Dopple
Built at AIE Code Summit 2026 Hackathon · Nov 7, 2026 · San Francisco, CA
Doppel catches bugs in AI-written code, with proof. Paste a function and what it should do. Meta and Google each rebuild it blind from the description alone. All three run on 300 generated inputs, and fixed code (not an AI) casts the vote. If both rebuilds disagree with your code, you get BLOCKED with the exact input as the receipt. Otherwise, VERIFIED.
