For law firms
Matter, client, deadline and invoice in one place; AML identification and beneficial-owner checks from the conversation; the team working in the same matter.

III · Conversation
Research · In force · Source
Ask. The system goes and checks.
Statute, case law and public registers in one question. Every statement has a source you can open.
What you can ask about
Statutes with an in-force guard
In force, amended or repealed: the system says so before it cites.
Court and constitutional practice
Supreme court, appellate and regional courts and constitutional decisions in one search.
European law
EUR-Lex and the Strasbourg case law, in the same answer as the domestic rule.
Public registers
Company register, title deeds, authority databases, bar and notarial rolls, web search.
Calculations and forms
Deadlines, duties, fees, default interest, GDPR fines; court forms filled in.
A critical reading
Ask it to attack its own answer, and it shows you the weak points too.
IV · Documents
DOCX engine · Tracked changes · Export
A document stays a document.
Our own DOCX engine. An edit is a real tracked change, and saving returns the original file, not a retyped copy.
What the engine does
- 01
Real tracked changes
Not coloured text but real Word tracked changes: accept, reject or filter them in Word.
- 02
Blackline comparison
The difference between two versions on one page, paragraph by paragraph.
- 03
Surgical editing
Only the marked paragraph is touched; the rest of the file stays as it was.
- 04
Clean before sending
Comments, revision history, hidden metadata and author names removed.
- 05
Proofreader
Reads the draft through: missing clause, contradiction, typo, wrong reference.
- 06
Templates, sheets, PDF
Firm templates and house style; spreadsheets; PDF tools, translation, anonymised export.
Untouched parts go back into the file unchanged: styles, numbering, headers, fields.
In Word and in Outlook
Clausis works where the document is born: in the contract, in the email. It checks, corrects, anonymises and replies, with the source.
- 1 · Review
Select the clause, and Clausis tells you what is wrong with it.
It examines the selected sentence against the Civil Code and case law, and puts the source next to the answer. No leaving Word, no copying back and forth.
- 2 · Correction
The correction goes into the text with tracked changes.
The proposed wording appears just as if a colleague had rewritten it: red deletion, blue insertion, one click to accept. The document's formatting stays untouched.
- 3 · Anonymisation
It swaps the names out, and the firm keeps the key.
Company names, addresses and identifiers are replaced with placeholders before anything leaves the machine. The key to reverse it stays with the firm; the model only sees the masked text.
- 4 · Outlook
The reply to the client's email, in the firm's style.
In Outlook, Clausis reads the email, finds the related case and document, and drafts the reply the way the firm would write it. Insert, review, send.
V · Firm memory
Archive · Memory · Style
Firm memory
The firm's whole archive, processed.
Yours alone. The model never trains on it.
The firm's whole knowledge, not a generic model's.
The Clausis knowledge base processes the firm's entire archive: contracts, submissions, judgments, correspondence, old Word files, e-signed containers and scanned paper alike. Every document becomes searchable passage by passage, and the answer cites the firm's own document at a clickable place. All of it stays in the firm's own encrypted store, in an EU data centre; the model never trains on it.
The whole archive, one upload
Drag-and-drop, bulk upload, or Google Drive, OneDrive, SharePoint, Dropbox, Notion: the 2019 file processed exactly like yesterday's.
Scanned paper too
PDF, Word, legacy .doc, e-signed (ASiC) containers, scans with Hungarian OCR: all indexed passage by passage.
Answers from the firm's own documents
The firm's own material answers the question, with a citation that opens the document at the right place.
Remembers, and writes in the firm's hand
What the firm has decided once, the system knows in every conversation; the draft follows the firm's own patterns.
Bound to the firm
Every query is filtered by organisation; folder- and group-level access decides who sees what. Never another firm.
Encrypted in the EU, no training
EU data centre, encrypted in transit and at rest; deletable at any time, and never used to train the model.
Sources
What the answer is made of.
Clausis works from Hungarian and EU law and from court and regulatory practice. Every legal statement carries its source, which opens in one click. Sources for further Central and Eastern European countries are in preparation.

VI · Matter management
Matters · Clients · Deadlines · Billing
The file forms where the work happens.
No separate system to maintain. The conversation opens the matter, records the deadline and issues the invoice.
- 01
The matter opens from the conversation
Ask it to open a matter. The client, the opposing party and the subject come from the context of the thread, not from a form.
- 02
Client intake under the AML rules
Identification, beneficial owner, conflict check, official identity verification and the registers that go with them: all in the same thread.
- 03
Deadline, hearing, task
What the system establishes in the thread lands in the calendar and the deadline diary. The phone shows it under Today.
- 04
Time and invoice
Time entries build from the work; the invoice goes to Billingo or Számlázz.hu. Issuing it requires your approval.

VII · The vision
A standard, not a product
The lawyer brings judgement, strategy and advocacy. Artificial intelligence brings speed, scale and precision. Together they are capable of work neither can do alone: the routine goes to the system, the time goes to the client.
We build Clausis so every lawyer can spend the day on what is truly their work: weighing, deciding and representing the client. The searching, the copying and the deadline bookkeeping go to the platform; the responsibility and the credit stay with the lawyer.
And we do not build it alone. We work with practising lawyers and in-house counsel so that legal work gets a new standard: a verifiable source behind every claim, data that stays in the EU, and technology that serves expertise rather than replacing it.
Security and data protection
To the strictest standards: ISO/IEC 27001:2022, GDPR, EU data centres. The models do not learn from your documents.
Security documentationClausisAI Technologies Kft. operates an ISO/IEC 27001:2022 certified information security management system covering the design, development and support of software solutions.
Data is processed under the EU General Data Protection Regulation, in EU data centres, with a data processing agreement in place.
Clausis is built to the transparency requirements of the EU AI Act and the CCBE's AI guidance: every AI response is labelled, every citation comes from a verifiable source, with human oversight and full protection of legal professional privilege.
