Understand more,
consume less.
PSI turns long-form content into tuit — critically assessed knowledge units, condensed and designed for human understanding.
The object
What is a tuit?
A tuit is a knowledge unit distilled from long-form content: a video, article, talk, report or podcast.
It condenses the essentials, surfaces sources, separates fact from opinion, and helps the reader decide what deserves their attention — before spending time on it.
Etymology The word comes from tuition — in its older sense of the act of teaching, of passing on knowledge. The tuit is the livelier heir of its slightly clunky parent: the synthesis note.
Does dark matter really exist?
The method
Four pillars
Time saved
Consume less useless content. The immediate benefit.
Reliability
Decide with more confidence. Our differentiator.
Intelligence
Understand faster and better. The analytical value.
Neutrality
Form your own judgment, without prescription. Credibility.
The knowledge map
Four knowledge phyla
A phylum is not just a school subject: it marks the content's dominant method of inquiry. Each title reveals its pedagogical subtitle on hover or keyboard focus.
One color, one signal.

The ecosystem
The institute's tools
PSI is built as a suite of instruments serving human understanding. The first is already live.
Video synthesis notes
Automated critical analysis of YouTube videos from selected authors. Bilingual synthesis, reliability scores, referenced sources.
