Blackbird OSINT

Blackbird checks a username or email address against hundreds of public

sites and shows you which ones have a matching account.

Enter a username or email, and Blackbird queries each site's public

"does this account exist" endpoint directly from your device — the same

public information you'd find by visiting each site yourself, just checked

in parallel instead of one at a time.

FEATURES

- Search by username or email across 700+ sites (social, coding, gaming,

finance, and more), sourced from the open WhatsMyName project

- See results as they come in, filterable by category

- Export results to CSV or PDF

- Optional AI summary of the accounts found (only the names of the sites

where an account was found are sent for this — never the username or

email you searched)

Blackbird does not create an account, does not store your searches on our

servers, and does not track you. It only checks whether a public account

page exists at each site.

INTENDED USE

Blackbird is a tool for people who want to understand their own public

digital footprint, and for researchers, journalists, and security

professionals doing open-source investigation (OSINT). It surfaces only

information those sites already make publicly visible — it does not access

private data, does not bypass authentication, and does not monitor or

track anyone's activity.

This app is an independent companion to the open-source Blackbird CLI

project (github.com/p1ngul1n0/blackbird).
