We describe a prototype toolkit for reasoning about Graphical Interval Logic (GIL) specifications of concurrent systems. GIL is a visual temporal logic that is intended to be more intuitive and easier to use than standard textual temporal logics. The GIL toolkit helps system designers to create graphical specifications of concurrent systems, to verify properties of those systems from their specifications, and to generate models that satisfy the specifications. The toolkit provides a visual interface with specifications, proofs, and models all depicted graphically. The paper describes the toolkit, discusses its implementation, and provides an illustration of its use.>
