Hashtags, not folders.

Codex takes a page out of social media’s method of organizing large amounts of data by replacing folders with a hashtag system.


Add as many categories
as you like





Must choose one




A notebook page or document often has multiple topics on it. With hashtags you can categorize a single item as many ways as you need.

Community-driven software.

Like our physical products, Codex is driven by community feedback. Unlike our physical products, which take time to produce, changes in Codex are frequent as we continue to pay attention.
