Ingatan is a clean, intuitive, and highly flexible memory quiz generator. It is perfect for a huge range of applications, including learning languages, remembering physics equations, labelling anatomical diagrams, practising any type of exam question, and reviewing organic chemistry mechanisms. When asking questions, a bias is placed toward those with a low historical grade. An inline symbol menu makes it easy to insert non-keyboard characters. Questions are intelligently organised into libraries, and libraries into groups, and can easily be shared.
