How DejaVu Works

One clean report from messy trade risk.

DejaVu is built to make the scan feel simple, but the process behind it is layered. The goal is not to throw random data at a trader. The goal is to turn messy signals into one readable report.

01Input cleanupDejaVu first cleans the username or numeric ID, removes noise, checks formatting and prepares it for a safe lookup.
02Identity matchingThe system resolves the target and protects against typo mistakes, short names and lookalike usernames before trusting the input.
03Intelligence checkDejaVu checks its available intelligence layers, compares known records and looks for evidence connected to the target.
04Evidence mergeRepeated evidence gets cleaned, source labels stay private, and the result is compressed into clear public labels instead of exposing internal details.
05Report outputThe website returns confidence, status, scan timing, source status and evidence in a clean report so traders can decide faster.
