Your own questions become the prompts. Recall first, reveal, and mark what to see again.
Lay out screenshots, notes and highlights on a canvas with sticky notes, images and arrows. Export to Markdown or PDF.
A small toolbar appears under your selection. Pick a colour, add a note if you like, done. Highlights come back every time you open the page.

Every collection has a canvas. Screenshots, clips, notes and saved chats appear as cards. Move them, resize them, connect them with arrows, and drop in sticky notes, headings and images. Great for thumbnail ideas, research and study maps.

The side panel keeps your collections, groups and highlights next to whatever you are reading. Search across all of it.

Review mode shows one card at a time. Your question on the front, your highlight on the back. Keyboard friendly: Space, 1, 2.
