Time blocking for macOS that plans around your calendar
Drag tasks from your list onto the timeline or apply recurring templates to fill your day with focused blocks.
Events sync both ways with Apple, Google and Outlook calendars so your plan and your real calendar stay aligned.
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.
Treat lists as projects with an overview, deadline and finish line, and split large tasks into scheduled sessions.
AI diagrams and technical design docs built from your code and systems
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.
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.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
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.
