A working model of the engine. The app adds nickname timelines, Compare Selected across any number of proposals, and export into your firm’s template.

Save it, compare it, stack the next round.

The calculator on this page does not keep a history. The app does — every proposal on the requirement, side by side, with the nickname timeline underneath.
