Caspian is your local AI workbench.

Describe a workspace, get a workspace. Caspian builds a workspace per project: your data wired in, your notes on your disk, yours to keep.

Anything can become a workspace

Point Caspian at a diagram, a map, a live feed, or your own API. It builds the workspace around it and your notes pin to the parts that matter, same pattern for a floor plan or a running dashboard.

Local by construction

The whole workspace is files on your disk: notes as plain Markdown, everything else as ordinary code and data you can open, edit, or move. No account, no hosted database, nothing that breaks when a server goes down.

Private vault for your notes

Your notes are plain Markdown files in a vault on your own disk, pinned to the parts of a workspace that matter. Private by default — nothing synced, nothing uploaded, nothing shared unless you decide to.
