Risk Analysis Team

A ready-made team has appeared in Neurourist to analyze the risks associated with changing the VAT rate from 20% to 22% from January 1, 2026. It allows you to significantly reduce the time for checking documents and minimize the risks associated with late correction of documentation. Yandex B2B Tech announced this on December 18, 2025.

The VAT Risk Analysis 2026 team allows you to check up to 10 documents in a few minutes, including contracts, additional agreements and offers, both in text document format and scans, for example, in PDF. It is enough for the user to download the files, and the service will highlight the wording related to VAT in them, draw up a table with a list of such wording, and then give an opinion on whether they create risks for the company.

{{quote 'For Russian entrepreneurs, the changed VAT rate is a revision of the terms of dozens, hundreds of contracts with suppliers and customers. Manual verification of each document by a lawyer will take 20-30 minutes. But now you can check the documents many times faster without losing quality, - said Roman Yankovsky, development manager of Neurourist at Yandex. }}

The increase in the basic VAT rate from 20 to 22% is a major change that will affect many aspects of our work. It is especially important to note that the new rate will apply to shipments completed from 2026. That is, the key criterion in determining the tax rate will be the shipping date, not the moment of payment. That is why companies need to carefully analyze all contracts and other documents in order to minimize risks and be ready for new conditions, "said Mikhail Kiselev, tax director at Yandex.

Presentation of the "Neurourist"

Yandex B2B Tech November 20, 2025 presented its specialized AI assistant - Neurourist. It helps lawyers solve routine tasks and save time. It is already used on a permanent basis by about 75% legal of the department's employees. Yandex The assistant takes on part of the daily work of the lawyer. Measurements have shown that it speeds up work with contracts by 1.5 times, and search and analysis of information by 3 times.

AI-helper answers as a qualified lawyer. It will be useful for consultations, research, self-testing and more. For example, if you ask him: "Can the general director work in three part-time jobs?" - he will give a detailed answer that takes into account legislation, judicial practice and clarification. Ministry of Labour and Social Protection Russia The answer will be supported by links to materials in the Guarantor system.

In addition to the "Guarantor," the Neurourist is able to work with user files. These can include documents, PDF files, presentations, images, audio and video recordings. For example, you can show him mock-ups of advertising banners and ask him to check them for compliance with the law.

The neuro-lawyer understands the most demanded areas of law: labor, corporate, information, compulsory and advertising, and also gives answers to the legislation on the protection of consumer rights and intellectual property. The assistant is based on the Alice AI LLM language model. She was further trained by lawyers: they provided sample answers, marked up the data and introduced the Neurourist to the specifics.

The main feature of our assistant is that it was created by lawyers for lawyers and is most adapted for the tasks of Russian users. Unlike generative neural networks of general application, the Neurourist is familiar with the hierarchy of sources of law and takes it into account when drawing up answers. For example, he knows that the Decisions of the Plenum of the Supreme Court take precedence over a single decision of the arbitration court when interpreting a rule of law, and at the same time takes into account the presence of differing judicial practice on the issue, "said Yulia Popelysheva, director of the Yandex legal department.

The assistant not only gives advice, but also helps in applied affairs. For this, built-in AI agents are used. For example, there is an agent for analyzing contracts - this is one of the most common legal tasks. Another agent allows you to map two versions of the same document - it will highlight the changes and give comments to them. Also, the Neurourist can be asked to simplify the complex legal text. This will come in handy in situations where you need to draw up a generally understandable explanation for non-lawyers.

AI assistants in pilot mode were tested by about 50 Yandex partner companies. Now the Neurourist is already capable of performing up to 40% of the lawyer's work tasks. Since August 2025, when testing started in Yandex, he issued more than 10,000 answers - 86% of them received a good rating from lawyers.

The neurourist does not just quote norms, but demonstrates an understanding of legal logic. For example, he knows how to highlight factual circumstances that are of legal significance. We noted high quality on typical requests: the answers that the assistant gives can be immediately used in work. We hope that the Neurourist will continue to improve and expand the range of tasks and spheres of law, "said Yuri Donnikov, head of the legal department of the hh.ru.

Each user has free access to 20 requests to the Neurourist per month. The limit can be increased by buying a subscription from the Yandex Cloud marketplace. Organizations have the opportunity to deploy Neurourist on their own infrastructure - according to the on-premises model.
