Every item shows its page
Cards, questions and knowledge points all carry a page chip. Not "somewhere in this document" — a page.
One upload, in numbers
A nine-page lecture PDF, run through once. The middle column is the layer this page is about.
One tap opens the source on those lines
The reader opens beside your cards and highlights the passages the point actually rests on — bounded to the text, not a block of color over the column.
If it can't be located, no card is made
This is the part most tools skip. A generator that always produces something will sometimes produce something that isn't in your file.
Plenty of tools cite a document. Fewer cite a page. Fewer still cite the lines. Fewer still refuse to write a card they cannot cite.
