I am searching for quite sometime an application which can detect, and convert hand drawn shapes on a computer (using mouse or stylus) to proper shapes. This will make life so much easier for someone who makes architecture diagrams frequently. The closest offering I could find was with iPad 'Shape Recognition'[1]. But the number of shapes it detects is limited. It also does not appear to be really - meant for or integrated with - tools like draw.io.
