We learn better when we write. Putting an idea in our own words forces us to understand it. Connecting it to other ideas helps it last. MyZettel is a canvas for that work. Each thought gets its own short note. Related notes sit near each other. Links come as you write. Over time, the canvas becomes a map of what you understand. - An infinite canvas: put notes where they make sense, and move them as your thinking changes. - Links from writing: link a note while you write. Every link shows which way it goes, even to a note far away. - Read in place: open a linked note without leaving the one you are reading. - Note types: keep rough thoughts, your own conclusions, and ideas from a source apart. - Search and a minimap to find any note on a large canvas. - Made for iPhone, iPad and Mac. - Free to use. No sign-up. No third-party servers. MyZettel is inspired by the Zettelkasten method, but you do not need to know it to start. A sample canvas in the app shows how it works.
