The README opens with

Give the next model call the context it needs. Keep the history for later.

Pi-Saver is a dynamic context-filtering extension for Pi Coder that intercepts conversation context before each inference. By using Jev by TypeSafe to instantly evaluate and exclude information in the context history that isn't relevant to your current request, Pi-Saver can save as much as 75% or more on context tokens while keeping your complete session history intact.

It groups history into complete turns, runs those chunks through Jev, and judges what is necessary for the latest user prompt—and what can safely be discarded for this specific call.
