One notebook per question.
Create a notebook for a paper set, a literature review, or a single question. Its sources, threads, and outputs stay scoped to it.

Scoped by default.
A notebook owns its own sources, threads, and generated outputs. Asking a question in one notebook never pulls context from another, so a side investigation cannot quietly contaminate the review you are writing.
- Sources, threads, and outputs belong to the notebook that created them
- Answers draw on the set you assembled, not everything you have ever uploaded
- Open several notebooks without their contexts mixing

Add a source once.
Uploaded PDFs, papers found through search, and pasted web pages land in your library. Link one into as many notebooks as you need instead of uploading it again per project.
- PDFs, papers, Markdown notes, and web pages in one library
- Link an existing source into a new notebook without re-uploading
- Deleting a source from a notebook leaves it available to the others
