Product preview
Overview
TheBrain is Obsidian if the graph should look like a star: a thought in the center, jumps out. Roam is bullets; this is a plex.
It is older than the PKM wave. The product is the jump. If notes should be a map you fly, this is the graph. If they should be files, Obsidian.

Leaving Obsidian for a map
Visual PKM, not Markdown
Bottom line
The flying graph — TheBrain if PKM should be a star, Obsidian if it should be files.
