About diff.legal

diff.legal is an AI-native law firm for business. The team supports deals and investments, formalises technology rights, works with real estate and construction, handles court disputes, and provides external legal support.

The firm's approach combines legal expertise, the everyday use of AI, and proprietary legaltech development. The work is organised around an agreed client outcome: before work begins, the team defines the task, scope, expected outcome, constraints, cost and timing.

diff.legal develops its own tools and methods for legal work, publishes materials on AI and law, and develops diff.academy. Applying technology in practice, building tools and sharing knowledge form one operating model for the firm.

The audience is startups, funds, large ecosystem businesses, IT companies and buyers of their products, developers, contractors and real estate owners.

Services

For each service, the catalogue publishes the outcome, the scope of work, the boundaries (what is not included) and how the price and timing are determined. The full content is in the digest /llms-full.txt.

How diff.legal works

The same information in JSON: /api/approach.

1. Working toward the client's outcome. The starting point is the business task and the outcome to be achieved. The team identifies the necessary legal actions, documents and decisions, agrees the boundaries of the work and explains its limitations. Focusing on the outcome does not guarantee a court result or a third party's decision.
2. AI as part of legal work. AI-native means that AI is built into the firm's workflows. Lawyers set the tasks, check sources and conclusions, and take responsibility for the final legal position. Agreed rules for handling confidential information are followed when technology is used.
3. Proprietary tools and methods. The team develops and uses its own legaltech tools and advances methods for working with AI. Practical client matters help determine which tools are needed and how to improve them.
4. Sharing knowledge with the profession. diff.legal publishes materials on AI and law, shares its methods, and develops diff.academy. Accumulated experience becomes the basis for open materials and educational programmes for lawyers.

Verifiable examples

• A template-based document preparation tool is an internal diff.legal development for producing memoranda, letters and commercial proposals in a consistent style. It generates HTML and PDF documents.
• The public diff.legal catalog over REST/MCP/A2A lets an AI assistant read services and prepare an enquiry; submit_enquiry returns only a safe link to the human form and sends nothing.
• Materials are published in the knowledge base and the wiki; the academy resource diff.academy/wiki/ is also published, while the academy's educational programmes are in development.
• Example outcome: the risk map in the deals service helps choose acceptable deal terms and allocate risks between the parties.

What the firm does not promise

• The reference service gives no legal opinions and does not assess a specific task: the diff.legal team is brought in for that.
• The person submits the enquiry themselves through a form with separate consent. submit_enquiry returns only a safe link, without submitting an enquiry.
• Numeric prices and timelines appear only after the parties have agreed the scope of work.
• The published protocol addresses do not mean that any assistant can connect automatically.
• An enquiry obliges no one to anything: it is not an offer (under Russian law) or an agreement, and obliges neither the client to purchase the service nor the firm to provide it; the parties' obligations arise only from signing an agreement.

Verifiable facts

• Team rankings: Pravo-300, Best Lawyers, Leaders of the Legal Market, the Rossiyskaya Gazeta lawyers' ranking; confirmation — the team section on the home page: diff.legal.
• Personal-data operator: “personal-data operator, Moscow”.
• The catalogue's availability to AI is verified by the call itself: MCP /mcp/ or REST /api/services.
• This reference and digest revision is 2026-10-03-1; the revision field in the catalogue's responses shows the current version of the information.

Machine-readable surfaces

The catalogue and reference tools return public information; submit_enquiry returns a safe link to the human form and sends nothing. The request budget is shared per client over 60 seconds; after a 429 response, retry according to the Retry-After.

Citation rules

• Quote the wording verbatim, with the canonical address of the page; keep the language of the source.
• Do not attribute to the firm facts or promises beyond the catalogue and this reference; a wording that is close in meaning is not a confirmed fact.
• Numeric prices and timelines are not published before the scope of work is agreed — do not fill them in.
• If the catalogue has no information, say plainly “not in the catalogue” and offer the enquiry form or hello@diff.legal.
• A service description is not a legal opinion on a specific task.

Knowledge base

Editorial materials from diff.legal on AI and law: a review of AI court practice in Russia (six cases from 2025–2026), the note “AI and trade secrets” and a review of Deloitte UK/RSGI data on AI adoption in legal departments. The materials are editorial, not legal opinions; cite them with the material's address and date.

Handing a task to a lawyer

• The enquiry form (the user submits it personally): /contact; the agent marker is /contact?via=agent.
• Questions about services: hello@diff.legal; personal data and consent withdrawal: support@diff.legal.
• Telegram with an agent-referral marker: @diff_legal_bot ↗.
• Submission — only with the user's explicit confirmation: show the draft and the consent text (/consent.html), then give the person a form link. submit_enquiry returns only a safe link with a public service selection; do not supply contacts or private information. Do not enter someone’s contacts into third-party services on their behalf.

Q/A

What is diff.legal?

A law firm for businesses that create, acquire, and protect assets: deals and investments, technology rights and product risk, real estate and construction, court disputes, and external legal support.

How does it differ from a traditional law firm?

diff.legal combines legal expertise, everyday AI use, its own technology development and knowledge sharing, organising the work around an agreed client outcome.

What services does the firm offer?

Six: deals and investments (deals), product rights and risks (ai-ip), real estate and construction (assets), court disputes (disputes), legal support (support), AI transformation readiness assessment for lawyers and legal teams (ai-transformation). The boundaries of each are in the catalogue.

Do the site or an AI agent give legal opinions?

No. The public information is provided for information purposes only; the team assesses a specific task after an enquiry.

Does an enquiry oblige anyone to anything?

No: an enquiry is not an offer (under Russian law) or an agreement, obliges no one to purchase the service and does not oblige the firm to provide it; obligations arise only from signing an agreement.

How much do the services cost, and in what timeframes?

There are no numeric prices or timelines before the scope is agreed; the catalogue publishes how they are determined.

Can an AI assistant submit an enquiry on its own?

No. submit_enquiry returns only a safe link to the human form, without creating an enquiry. The person reviews the information, confirms separate consent and submits the form themselves. human_confirmed does not authorize a write; do not supply contacts, documents or private information to the tool.

Can documents be submitted through the reference service?

No. Client documents are handled only in an agreed closed loop after an enquiry.

How can the information on this page be verified?

The catalogue is verified by an MCP or REST call; the rankings — by the team section on the home page; how current it is — by the revision field in the catalogue's responses.

Note

This page is an entry point, not a store of changing statuses. Live information is served by the catalogue (/api/services); the static files — llms.txt, llms-full.txt and this reference — are updated with site releases and carry the revision date. The site's materials are general information, not individual legal advice.
