## Chunk

Chunk is a time blocking and planning app built specifically for macOS. It lives in your menu bar and slides in with a keystroke (⌘+/) even over fullscreen apps, so you can plan your day without losing your place. The core workflow is simple: open Chunk, drag tasks from your list onto the timeline to create time blocks, and apply recurring templates when a routine needs to fill the day.

What sets it apart is two-way synchronization with the calendars you already use. Apple Calendar, Google Calendar and Outlook Calendar all stay in sync, and Apple Reminders can feed tasks into your day. Tasks, projects, smart lists and recurring templates live in one column, while the schedule can be viewed as a day timeline, a week grid or a month view, with optional PDF or CSV export.

Chunk also includes a local MCP (Model Context Protocol) server for AI planning. Connecting it to Claude Desktop takes one click from Settings, after which you can manage events, tasks, projects and templates in natural language. Because the MCP server is a local process reading and writing directly to Chunk's on-device database, your data does not leave your Mac beyond what Claude itself processes. Chunk is a one-time purchase with a free trial, aimed at people who want deliberate daily planning rather than another subscription.

**Pricing & Plans:** One-time purchase of $39.99 with no subscription. A 7-day free trial is available and does not require a credit card. Requires macOS 12 Monterey or later.

- **Drag-and-drop time blocks:** Drag tasks from your list onto the timeline or apply recurring templates to fill your day with focused blocks.
- **Two-way calendar sync:** Events sync both ways with Apple, Google and Outlook calendars so your plan and your real calendar stay aligned.
- **Multiple schedule views:** Work the same plan as a day timeline, a week grid or a month view, and export to PDF or CSV when you need a copy.
- **Projects and smart lists:** Treat lists as projects with an overview, deadline and finish line, and split large tasks into scheduled sessions.
- **Local MCP server for Claude:** Connect Claude Desktop in one click and plan your day in natural language, with all reads and writes happening on your Mac.

**Strengths:** One-time purchase with no recurring subscription; Two-way sync with Apple, Google and Outlook calendars; Local MCP server lets Claude plan your day without sending data off-device; Available instantly from the menu bar on any screen, including fullscreen apps

**Limitations:** macOS only - no Windows, iOS or Android version; A one-time purchase means you rely on the developer for ongoing updates; Not a full team project management tool; focused on personal planning

## Eraser

Eraser is a technical design platform aimed at the people who document architecture: enterprise architects, DevOps and platform engineers, consultants, and software teams. The core promise is speed without sloppiness, so instead of dragging boxes for hours you describe the system or point Eraser at a source of truth such as code, a cloud account, a CMDB, or a spreadsheet, and it produces a diagram that already follows sensible layout rules.

Beyond static images, Eraser supports interactive maps that zoom from a company-wide view down into a single service, guided explainers that walk teammates through a system, and AI documents for design docs and technical documentation. Team governance features such as shared style presets, naming rules, and reference architectures keep output consistent as more people create diagrams. An open-source agent toolkit and MCP server let tools like Claude, Cursor, and ChatGPT create, search, and export diagrams programmatically.

Prices are organized in tiers that include a free entry point, paid plans, and enterprise agreements, with multi-tenant, single-tenant, and self-hosted deployment options for larger organizations. Security posture includes SOC 2 Type 2 certification and SAML SSO.

**Pricing & Plans:** Freemium with paid plans and custom enterprise pricing. A free tier and free tools such as DiagramGPT are available, while paid individual and team plans plus enterprise agreements cover advanced governance, security, and deployment options; check the pricing page for current rates.

- **AI diagram generation:** Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
- **Maps from live systems:** Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
- **Diagram-as-code integrations:** Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
- **Open-source agent toolkit and MCP server:** Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.
- **Team style governance:** Apply presets, naming and notation rules, and reference architectures so every teammate's diagram ships on-brand and consistent.

**Strengths:** Turns prompts, code, and files into properly laid-out diagrams instead of raw box-and-arrow output; Interactive maps and explainers make complex systems understandable to non-architects; MCP server and open-source toolkit fit agent-driven and self-hosted workflows; Enterprise controls such as SSO, SAML, and SOC 2 Type 2 certification

**Limitations:** Heaviest value comes with team and governance features that need setup; Advanced mapping and self-hosted deployment are aimed at larger organizations rather than solo users
