Exercise your reasoning before the AI answers
A cognitive fitness coach that prompts you to think first, then compares your reasoning to the AI's. Based on research into cognitive surrender — the phenomenon where AI access causes people to bypass their own analytical thinking.
Automatically detects opinion, analysis, strategy, and decision questions — the types where your own reasoning has the most value.
After you think and the AI answers, get specific feedback: where you were strong, what you missed, and where your thinking diverged.
Say "just answer" or "skip" any time. The skill is a training partner, not a gatekeeper.

Different questions get different coaching prompts
"Before I weigh in — what's your current read on this?"
"Walk me through what you've observed so far."
"What options are you already considering?"
"What are the trade-offs as you see them?"
