AI Copilot for Cross-Border Investigations
Powered by AI,
Driven by Community
Tesari is an evidence-based AI platform built for complex cross-border investigations, removing the need for multiple tools and reducing jurisdictional barriers.
This is the New Era of Investigations
Mission-Critical Intelligence, Delivered Fast
The value isn’t replacing people with speed, but quickly finding the information you need and cutting through massive amounts of data to get a clear picture.
Foundational Intelligence = «Step Zero»
Without step zero, there is no step one or two. This is foundational intelligence that feeds all other workstreams and sits at the very top of the investigative workflow.
Reliability you can stand on
This is not purely an OSINT narrative which although highly useful, rarely qualify as evidence in serious cases. Tesari helps you find solid, verifiable evidence through All-source intelligence that you can rely on.
Jurisdiction-focused
All tools in one
AI Copilot
Fully Traceable
Jurisdiction-focused
Trained to conduct deep searches while considering jurisdictional specifics and accessing unique local sources that were previously hard to reach or unavailable.
Used by top professionals to:
Enhanced Due Diligence
Supply chain security
Third party risk
Investigative journalism
Law enforcement
Litigation support

Tesari helps get investigations off to a flying start by cutting out the repetitive manual slog that is often required at the start of a case. Instead of spending days finding and gathering data from dozens of online sources across multiple jurisdictions, Tesari automates the initial data collection so you quickly have a comprehensive case file as a starting point
Tesari can save an investigator a massive amount of time helping you to generate early momentum in your investigation. However, what makes Tesari so compelling is that it does so with accountability and transparency at its core. Sources are listed so they can be reviewed and it’s made clear when the data is unverified and needs more work. Output is already well structured and professionally presented, which again saves time on reformatting when you are preparing your case report.

Tesari solves one of the biggest challenges in investigations: turning complex data into clear, usable intelligence. The platform is genuinely user-friendly, and the output reports are well structured, making them suitable for both analysis and evidential use.
What really sets Tesari apart is how closely the team listens to users. They actively work with analysts and investigators to improve and keep the tool updated so as to ensure i meets real operational needs and the intelligence and evidential standards required for formal proceedings.

I have been using Tesari AI within my investigative workflow, particularly for complex network analysis. It genuinely adds value for me during the collection and processing phase of the intelligence cycle. It helps turn large volumes of messy, unstructured information into something far more digestible, especially when I’m connecting narratives, timelines, and relationships across multiple sources.
It’s also been useful for hypothesis testing. When I have a working theory around a network, company structure, or individual, Tesari allows me to interrogate large datasets quickly to identify supporting signals or contradictions, which helps me refine my analytical direction much faster.
Overall, I don’t use it as a replacement for investigative tradecraft, but as an analytical support tool that reduces noise, structures information, and accelerates insight generation in complex investigations.

Tesari is a unique system that aggregates deep and hard-to-access data from restricted regions, especially China. With Tesari, investigating Chinese companies has become significantly easier.

Tesari is a positive example of how AI does not threaten journalism but empowers it. It gives investigative journalists a powerful boost, allowing them to handle larger datasets, investigate more deeply and quickly, and expand the scope of their investigations.
