What Is Blackbird? The Open-Source OSINT Tool for Digital Investigations

Discover Blackbird, the free open-source OSINT tool created by Lucas Antoniaci, CTO of Sherlockeye, that lets you uncover someone's digital footprint across hundreds of platforms using just a username or email address.

What Is Blackbird?

Blackbird is an open-source OSINT tool built for the automated collection of public information. Starting from a simple username or email address, it scans hundreds of online platforms — social networks, forums, marketplaces, communities, and more — checking whether the target has registered profiles across those services.

Unlike manual searches on Google or individual social networks, Blackbird centralizes the entire process in a single command, saving hours of investigative work and reducing the margin for human error.

Its main features include:

  • Automated scanning across hundreds of online platforms

  • Result export in multiple formats (PDF, CSV, and JSON)

  • AI-powered analysis that transforms raw data into actionable behavioral insights

  • Simple command-line interface, accessible even for beginners

Blackbird holds an important place in the OSINT tools ecosystem alongside other well-known projects such as Sherlock — but goes further by integrating artificial intelligence directly into the investigation workflow.

Why Use Blackbird for OSINT Investigations?

In OSINT, speed and accuracy are everything. Every minute matters during an investigation, and the ability to correlate profiles across multiple platforms quickly can be the difference between following a lead or losing it entirely.

Blackbird was built with this reality in mind. It does not just locate profiles — it organizes, exports, and interprets the data for you. This makes it especially useful in scenarios such as:

  • Investigative journalism, where verifying the digital identity of a source or subject is an essential step

  • Corporate due diligence, to validate the online identity and reputation of partners, suppliers, or candidates

  • Digital threat analysis, identifying malicious actors or suspicious profiles across multiple platforms

  • Academic research and digital forensics, with structured reports ready for documentation

  • Security teams (Red Team and Blue Team), mapping the digital exposure of individuals and organizations

How to Install and Use Blackbird

Before getting started, you will need Python 3 installed on your system. If you do not have it yet, visit the official website at https://www.python.org or use your operating system's package manager.

1. Installation

Clone the official project repository from GitHub and navigate to the directory:

git clone https://github.com/p1ngul1n0/blackbird
cd

git clone https://github.com/p1ngul1n0/blackbird
cd

git clone https://github.com/p1ngul1n0/blackbird
cd

Then install the required libraries:

pip install -r
pip install -r
pip install -r

The setup is straightforward and requires no complex configuration, making Blackbird accessible even to those just starting out in the OSINT world.

2. Searching by Username or Email

Blackbird offers two main search methods:

By username:

python3 blackbird.py -u
python3 blackbird.py -u
python3 blackbird.py -u

By email address:

python3 blackbird.py -e
python3 blackbird.py -e
python3 blackbird.py -e

Within seconds, the tool begins its scan and returns found profiles in real time, showing which platforms have an account registered under that username or email.

3. Exporting Results

One of Blackbird's greatest advantages for professional investigations is its flexibility in exporting data. Results can be generated in three distinct formats depending on the purpose of the investigation:

PDF export — ideal for formal reports and documentation:

python3 blackbird.py -u johndoe --pdf
python3 blackbird.py -u johndoe --pdf
python3 blackbird.py -u johndoe --pdf

CSV or JSON export — perfect for integration with other tools, spreadsheet analysis, or feeding intelligence systems:

python3 blackbird.py -u johndoe --csv
python3 blackbird.py -u johndoe --json
python3 blackbird.py -u johndoe --csv
python3 blackbird.py -u johndoe --json
python3 blackbird.py -u johndoe --csv
python3 blackbird.py -u johndoe --json

This portability is essential for teams working collaboratively or those who need to cross-reference Blackbird data with other information sources.

4. AI-Powered Analysis

This is one of Blackbird's most powerful and distinctive features. By activating the --ai parameter, the tool uses free artificial intelligence to automatically interpret the collected data and generate a detailed behavioral summary of the target.

python3 blackbird.py -u johndoe --ai
python3 blackbird.py -u johndoe --ai
python3 blackbird.py -u johndoe --ai

The AI-generated analysis goes far beyond a simple list of profiles. It identifies:

  • Usage patterns and behavior across different platforms

  • Recurring interests and activities of the subject

  • Possible connections between profiles and communities

  • Risks and points of attention relevant to the investigation

This intelligence layer transforms raw data into actionable intelligence, reducing analysis time and significantly increasing the depth of the investigation. For analysts dealing with large volumes of information, this feature represents a meaningful qualitative leap.

Blackbird vs. Other OSINT Tools

The OSINT tools ecosystem is rich and diverse. Projects such as Sherlock, Maltego, and SpiderFoot are widely used by professionals in the field. So what makes Blackbird relevant in this landscape?

The answer lies in the combination of simplicity, coverage, and integrated artificial intelligence. While many tools require complex configurations, paid subscriptions, or advanced technical knowledge, Blackbird delivers a complete workflow — from collection to analysis — for free, with a low learning curve.

For those taking their first steps in OSINT, it is a powerful entry point. For experienced professionals, it is a complementary resource that accelerates steps that would otherwise consume significant time.

Blackbird and Sherlockeye: From Open Source to Enterprise-Grade OSINT

Blackbird is a community project created by Lucas Antoniaci and supported by Sherlockeye — a company built around the belief that powerful investigative tools should be accessible, transparent, and effective.

But if Blackbird is the open-source starting point, Sherlockeye's platform is where professional-grade OSINT truly begins.

While Blackbird focuses on username and email lookups via command line, the Sherlockeye platform takes digital investigation to another level entirely. It offers reverse lookup across 800+ open sources, covering emails, phone numbers, names, usernames, domains, and IP addresses — all from a single, unified dashboard.

Beyond search coverage, Sherlockeye brings capabilities that go well beyond what any command-line tool can offer:

  • Autonomous AI Agent that collects, analyzes, and cross-references public data automatically, delivering new insights without manual effort

  • Blockchain-verified integrity records registered on the Solana network, ensuring full traceability and legal validity for reports, audits, and legal proceedings

  • End-to-end encryption with automatic deletion after 30 days and full compliance with global privacy laws

  • REST API, MCP, and Webhooks for seamless integration into existing workflows and systems

  • Export in multiple formats including PDF, TXT, MD, YAML, CSV, and JSON

Sherlockeye is trusted by law enforcement agencies, investigative journalists, private investigators, cybersecurity teams, financial institutions, and corporate compliance departments — professionals who need fast, precise, and audit-ready results every single time.

If you are ready to move from open-source experimentation to a complete, enterprise-grade investigation platform, Sherlockeye is the natural next step.

Conclusion

Blackbird is a versatile, powerful, and accessible tool for anyone working with OSINT or needing to conduct digital investigations with speed and depth. Its ability to identify online profiles across multiple platforms with just a few commands, combined with organized report generation and AI-powered analysis, makes it a valuable resource for both beginners and experienced professionals alike.

The project is available for free on GitHub:
