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.
The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
Industry standard collaborative whiteboarding with massive template libraries, but less streamlined for rapid AI diagram generation.
