Lekh is an online whiteboard and intelligent diagramming tool available for iPad, iPhone, and Mac. It offers a unique feature where you can sketch shapes with your finger, and the shape recognition technology will seamlessly convert them into precise shapes. In offline mode, users can create high-quality diagrams including flowcharts, block diagrams, system architectures, and mind maps using smart drawing mode or by dragging shapes from the library.

In online mode, Lekh provides a collaborative whiteboarding experience on a shared canvas where multiple users can draw simultaneously. You can store your drawings in the cloud, collaborate in real-time, and share your work with others. The shape recognition engine can identify various shapes and connections, making it easy to create professional diagrams effortlessly.
