A polished space for notes, tasks, and documents that follows you across every device.
Embed tasks directly inside documents and pair them with a calendar view so planning and execution stay connected.
Choose the structure that matches your thinking — separate work and personal spaces, nested folders, tags, or database-style collections.
Draft, refine, rewrite and summarize content without leaving the document.
Apps for iPhone, iPad, Mac, Vision Pro, Windows and Android with local access when you're offline.

The open-source diagramming studio for builders
Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
Move from system context to containers to components in linked views that all stay grounded in a single architecture model.
