Memex puts your Markdown notes and PDFs on an infinite canvas, with an AI chat that reads them. Any document can sit on the canvas as a live, readable card. Arrange and connect your cards, write around them with Apple Pencil, and ask the chat about what you have gathered. ON THE CANVAS - Markdown documents render as live cards, not links - PDFs sit on the canvas as cards showing their first page - Draw arrows between cards and gather them into groups - Handwrite and sketch next to your typed notes with Apple Pencil - On iOS 27, search finds your handwriting as well as your typed notes - Push cards to another canvas as your thinking changes - Type @ to link to anything in your library, or @here to link the spot you are on - Add text, code blocks, tables, images and embeds CHAT WITH YOUR NOTES - Add a card, a whole document or a PDF to the chat, or type straight in - Ask about your notes in plain words - Put any reply back on your canvas as a card - The chat is there on canvases, documents and PDFs MAKE IMAGES - Select typed text, or handwriting on iOS 27, and tap Make image - The picture lands on your canvas and in your library YOUR FILES STAY YOURS - Documents and canvases are plain files in your iCloud Drive, visible in the Files app - No Memex account, no lock-in - The AI sees only what you add to the chat.
