Ability to reason

Yandex has expanded the capabilities of Neuroexpert and named the key areas of application of the service. The company announced this on July 4, 2025.

The neuroexpert learned to reason, study information on the entire site using one link, better analyze diagrams and graphs, and also began to support collaboration mode. About 350 thousand people use the neuroexpert every month. The most popular topics of requests to the service are education (17.6% of requests), jurisprudence (10.6%), finance (7%), history (4.6%), marketing (4.2%), HR (3.8%).

The neuroexpert will help solve non-trivial problems that require in-depth information analysis. In particular, this is work with large or disparate data, mathematical problems, the development of strategies and plans for its implementation. In reasoning mode, the Neuroexpert analyzes the user's request and the data provided, builds a logical chain, justifies its theses and only then comes to an answer. In this case, you can follow the course of the thought of the service - this allows you to understand its logic, check the reliability of the response and, if necessary, adjust the request.

You can ask the Neuroexpert why the company's market share in a certain segment has decreased, and ask him to propose options for how to fix this. The service will give an answer based on the information provided - for example, on data from the company's website, from its public news and financial reports.

With the help of the Neuroexpert, it is now convenient to analyze information on the site, if it is not known on which pages it is located. Previously, the service studied only the page to which the user gave him a link. Now the Neuroexpert can analyze the entire site or its specific section at once.

For example, the service can be given a link to the company's website and asked to find references to the ESG strategy in public materials. The neuroexpert will automatically analyze everything, including the sections "About the Company," "News," "Reports," and will show suitable mentions on different pages.

The neuroexpert learned to analyze graphs and diagrams files PDF in and DOCX, not just in PPTX. You can ask the service to explain why, judging by the diagram and financial report, the company's costs increased sharply in a certain period. The neuroexpert will compare the schedule with the report and answer - for example: "The growth is associated with the purchase of equipment under the article" Infrastructure. ""

And the service also learned to display formulas and mathematical symbols: squaring, root, fractions, curly brackets and other operations. For example, this is important for engineering companies that work with technical documentation, different formulas, and calculations.

It has become even more convenient to work with the Neuroexpert team - for example, together with colleagues on a general study. The service now allows you to set access levels and participant roles for the project. The project can be made closed, partially available or public. In the first case, only the author sees it, in the second - it can be shared by e-mail, and in the third - everyone who has a link will see it.

Available roles include an editor or member. The first role allows you to edit the project, including changing any settings and access levels. With the second role, you can view the project and ask questions in it.

Product Announcement

Yandex launched in April 2025 a beta version of the Neuroexpert intelligent service, designed for automated work with corporate data. The new product based on artificial intelligence is capable of processing text documents, presentations, tables, as well as audio and video materials, forming a structured knowledge base on their basis. The tool allows users to quickly find relevant information by asking questions about downloaded data in natural language.

According to Yandex, users can upload links from the Internet and files of various formats to the service, and then ask questions in dialogue mode. "Neuroexpert" analyzes content and generates responses based solely on downloaded sources without adding extraneous information.

In the beta version of the service, users can upload up to 25 files and links to one knowledge base. Once the beta is complete, this restriction will be removed. The created knowledge bases can be shared with other users via a link, which resembles the functionality of cloud storage.

In addition to searching for information, Neuroexpert can retell the content of documents, draw general conclusions or comparisons, and also create texts in the desired style based on the downloaded data. The service is available to all users, including Yandex 360 customers.

Neuroexpert uses several company technologies to extract information from various types of documents. The visual-language model finds the necessary data in graphs and diagrams, speech recognition technology is used to process audio and video, and an optical character recognition system works with text on images.

Answers to user questions are generated by the YandexGPT 5 Pro language model - the latest version of the company's large language model. The integration of neural network knowledge and information from downloaded files is implemented using the RAG system (Retrieval Augmented Generation).
