A team's shared notebook

Pages written only from the cards people chose to publish, where every sentence names who said it. When someone takes their words back, every page built on them is rewritten without them.

A recorded demo. Ana, Ben and Cara are invented. Their pages were written by a language model (a cloud model, for this recording) from their signed entries, with every sentence checked against what it cites, and recorded before and after Cara takes hers back. Nothing here is live, and nothing you do is sent anywhere.

Your shared notebook is written only from cards people chose to publish, and every sentence names who said it.

Code checks every citation; whether a sentence keeps the meaning is checked by a model in a narrow band. A real shared notebook runs on a team's own machine. When someone takes a card back, it stops showing that card at once and rewrites the pages; the stored copy stays on that machine, unserved, and nothing can make a reader forget what they already read.
