Cloud Outliner vs Leo Editor

Cloud Outliner is an outlining app for organizing plans, projects, and ideas as interactive notes. Its editor supports drag-and-drop reordering, multi-selection, checkboxes, automatic numbering, item notes, rich-text formatting, and highlighting. A multi-tier document manager adds color stickers, password protection, customizable templates, and document duplication. Search covers outline names and text; entries can be collapsed or expanded, filtered by checked status, and viewed in light or dark themes. The maker says outlines sync through iCloud and Evernote. Export options include PDF, OPML, HTML on macOS, and plain text, with sharing through email, instant messaging, and listed social or Apple services. It runs on iOS and macOS, with iOS read-only mode, indentation gestures, orientation support, and wireless keyboard shortcuts. Downloads are free with in-app purchases; Pro plans add cross-device sync and remove banners or ads.

Leo Editor is a free, open-source programmable editor, outliner, and knowledge base for arranging code, writing, and research in flexible outlines. It runs on Windows, macOS, Linux, through an API, and as self-hosted software. Cloned nodes allow one idea to appear in several outline locations while remaining synchronized. Navigation includes expanding and collapsing, hoisting, promoting, clones, and clickable links, with backlinks available for related sections. Users can automate workflows with Python scripts, commands, and plugins. Outlines export to HTML, MORE, Markdown, Org mode, reStructuredText, and Vim outline formats. Jupyter integration lets @jupytext nodes represent notebook cells and save changes back to .ipynb files. The leoBridge module exposes Leo content to Python host programs. A WebSocket server accepts JSON queries and changes, using password challenge-response authentication; TLS is optional. Leo requires Python 3.9 or later and is distributed under the MIT license.
