HOW IT WORKS

Every case presents a real-world claim — the kind you'd see on Reddit, in the news, or at the dinner table. You analyze it using a 5-step protocol:

1. Identify the Claim — What exactly is being stated?
2. Check the Evidence — What proof is offered or missing?
3. Test the Logic — Does the reasoning actually follow?
4. Scan for Assumptions — What's being taken for granted?
5. Consider Alternatives — What else could explain this?
6. After each step, you get immediate feedback explaining why your answer was strong, partial, or off-track. No lectures. No textbooks. Just pattern recognition that transfers to real life.

WHY SHRPR

Iron sharpens iron. The best critical thinkers aren't born sharper — they practice against hard material. SHRPR is built on the belief that the mind responds to the same principles as the body: consistent reps, progressive difficulty, and honest feedback.

From the person who almost shared it — to the person who already knew not to.

Be the sharp one.
