design for flexible note-taking
• Support for block reference and backlinks
• Ability to fuse outlines and links to form structured content

• Cross-platform availability for a consistent workflow

How It Works

The tool operates on a block-based system. Instead of relying only on long pages, every piece of content is a block that can be reused, linked, and managed. This makes it easy to connect ideas and avoid losing track of necessary knowledge. Users can create outlines, reference blocks, and visualize connections in their personal knowledge network.

Benefits of Using the Tool

One of the main advantages of this system is that it works entirely offline. Even without internet access, you can continue building your knowledge library. When you do connect online, end-to-end encrypted sync ensures privacy and security. It provides freedom, flexibility, and control over how your personal data is stored and shared.

WYSIWYG Experience

The software features a “What You See Is What You Get” editing mode, making writing and formatting straightforward. Whether adding headings, lists, or links, everything appears in real-time without requiring complicated markdown syntax. This lowers the learning curve and keeps note-taking simple.

Block Reference and Linking

With block references, users can link specific pieces of text from one note to another. This helps eliminate duplication while maintaining context. Bidirectional linking also creates natural connections between ideas, making your knowledge base feel like a living network rather than a static collection of notes.

Security and Privacy

End-to-end encrypted synchronization ensures that your data remains private. Unlike many cloud-based tools, this one is local-first, meaning you own your data first and foremost. Encryption adds a second layer of protection, making it a secure choice for professionals, students, and anyone concerned with privacy.
