Leo: organize code and ideas your way#
A programmable editor, outliner, and knowledge base
See your work from every angle.
Leo keeps code, writing, and research in a flexible outline. Cloned nodes let the same idea appear in multiple places—without duplicating it.
One workspace, many ways to think
Outline anything
Navigate large projects as a meaningful hierarchy instead of a pile of files.
Reuse without copying
Leo's clones place one node in multiple contexts while keeping its content in sync.
Automate your workflow
Use Python scripts, commands, and plugins to shape Leo around the way you work.
