Projects hold the work together without crowding your day.

Your task list is still yours outside the app.

A Taskmark vault is a folder on your Mac. Tasks, projects, and areas are Markdown files you can read, edit, back up, and move with the tools you already use.

No account, Taskmark cloud service, or opaque database. Work offline, and choose your own file sync if you want it.

Beyond the Mac app

Manage tasks from the terminal or with an agent.

Capture, find, edit, and complete tasks from your terminal. The bundled taskmark command also supports JSON output for scripts and dry runs to preview changes.

Agent Skills

Let a compatible agent work with your vault. The Taskmark skill uses the CLI, while the vault skill guides direct Markdown edits when the CLI is unavailable.
