Features, in full

The whole toolkit for a well-run day.

Focus without the friction.

Chunk is a macOS-native time blocker built on one surface: slide from your tasks and projects to your calendar, and plan a day, a week, or a month in the same place.

Calendar view

Everything about a block, one click away.

Plan on a day, week, or month timeline with your tasks and your Google, Outlook, and Apple Calendar events side by side. Click any block and its editor opens right next to it, so you can change the details without leaving the calendar.

Tasks

Every task in one place, a drag from your day.

Tasks is where your work lives before it lands on the calendar. Smart lists sort it for you, your projects and templates hold the rest, and any task opens up for the details. Slide to Plan and the same column opens its projects in place, with the calendar right beside them.

Projects

Big projects, one session at a time.

Lists are now projects, each with an overview for the plan, a deadline to work towards, and a finish line you can tick. Split a big task across several sessions, or drag the whole project onto the calendar and decide what to work on when the time comes.

Analytics

Your schedule, completion, and follow-through in one dashboard.

See how your time actually goes. Compare 7, 30, and 90-day ranges across two sections — Time, for what you planned, and Tasks, for what got done.

  • 7, 30, and 90-day ranges with previous-period deltas.
  • Planned hours, task completions, follow-through, and active days.
  • Time: scheduled hours, where your time goes, time of day, and block lengths.
  • Tasks: completions, deadlines met and missed, and how your routines held up.

Talk to your schedule. Claude handles the rest.

Chunk ships a local MCP (Model Context Protocol) server. Connect it to Claude Desktop in one click and plan your day in natural language — with your data never leaving your Mac.
