Questions from the bench

What is Chunk?

Chunk is a menu-bar time-blocking app for macOS that helps you plan your day by organizing tasks and calendar events into focused time blocks. It syncs with Apple, Google, and Outlook calendars, includes Apple Reminders integration, offers recurring templates, and provides a live countdown timer and fullscreen alerts to help you stay on track without breaking focus.

Does Chunk sync with my calendar?

Yes, Chunk offers full two-way sync with Google Calendar, Outlook, and Apple Calendar.

Can I use Chunk with Claude or other AI assistants?

Yes, Chunk includes an optional local MCP (Model Context Protocol) integration that lets Claude read your schedule and create, move, or delete events, tasks, and templates on your behalf. The MCP server runs entirely on your Mac, so your schedule never leaves your device.
