Caspian
Anchor your notes to anything.
Caspian is a local-first knowledge base that lets you anchor plain Markdown notes to anything: a diagram, a map, a floor plan, a 3D model, over a vault you own.

Hey PH 👋 My notes never lived where my thinking did so I built Caspian: anchor notes to anything visual: a picture, map, or 3D model. Drop a pin, write in plain Markdown, navigate by clicking anchors instead of digging through folders. Best part: every note is a plain Markdown file on your disk. No account, no cloud, no lock-in. It's early (v0.1). Windows + Linux live, macOS soon. Would love your honest feedback 🙏
