The price depends solely on the number of databases, not on which ones are selected. Any of the thirteen is counted as a database: IP Court, Judicial Chamber for Administrative Cases, Judicial Chamber for Criminal Cases and each of the ten commercial cassation districts — Moscow, West Siberian, North-Western, Central, Ural, Far Eastern, East Siberian, Volga-Vyatka, Volga and North Caucasian.
The first three databases added to “Higher Courts” at ₽990 cost ₽500 each; each subsequent database costs ₽200. One database can also be taken without “Higher Courts” for ₽590. The bundle is assembled by ticking boxes in your account, and the price is calculated immediately.
for 30 days, unlimited across all databases in the bundle
In the “Glossa” account, it is paid for together with the bundle in a single payment, but connected using its own address https://glossa-ai.ru/mcp, rather than through the unified database address.

Unlimited across all connectors and bundles No matter how many queries your AI system makes, access is unlimited.
Build your own package in the configurator: employee licenses, a set of connectors and a shared pool of queries—the price is calculated immediately, with volume discounts. Payment by invoice; the company gets— its own account: statistics by code, enabling and disabling codes, and renewal invoices.

One substantive question to the assistant. In response, you receive a complete overview of case law with links to courts’ legal positions and the full texts of judgments. The query balance is shared between the web chat and the Telegram bot.
The web chat and Telegram bot are the ready-to-use CasusLegal assistant. You open lk.casus.legal or the bot @CasusLegalBot, ask a legal question in ordinary language, and receive a ready-made case-law overview with links to judgments. No setup is required; payment is made in packages of queries. This is convenient if you do not work in Claude, ChatGPT, Grok or Hermes.
A connector connects our database directly to your Claude, Grok, Hermes or ChatGPT (as well as Cursor, VS Code and other environments). Once connected, you communicate with your AI system as usual, for any task, and at the right moment it queries the CasusLegal database itself and provides actual case law with links—directly within your conversation, without switching. Payment is by fixed subscription; we do not limit the number of requests. This is for those who already work in Claude, ChatGPT, Grok or Hermes and want them to rely on genuine case law rather than inventing it.
You do not need to pay for the package eight times. In your account (“Bot and web chat”) each package has a field “Packages”: enter 8 and receive 200 queries in a single payment of ₽15,920. In the Telegram bot, the same is done using the buttons ×2 ×4 ×8 ×20 on the purchase terms screen.
Volume discount. It is already built into the package of 25 queries: ₽79.6 per query versus ₽89 in the package of 10—a −11% discount. The price per query does not decrease further: each answer is a full model run across the entire database, and its cost does not fall because more queries are purchased. Therefore, 200 queries cost ₽15,920—exactly 8 × ₽1,990.
If you need queries for several employees, count not packages, but corporate access: there is a shared pool of requests for the entire company, separate codes for employees, an invoice and closing documents issued to the legal entity.
No. Three free requests and three days of the connector are available immediately after signing in via Telegram — no card required.
By Russian bank card through YooKassa — from the personal account or directly in the Telegram bot. Companies are issued an invoice by the legal entity.
If the payment fails with the message “technical error,” start a new payment from the account (you cannot retry using the previous link) and select SBP: it is processed through the bank’s app and appears on the form when auto-renewal is disabled.
The website, personal account, payment and connectors work from Russia without a VPN. The personal account is at lk.casus.legal, and the Telegram bot is at @CasusLegalBot.
The login to the account is the same from the storefront and at lk.casus.legal: email and password or Telegram. For companies, the tax identification number and password are used at lk.casus.legal/corp.
From September 28, 2026, each of the ten districts is a separate database
in the modular grid: ₽590 / 30 days on its own or as part of a package with
the “Higher Courts” under the general grid (+1 database — ₽1,490, then +₽500 and
+₽200 per database). “Higher Courts” and all ten districts — ₽3,890; all
13 databases — ₽4,490. Paid districts are connected under one address
mcp.casus.legal/okrug/mcp. The free launch week
for the districts ran from September 21 to 28, 2026.
The KUD connector (criminal cases) is available by subscription, like the other specialized databases: ₽590 / 30 days; a package with the Higher Courts — ₽1,490; all four connectors — ₽2,490. The launch promotion (free week) ended on July 21, 2026.
Auto-renewal is optional. Request packages for the chat and bot do not involve automatic charges at all: they are one-time purchases.
Yes, the set of connectors is configured in the personal account, in the “Connectors” section. A database can be added immediately: you pay the difference, and the remaining value of the current subscriptions is credited toward the new plan. Downgrades take effect from the next period, while the paid term remains fully preserved.
