Keep track of what you & your AI are doing

Build branching plans of tasks in cooperation with your AI. You and your AI can add and edit markdown notes for any task. Drag & drop tasks and whole plans to wherever you want. Flag the tasks you want your AI to focus on. Let your AI change tasks as it works on them, and you’ll see it all happen, as it happens, in PensaGrex.

Create multiple domains of project plans. Add markdown notes to any task. Watch live as your AI edits and updates plans.

The structure is the model.

Projects, tasks, branches. A plan opens and closes, and work that runs alongside comes back: the shape is the work, not a decoration on a flat list.

Legible at a glance.

Status is colour, a fork is a junction, and the leaning marquee shows where you are before you read a word.

For you and your AI.

It is an MCP server while it runs, so Claude Code can read a plan, add tasks and mark them done while you watch the map change.

Connect Claude Code

PensaGrex is an MCP server. Point Claude Code at it and it can read and edit your tasks while you watch the map change.

  1. 1

    Run PensaGrex.

    The server starts on 127.0.0.1:35899 while the app is open; the green MCP dot in the toolbar shows it running.

  2. 2

    Register it with Claude Code.

    Run this once in a terminal (--scope user makes it available in every Claude Code session):

    claude mcp add --transport http --scope user pensagrex http://127.0.0.1:35899/mcp
  3. 3

    Restart Claude Code.

    It loads its connections at startup, so a fresh session sees PensaGrex's tools; confirm with claude mcp list. Keep PensaGrex open while you use them.
