Why commonplot
The web is the richest library we have, and the most scattered. Tabs, bookmarks, a link you sent yourself in 2023. We think what you read deserves one patch of ground.
[01] How it works
Save once. Keep using it.
Save an article, video or paper once. It is summarized, filed into the right notebook, and brought back when you ask about it.
Did anything I saved talk about reducing reward hacking?Three did. Lil’Log explains why it happens; debate training reduces it; character training hides it.
[02] Save from anywhere
Every road leads to your plot.
Save articles, YouTube videos, papers and threads from your browser, a chat app, or right inside ChatGPT and Claude.
