In short. Seznam's Czech search ecosystem connects sourced search summaries with Seznam AI, an assistant using web search and data from Seznam services.
Definition: Seznam's Czech search ecosystem combines web search with AI services, including linked search summaries and the Seznam AI assistant. These services draw on web pages and, for the assistant, information from Seznam's own services.
Key facts
- Seznam's search summaries announcement, dated 23 January 2025, describes answers assembled from search results, with a source attached to each sentence.
- Its homepage announcement, dated 28 January 2025, describes article summaries using SeLLMa, Seznam's own language models trained further on Czech texts.
- The Seznam AI announcement, dated 15 October 2026, identifies the assistant's previous name as Seznam Asistent and adds Sreality.cz to its connected services.
How do search summaries use web pages?
The January search announcement describes a sequence: Seznam checks whether a query suits summarization, retrieves conventional search results, and extracts relevant content from the top documents. It adds that content to a prompt, the instructions and material sent to a language model. SeLLMa processes the prompt and returns a sourced summary.
Seznam's March explanation, published on 26 March 2025, describes links beside individual citations, beneath the summary and in the search results. For a website review, those are distinct places to inspect when checking how a page appears for a Czech query.
Where does Czech-language content enter the system?
The homepage announcement describes further training of SeLLMa on a large collection of Czech texts, including Czech phrasing and grammar. This documents a language-specific development effort within Seznam's services.
That announcement also describes a homepage feature that reads an individual article and produces a short summary. Another homepage feature explains trending search queries by finding current articles about the topic and generating an explanation from their content. The underlying material therefore differs: one feature summarizes an article, while another uses articles to explain increased search interest.
Which services does Seznam AI connect?
The October announcement describes access to current internet information through Seznam search alongside data from its service ecosystem. It names search, news websites, Zboží.cz, Firmy.cz and the television programme service among existing connections.
Its concrete example combines available properties from Sreality.cz with information about nearby amenities through Firmy.cz. The same announcement lists Mapy.com, Kupi.cz, Sauto.cz and Horoscopes as planned additions by the end of 2026. For businesses reviewing this ecosystem, the documented inputs extend from ordinary web pages to information held in connected Seznam services.
What can a website owner check?
As of 17 October 2026, Seznam's crawler documentation describes SeznamBot as the crawler that finds new pages and updates information about known pages. A crawler is software that visits web pages automatically.
A robots.txt file gives crawlers instructions about fetching pages. Seznam's robots.txt documentation states that SeznamBot respects its rules. This block, taken from its example, prevents fetching paths beginning with /admin:
User-agent: SeznamBot
Disallow: /admin
The file belongs at the website root and its filename uses lowercase letters. Reviewing these rules checks access to the underlying web content used by search.
