A study conducted in November 2025 by Avito and Pravo.ru involving over 500 lawyers revealed that 88% of respondents use AI in their work. While 63% report increased productivity, 84% express concerns about inaccurate responses, and 80% emphasize the necessity of manual verification of AI-generated results.
Testing involved an 88-page PDF document of Sberbank's terms of service, modified with eight specific clauses to evaluate AI detection capabilities. The models Claude Opus 5, Gemini 3.5 Flash, DeepSeek V4 Pro, and the specialized Yandex Neoyurist service were tested using a prompt requiring risk identification and document citation.
Claude Opus 5 identified all seven requested risks and independently detected an eighth, unprompted clause regarding unilateral tariff changes. However, it incorrectly numbered the paragraph. DeepSeek V4 Pro also identified the seven requested risks with accurate citations but failed to detect the unprompted clause.
Gemini 3.5 Flash failed the primary criteria by providing inaccurate citations and referencing non-existent document sections, despite correctly identifying the risk categories. The Yandex Neoyurist service, designed for legal tasks, was the only tool to detect a technical error in the source file's formatting.
BotHub allows users to upload various document formats and offers a Legal Search feature integrated with the Garant database for 3,000 ₽ per month. Yandex Neoyurist provides 20 free requests per month, with additional paid packages available for users requiring further legal assistance.
