Take notes with your favorite Markdown editor, and explore them with Cosma.

Software comes and goes, but data should last. Cosma brings you a global view of your knowledge graph, without interfering with your storage, editing and versioning practices.

Visualize

From a directory of text files written in Markdown, Cosma generates a collection of records gathered in a single HTML file: the cosmoscope.

Zettlr is an ideal writing partner for Cosma. Need another text editor? Cosma will work regardless, and it also includes a form to help you quickly create a file in the appropriate format, ready to be edited with your favorite application.

Explore

Browse your knowledge using the full heuristic palette of the cosmoscope: search engine, filtering by record types, index, keywords, focus mode, saved views, in-context links and backlinks, automatic citation processing…

Cosma can accommodate all kinds of records and relationships. You can rapidly build a small hierarchical glossary of terms. Or you can patiently accumulate a vast personal documentation containing various types of notes.

Adapt Cosma to your needs: define graphical features according to record or link type; tweak the graph drawing algorithm; customize the appearance of the cosmoscope in CSS.

Share

Share a cosmoscope by email, on your personal website, via a third-party service… It is a standalone HTML file: each person who opens it will have access to the same data and tools as you.

Each cosmoscope also contains a JSON representation of your records, their relationships and the bibliographic references cited. This structured data that can be reused in other software, from Gephi to Zotero.
