- Mac users who read and annotate PDFs
- Worth noticing
- The site says each answer is saved inside the PDF, with a page citation that jumps to and verifies the quoted passage.
Field notes
The described workflow starts with selected text: readers can choose a built-in question such as Define or Simplify, or enter their own, then keep the response with that passage. Glossa says citations link to the source page and verify the quoted words. The page also lists scanned-PDF text recognition, full-text search, and exports to Markdown, TextBundle, Anki, or Obsidian.
