How DejaVu Works
Step-by-step explanation of input cleanup, identity matching, evidence checks, source labels and scan output.
Open guideKnowledge Base
DejaVu is built for Roblox Jailbreak traders who want cleaner information before risky trades. These pages explain how the scanner works, how to read results and how to protect yourself when the evidence is incomplete.
Jailbreak trades often involve items that took weeks to earn, so a wrong decision is expensive. The guides below are written for that situation: they cover what a scan result actually tells you, what it does not tell you, how the report system keeps the database current, and what to do when a trade looks risky before it happens. Read the relevant guide before a high-value trade rather than after something has already gone wrong.
