PensaGrex

PensaGrex is a Googie-themed desktop app that holds what you are doing as a live set of project plans, gathered one domain at a time (HomeLab, Work, and so on). A plan opens at a project node and closes at a terminus, and everything in it happens between the two: you insert a task where it belongs on the line, wrap a run of tasks to name it as a sub-project, and open a branch where part of the work runs alongside the rest. A branch always rejoins the line it left, and a cursor you set by hand marks where you are on each branch.

A domain is drawn as a subway map: stations are nodes, tracks are the lines between them, and a junction is where a branch leaves or returns. Outline colour follows status, so the shape of the work is visible before a single label is read. Every node carries a markdown note.

A domain is plain files on your own disk, one JSON file beside its per-node markdown notes: no account, no cloud, no lock-in. While the app runs it is also an MCP server, so Claude Code can read a plan, add tasks and mark them done as you watch the map change.
