What it is
A Python command-line tool and library that checks whether an email address is tied to accounts on more than 120 sites, including Twitter, Instagram, Discord and Adobe. It probes registration, login and password-recovery flows without notifying the address owner, and sometimes returns partially masked recovery emails or phone numbers. OSINT researchers and investigators use it to map a person's online footprint from a single email, either from the terminal or by importing individual site modules into their own async code.
