Notes That Help You Learn
Most note apps are just text boxes. You capture information, then it disappears into a folder. You never review it, never test yourself on it, and eventually forget you wrote it.
Synthesis is different. A freeform canvas for visual thinking, 34 block types for any kind of content, and AI-powered spaced repetition that surfaces what you need to review.
