OSINT Powered by AI, Driven by Community
Tesari is an AI Copilot that helps OSINT investigators to collect and analyze open source data by searching and cross-referencing information from social media, digital footprints, beneficial ownership, corporate data, watchlists, court records, news, leaks, breaches, and the web
Sources
Thousands of mapped global sources:
+ structured data
+ unstructured documents
+ multilingual media
+ scattered digital footprint
+ leaks
+ breaches
+ custom web.
Coverage
Beyond-reach sources:
Extensive research capabilities in China and Russia: owners, suppliers, courts.
How it works:
Input:
Investigators provide the subject's name and contextual information to Tesari
Data gathering
Social Media
Web & Media Search
Digital Footprint
Corporate records
Hard-to-reach regions
Beneficial ownership
Watchlists / Sanction list
Data Leaks
Validation
Matshing real and digital Identities matching
Translation
Data cross-matching
Desinformation detection
Structuring
Structure findings
Fact-checking
Referencing
Drafting editable report sections
Work with output:
Use an AI Copilot capable of making changes, rewriting sections, structuring findings into preferred formats, and providing recommendations or answers
01
Investigators provide the subject's name and contextual information to Tesari
02
Tesari searches, resolves, translates and structures relevant data into an editable OSINT report
03
Investigators analyze findings and work with AI Copilot to make changes, delete or add new information
Our guiding principle behind product development:
AI will never replace an investigator’s analytical mind, instinctive judgement, or objective integrity. Tesari exists to automate the painstaking parts of the job, so that investigators can operate without limits.
Use Cases
INVESTIGATIVE JOURNALISM
Journalistic investigations often take days or even weeks to gather data from multiple sources, translate it, and manually check its accuracy. Accessing hard-to-reach information makes the process even slower. Tesari completes this work in minutes by compiling, translating, and cross-referencing data from global registries, leaks, media, and court filings. It supports many languages, applies smart transliteration, and keeps every data point traceable to its source.
Supply chain Security
Global supply chains are complex and opaque, with countless intermediaries and hidden links. Tesari cross-references and validates corporate filings, ownership records, and leaked data, allowing investigators to map supplier and buyer networks, trace the origins of goods, and uncover high-risk connections or violations buried deep within multi-layered supply chains.
Due diligence
Due diligence often takes days or weeks of research to complete a single report. Most companies struggle to access regional data, translate it accurately, cross-reference, validate, and analyze it before starting the report. Tesari compiles all relevant data and delivers real-time insights on individuals and companies, helping organizations make informed decisions with confidence.
Litigation support
Inefficiencies in collecting and analyzing evidence slow legal investigations and due diligence. Tesari streamlines cross-referencing, background checks, and evidence discovery through a single interface integrated with multiple sources.
Insider threats
Social engineering, insider threats, and phishing attacks now account for up to 40% of all security breaches. With Tesari, investigators can assess the likelihood of impersonation attacks through behavioral pattern analysis, target prediction, and suspicious activity monitoring.
Disinformation and influence operations
Disinformation moves quickly across borders, often hidden behind media fronts, shell firms, or digital proxies. Tesari connects media outlets, individuals, and organizations across languages and platforms, enabling investigators to uncover shared ownership, funding links, and coordinated narratives.
Fraud investigations
By cross-referencing publicly available information from social media, news reports, business registries, criminal watchlists, and other open data sources, verify the legitimacy of identities, and identify connections to high-risk individuals or organizations.
Law enforcement
Tesari enables law enforcement to uncover hidden connections in criminal, terrorist, and trafficking networks through AI-assisted data correlation and behavioral analysis. The platform consolidates global open-source intelligence into structured case files, helping investigators identify high-risk actors and act faster with confidence.
Apply for early access
Access is limited given the nature of Tesari’s capabilities. To ensure the platform is used responsibly and securely, we take thoughtful steps to understand each user and organization we onboard.
The first release is open to 100 early adopters, who will join through a brief moderation process. A second round will follow at a later stage.
