Its mobile experience is a progressive web app for iOS and Android that syncs and works offline; the Web Clipper can collect tasks, bookmarks and notes from web pages and services including Gmail, Zendesk, Jira and GitHub. The free plan includes unlimited hierarchical lists and sharing, Markdown, due dates, tags, mobile offline use, browser extensions and Open API. PRO costs $3.90 per person per month, billed at $39 per year, and adds features such as task assignment, repeating tasks, Google Calendar synchronization, 2 GB of file storage and MCP access.

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.
