Your to-dos are spread across chat, email and sticky notes, and every time you ask an AI for help you explain again who your colleagues are and what your team's abbreviations mean.
For Office workersTeam leadsPeople who juggle many small tasks
Productivity is Anthropic's plugin that gives Claude a to-do list and a memory of your workplace. Claude keeps your tasks in a TASKS.md file, learns your people, projects and shorthand in a CLAUDE.md file and a memory folder, and adds a local dashboard that shows the tasks as a board you can edit. With a project tracker connected, its update command offers new to-dos and flags stale ones; a deeper scan reads chat, email and calendar. It was built for Claude Cowork and also works in Claude Code; it suits office workers juggling many small commitments.
Your tasks and what Claude knows about your work stay in plain files in your own folder, so you can read and correct them yourself.
Start with the first one: it is a small task you can check easily.
