Collections
Give every project a home.
PDFs, links, notes, reports, conversations — one shelf per project. Ask a question and Chunk answers from everything on it at once.
What fits on a shelf
Five kinds of stuff. One shelf.
Mix and match — a collection holds whatever the project needs.
Notes
Live references — edit a note anywhere and the shelf always has the latest version.

PDF · DOCX · EPUB · 50MB
URLs
Paste a link. We read the whole page so you don’t have to re-open it.
full-text extraction
Research reports
Deep Research lands its finished reports right on the shelf.
markdown + PDF export
Conversations
Save past chats as reference — the AI learns from where you left off.
full thread history
Collection chat
Ask the shelf anything.
Open a collection and start chatting. The AI answers from everything on the shelf at once — the PDF, the article, your own notes — and shows you exactly which source said what.

Your notes treat locality as settled — but the paper’s section 3 argues the loophole wasn’t closed until the 2015 Bell tests.

Context control
You decide what the AI reads.
Not everything on the shelf needs to be in the conversation. Toggle items in or out of context, and watch the token estimate update — so you always know exactly what the AI is working from.
URL extraction
Links become readable, searchable text.
Add any URL and Chunk pulls in the full text of the page — then writes a quick summary so future-you remembers why it’s there. No more flipping back to the browser to re-read an article.

“A plain-English tour of why entangled particles aren’t walkie-talkies.”
Works with Research
Research checks itself in.
Run a Deep Research query and the finished, fully-cited report lands directly in your collection — ready to chat with alongside everything else on the shelf.
