Is Chunk right for you?

A good fit for

Mac users who plan focused work alongside Apple, Google or Outlook calendars and want an assistant to manipulate that schedule.

Before you choose

Requires macOS 12 or later. The MCP server is local, but schedule context supplied to Claude follows that assistant’s processing policies. Check generated edits and use the external-calendar lock when changes should stay read-only.

Plan and verify a working day

Connect your calendars and bring tasks into Chunk. Enable Settings → AI Integrations for the local MCP connection, then ask Claude to place specific tasks around existing commitments. Inspect the resulting times and calendar destinations before relying on the plan.

Purchase and information handling

The official site offers a seven-day trial and lifetime access through a one-time purchase. A current amount was not confirmed in the evidence reviewed, so no monthly price is shown. Local database storage does not make Claude processing local: context sent in an assistant prompt can still reach its provider.
