The public, data-free front end of Postfrontal Cortex — a personal second brain: a private markdown wiki maintained by Claude Cowork sessions, browsed through a faithful Windows 98 interface (98.css).
This shell contains no personal data. It authenticates with a fine-grained GitHub
token (stored only in your browser) and reads the private wiki repo client-side.
Try it with sample data: add ?demo=1.
Fork it, point CFG at your own repo, and you have your own Cortex.
