Convexly

Convexly measures how well your gut matches reality. Take a 2-minute calibration quiz (1,900+ people have), get your Brier score, then use the decision journal to log predictions, run pre-mortems, and see if you’re actually as right as you think you are. Built for founders, forecasters, and anyone who makes decisions under uncertainty.
