How calls are found and checked

Each transcript was read in full by an AI model to pull out predictions, with the exact quote and timestamp. Each one was then checked with web search against events up to the update date, with sources linked.

How the hit rate works

Spot a mistake? Report it. Hit rate = (came true + ½ partly) ÷ resolved calls. Claims that were already underway when he made them are left out. Open calls haven't reached a verdict; Unresolvable ones are too vague ever to check. Verdicts are AI-assisted and may contain errors.
