# Leftmark

> Leftmark is a Mac app, now in beta: a local kanban board for AI coding agents. Claude Code, Codex and Gemini log every request to it over MCP and keep each ticket current, so you can see what every agent is running, what's done, what's stuck and what's waiting on you, without reading their chats.

- Runs on your Mac (Apple Silicon, macOS 13 or later). The board is one SQLite file. No account, no telemetry, no AI calls of its own.
- Every ticket keeps the agent session that worked on it, with a command to resume that exact Claude Code session after the terminal is closed.
- Questions from agents and runs waiting for approval land in a "Needs you" lane, with Reply on the card.
- It tracks rather than orchestrates: you keep using your agents as before. @mention an agent on a ticket to hand it a task in its own worktree.
- Projects claim folders, so an agent in a work folder can't read a side project's tickets.
- In beta and invite only. Request an invite: https://app.youform.com/forms/966adulq
