Cuby Text: Open-Source Block-Based Knowledge Management

Cuby Text is an open-source knowledge management tool designed to organize information into modular blocks. This structure results in a cleaner workspace and makes specific data easier to retrieve. Because your data is stored locally on your machine rather than in the cloud, search performance is exceptionally fast. Cuby Text is compatible with Windows, Linux, and macOS.

1. Clean, block-based pages The application treats every element as an individual block. This modular approach provides a flexible and intuitive way to structure your notes.

2. Rich text + Markdown shortcuts The editor supports a hybrid workflow. You can use standard rich-text formatting or utilize Markdown shortcuts, such as typing ** for bold text, / to trigger the command menu, or [[ to create internal links between documents.

3. Multiple tabs The interface supports multiple tabs, allowing you to keep several documents open simultaneously and switch between them without losing your progress.

4. Auto-generated outline and graph view Cuby Text automatically generates an outline for every page to improve navigation. Additionally, the integrated graph view provides a visual representation of how your notes and ideas connect.

5. Cross-platform The software is available for macOS, Windows, and Linux, ensuring a consistent user experience across different operating systems.

6. Local-first storage All information is stored within a single SQLite database file on your hard drive. This local-first architecture ensures your privacy remains intact while making data backups and transfers straightforward.

The document manager also features a "Recent Documents" list, complete with timestamps for the latest edits, and a dedicated trash bin for managing deleted files.

Cuby Text is built upon a selection of established third-party libraries and frameworks, including a specialized block editor, Preact, Force Graph, SQLite, and Electron. The development philosophy focuses on two main principles: minimizing external dependencies and selecting tools that are easy for the community to learn and contribute to.

To date, there have been four releases. The codebase consists of 91.2% TypeScript, 6.9% SCSS, 1.5% JavaScript, and 0.4% other languages.
