A connected workspace for school, research & work
Everything you save, finally connected.
The paper is in Downloads. The notes are in another app. The answer you liked is buried in an old chat. Chunk brings the pieces together—so you can see what connects and keep moving.
Your lecture calls it the spacing effect: memory fades along a curve, and each well-timed review resets it. Cramming fights that curve once—spaced practice works with it.12
Connected Chat
Ask one question. See the whole trail.
Ask in plain words. Chunk answers from everything you've saved—notes, PDFs, captures, research—plus the web when it helps. Every answer shows which sources it used and what else connects, so you can follow the trail instead of taking AI's word for it.
What changed between my lecture notes and the newer research?
SEARCHING YOUR CHUNK + THE WEB
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.
How it works
Save it once. Use it forever.
Save
Drop in notes, PDFs, links, lectures—anything worth keeping.
Ask

Keep
Notes, flashcards, and reports stay connected—and automations keep them fresh.
More than one way to use Chunk
Start with the problem you have today.
Cramming for a final, chasing a research question, or juggling a project—pick the tab that looks like your week.
For students
Turn a semester into something you can work with.
Drop in lectures, videos, and PDFs. Build notes, flashcards, quizzes, and concept maps—then ask cited questions across the whole course.

Why Chunk
Your knowledge should compound—not disappear into another chat.
Most AI starts over. Chunk keeps the useful parts around: the note you wrote, the report you ran, the source behind the answer, and the connections between them. Every note you add makes the next answer better.
