ConExp-NG is a simple GUI-centric tool for the study & research of Formal Concept Analysis (FCA) that allows you to create formal contexts, draw concept lattices and explore dependencies between attributes. ConExp-NG, whose name stands for Concept Explorer Next Generation, is not an entirely original creation but a modern reimplementation of a similar tool by the name of Concept Explorer with a focus on usability, maintainability and extensibility.
