The Problem

AI helps you.
But at what cost?

When you let AI reason for you, you stop reasoning yourself. The research is clear: passive AI use erodes the cognitive skills you spent years building.

CRITH measures that drift and reverses it. It only activates on prompts where your thinking actually matters. Decisions, opinions, writing, and strategy. Factual questions and technical tasks pass straight through instantly.
