Shelf feature
Sketch and type beside PDFs
Not every page is a PDF. Shelf supports sketch canvases and rich Doc pages — including a research writing suite with citations and export — in the same collections as your uploads.
What you get
- Sketch pages for diagrams and handwriting — pinch or Ctrl+scroll to zoom
- Doc pages for structured typed notes and research drafts
- Citations, outlines, and export on research Docs
- Live in collections alongside PDFs
- Open in the same tabbed reader workspace
When a concept needs a quick diagram or a paper draft you type yourself, you do not need a separate notes app. Shelf keeps notes and research Docs one click from the PDFs they cite.
