Statute, case law and public registers in one question. Every statement has a source you can open.

In force, amended or repealed: the system says so before it cites.
Supreme court, appellate and regional courts and constitutional decisions in one search.
EUR-Lex and the Strasbourg case law, in the same answer as the domestic rule.
Company register, title deeds, authority databases, bar and notarial rolls, web search.
Deadlines, duties, fees, default interest, GDPR fines; court forms filled in.
Ask it to attack its own answer, and it shows you the weak points too.
Our own DOCX engine. An edit is a real tracked change, and saving returns the original file, not a retyped copy.

Not coloured text but real Word tracked changes: accept, reject or filter them in Word.
The difference between two versions on one page, paragraph by paragraph.
Only the marked paragraph is touched; the rest of the file stays as it was.
Comments, revision history, hidden metadata and author names removed.
Reads the draft through: missing clause, contradiction, typo, wrong reference.
Firm templates and house style; spreadsheets; PDF tools, translation, anonymised export.
Untouched parts go back into the file unchanged: styles, numbering, headers, fields.
Clausis works where the document is born: in the contract, in the email. It checks, corrects, anonymises and replies, with the source.
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.
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.
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.
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.

The firm's whole archive, processed.
Yours alone. The model never trains on it.
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.
Drag-and-drop, bulk upload, or Google Drive, OneDrive, SharePoint, Dropbox, Notion: the 2019 file processed exactly like yesterday's.
PDF, Word, legacy .doc, e-signed (ASiC) containers, scans with Hungarian OCR: all indexed passage by passage.
The firm's own material answers the question, with a citation that opens the document at the right place.
What the firm has decided once, the system knows in every conversation; the draft follows the firm's own patterns.
Every query is filtered by organisation; folder- and group-level access decides who sees what. Never another firm.
EU data centre, encrypted in transit and at rest; deletable at any time, and never used to train the model.
No separate system to maintain. The conversation opens the matter, records the deadline and issues the invoice.

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.
Identification, beneficial owner, conflict check, official identity verification and the registers that go with them: all in the same thread.
What the system establishes in the thread lands in the calendar and the deadline diary. The phone shows it under Today.
Time entries build from the work; the invoice goes to Billingo or Számlázz.hu. Issuing it requires your approval.
Your firm's positions in one grid: what you accept, what you do not, and which statutory section it rests on. What is mandatory law never goes to negotiation, and you are told when the section beneath it changes.

Dozens of documents, the same few questions. The answers assemble into a table, each cell carrying the reference that stands in the document.

Dozens of documents, the same few questions: the answers assemble into a table, each cell carrying its reference.
The firm's positions anchored to statutory sections; you are told when the law beneath them changes.
The firm's knowledge lives in folders, and each folder decides who may see it.
Email, calendar, cloud storage and invoicing in one place; custom connections too.
The regulation's full text set in the legal pages' own type, in two views.
A living catalog of court forms, filled straight from the conversation.
Transcripts and summaries of hearings and dictation, in the Vault.
A client's own sign-in, with documents, deadlines and status reports.
Search flags repealed statutes and points at their successors.
Document templates learn the firm's own style, not a generic one.
Across the whole Hungarian corpus, with clickable sources and a shorter wait.
VII · The vision

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.
To the strictest standards: ISO 27001, GDPR, EU data centres. The models do not learn from your documents.
Security documentationClausis is ISO 27001 certified: it operates to the internationally recognised standard for information security management.
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.
