Connected Chat
Ask one question. See the whole trail.
An answer is more useful when you can follow its reasoning. Bring your saved sources into the conversation, check the material provided, and pin a related idea for your next question.
What changed between my lecture notes and the newer research?
ILLUSTRATED EXAMPLE · TRY PINNING A SOURCE
Your notes from Lecture 6 treat the forgetting curve as bad news: memory just fades. The newer research is more hopeful—reviews at the right moments slow the fade, and sleep does some of the work for free.12
The useful connection: the curve isn't a verdict, it's a schedule. The research review you saved lays out three spacing plans that fit a normal week.
One real project
From a good source to your next draft.
What helps people remember what they learn? In this demo project, we gathered research on retrieval and spacing, asked with those sources, and saved the answer as a brief. Here is the working note.
Gather your sources
Give a question its own collection. Add a paper, a link, or a note worth building on.
Follow the evidence
Ask with your selected sources, read the answer, and follow its citations back to the original.
Make it your own
Save the answer as a note. Edit it into a brief, a decision, or something to study.
The Learning research brief, ready to edit in Notes with its sources close by.
