Caspian

What is Caspian?

Caspian lets you attach notes to images, maps, 3D models, webpages, and other visual canvases. You can drop pins or draw regions, then write notes in plain Markdown for each anchor. It keeps everything in a local vault on your own disk, so your notes stay portable and readable in any text editor. The app is built for people who want to navigate ideas spatially instead of digging through folders or a graph view. One setup, no account, and no cloud required.
