Instant, zero setup
Pure static pages with no sign-up or install; all rendering and computation happens in your browser, even on flaky connections.
Data stays local
Sort arrays, chart data, flowcharts and samples are processed locally, and clipboard history never leaves this browser.
Visual by design
Frame-by-frame sort animations, WYSIWYG charts and drag-and-drop flowcharts turn abstract ideas into pictures.
