CrossLine vs Fractal Note

CrossLine is a free, open-source outliner for Windows, Linux, and macOS. It arranges text as parent, child, and subtopic nodes that can be collapsed or expanded, and supports cross-links and Ted Nelson’s transclusion concept. CrossLine also works as a full-text database with a built-in search engine; Lucene can be added as an optional alternative when building the application. Navigation includes search, history, and back/forward controls, with backlinks supported. HTML and CLDX are listed export formats. Precompiled downloads cover Windows and Linux in x86 and x64 versions, plus Mac x64 and M1. The compressed executable can be unpacked and run without installation or special privileges. The README says the Windows build runs on Windows 7 without a separate Microsoft runtime. On Mac, startup requires the context menu’s open command. The project links to a demo repository, provides source-build instructions using LeanQt, and directs support questions to GitHub issues or email. Licenses listed are GPL-2.0 and GPL-3.0.

Fractal Note is a free, MIT-licensed note environment inside VS Code. It combines a WYSIWYG Markdown editor with outliner, database, mindmap, and file-manager views. Notes remain plain Markdown and JSON files organized through a virtual folder and file tree. Full-text search covers outlines, Markdown pages, and PDF, Word, Excel, and PowerPoint attachments. A built-in viewer handles Office documents, PDFs, HTML, images, and text or code files. The Chrome extension clips web pages into an outliner or Markdown and writes them to disk through the File System Access API. Backlinks, collapse and expand controls, subtree scoping, filtering, and PDF or Markdown export support navigation and sharing. Bidirectional S3 sync and Amazon Translate require AWS credentials; HTTP(S) proxy connections for those services are not supported. Published AI skills support note searching, reading, and writing in named AI IDEs.
