Share with Cleanse.
Leave with the useful part.

How A True Polymath Learns
Big Think
True polymaths don't learn many fields in parallel. They pick one until they can teach it back in plain words, then pick a second that bends the first. The cross-field instinct is a byproduct of going deep, not the goal.

The same save, now with room to compare it against the library.

05Keep / copy / share

Read the useful version, then put it where it belongs.

Keep it in your library, or send it onward with the original link still attached. If Cleanse only got the title and a few details, the summary tells you that plainly instead of guessing. You always know what you are passing along.

Your context

What you do with a save should not become a public profile.

Shared summaries

What you send can stand on its own without exposing your whole library.

Light by default

Cleanse should do the useful small thing before it asks for anything heavier.

Honest when it knows less

A link-only save starts as a link-only save until there is more to know.

The iPhone alpha is for people with more curiosity than time. If you live in YouTube, the Mac app is already out and handles your Watch Later today.
