Research does not live in a folder of PDFs you never reopen. In Mena a PDF sits on the canvas as something you actually read — page by page — and every passage you highlight becomes a card on the board, right where you are thinking.
Drop in a PDF and it becomes a live reader with page controls, not a flat thumbnail. Flip through it on the canvas, and when a line matters, highlight it — Mena drops that quote onto the board as its own element, linked to where it came from.
From source to note to card
That single gesture closes the loop from reading to remembering. The highlighted quote is a note you can connect to your own thinking, cluster into a topic, or promote to a flashcard — without ever copying text between apps.
A highlight you never revisit is a sentence you underlined and forgot. Mena brings it onto the page you actually work on.
