Chunk, a macOS menu bar time-blocking app with Claude AI integration.

Technical Positioning

A high-performance, native productivity tool for time-blocking that integrates AI for schedule management.

SaaS Insight & Market Implications

Chunk differentiates itself by prioritizing native performance (Tauri/Rust) over the bloated Electron alternatives common in the productivity space. The integration of Claude AI via a local MCP server is a sophisticated approach to data privacy, ensuring that sensitive schedule data remains on-device. By combining traditional time-blocking features with AI-driven automation, the product targets the 'productivity power user' segment. The one-time purchase model is a clear value proposition against the subscription fatigue prevalent in the SaaS market. Success will depend on the reliability of the two-way sync with Google/Outlook, which is historically the most difficult technical hurdle for calendar-based applications.

Show HN: Chunk – macOS menu bar time-blocking app with Claude AI integration

Chunk is a native macOS menu bar app for time-blocking your day. It floats above all windows – including fullscreen apps – so your schedule is always one shortcut (Cmd+/) away without ever leaving your flow.Key things I built into it:- Drag-to-create/move/resize time blocks on a 24-hour timeline, with a live countdown in the tray icon
- Two-way sync with Google Calendar and Outlook (create, move, resize, delete events back to source); Apple Calendar read-only
- Things-style three-column task sidebar: lists | tasks | day view, with Apple Reminders integration so you can drag reminders onto the timeline
- Templates + Routines – build a reusable day structure and auto-apply it on chosen weekdays
- Fullscreen notifications that flash the block name across your entire display at task transitions
- Claude AI integration via a local MCP server – Claude can read/create/edit your schedule, todos, and templates. Everything runs on-device; nothing leaves your Mac except what Claude itself processes
- Built with Tauri 2 (Rust backend + React/TypeScript) so it's fast and lightweight, not ElectronIt's a paid app (one-time purchase) with a free trial. No card required to try it – just download and run.Happy to answer any questions about the implementation
