Org is an Emacs mode for keeping notes, maintaining TODO lists, project planning, outlining, and authoring with a fast and effective plain-text system. Org Mode is simple enough to start using right away, but provides tons of advanced features to support a wide variety of tasks and workflows.
Org-Mode is distributed with Emacs (since Emacs 22.2). This project is under active development and new releases are often available.
- Simple plain text markup for hierarchical documents.
- Built-in table editor: easily format tables and work with spreadsheets in plain text.
