Tom's OSINT Workbench is a powerful, free, and entirely offline OSINT (Open Source Intelligence) investigation software designed for Windows. It provides a structured approach to case management, allowing analysts, journalists, and security researchers to track and visualize connected entities directly on their own machines, ensuring complete data privacy.

Key Features:

Entity-centric case management for 9 types (people, domains, emails, etc.) with typed relationships and confidence levels.
Interactive visual link analysis using force-directed or hierarchical graph layouts.
Automated data extraction from URLs, including RDAP, DNS, IP geolocation, Shodan, and crt.sh lookups.
Point-in-time snapshots and diffing to track changes in entities or cases over time.
One-click export of self-contained HTML reports with embedded graphs and AI analysis prompts.
Built-in directory of 94 curated OSINT resources, expandable by the user.
Private by design: all data stored locally in a portable SQLite file, with no telemetry or cloud accounts.

Use Cases:

This robust desktop application is ideal for professionals conducting in-depth investigations where data privacy and structured organization are paramount. Journalists can use it to map out complex networks of individuals and organizations, tracking their digital footprints and documenting evidence without fear of data breaches or vendor access. The snapshot feature is invaluable for monitoring evolving stories or tracking changes in public records.

Security researchers and analysts can leverage Tom's OSINT Workbench for threat intelligence, incident response, or vulnerability research. By pasting domain or IP addresses, they can quickly gather critical information like open ports, subdomains, and tech stacks, then visualize how these entities connect to social profiles or other infrastructure. The ability to compare snapshots helps in understanding the progression of an attack or the evolution of an adversary's infrastructure.

Furthermore, anyone needing to perform due diligence, background checks, or simply organize vast amounts of public information will find this tool indispensable. Its offline nature means investigations can be conducted securely, even in sensitive environments, and the comprehensive reporting ensures findings can be easily shared and understood.

Tom's OSINT Workbench is completely free for both personal and commercial use. There are no hidden costs, subscriptions, accounts, or paid tiers required, making it an an accessible solution for all users.

User Experience and Support:

The application features an intuitive, entity-centric user interface with dark and light themes, designed for ease of use. Its 9 investigation tabs provide a clear workflow from dashboard to snapshot diffing. Users can benefit from a comprehensive user guide for walk-throughs and can send feedback directly to the developer.

Technical Details:

Built for Windows 10 and 11 (x64) using C++17 and the Win32 API, the workbench is a single portable EXE with zero dependencies.
