— Problem

Why generic AI tools fail at contract analysis

Hallucinations on statutes, deadlines and clauses — a single wrong detail can cost millions.

ChatGPT · Mietminderung

Welche Mietminderung bei Schimmel in 30% der Wohnfläche?

Das BGH-Urteil existiert nicht. 50–70% Mietminderung ist völlig überzogen. Eine Halluzination, die Millionen kosten kann.

— Manifest

Clausa is different

01 · Manifest

Industry-sharp

Lease agreements are not employment contracts. Clausa ships with industry-specific rules generic models have never seen.

02 · Manifest

German Law

Trained on BGB, ZPO, BAG case law and industry-specific clause libraries. No US clauses, no English answers.

03 · Manifest

EU Hosting

Servers in Frankfurt am Main. No data trip to San Francisco. GDPR, BDSG and attorney-client privilege are architecture, not add-on.

How Clausa works

Contract Analysis

Clausa reads 200-page contracts in seconds, recognises industry context and delivers precise answers — not Wikipedia summaries.

Clause Review

Compare clauses against market standards, your own contract portfolio or the firm's clause library. Risks are flagged, not hidden.

Source Citation

Every answer with clause reference, statute source and confidence indicator. No black box. You see where the answer comes from.

— The Product

Three Tools. One Contract Base.

Tabular review.

Several contracts at once — parties, terms, clauses in one table. With column presets for each industry.

Assistant.

Question in natural language. Answer with clause reference, statute source and confidence.

Workflows.

Pre-built review paths — Change of Control, GDPR audit, CP checklist. Reproducible, shareable, auditable.

— Differentiation

What sets Clausa apart from ChatGPT and others

Symbolic AI

Neural language models alone hallucinate. Clausa combines them with symbolic rules — deterministic, verifiable, reproducible.

Proprietary Data

Your contracts, clauses and preferences remain your intellectual property. We don't train foundation models on your data.

Human QA

Every answer undergoes quality assurance with legal experts. AI accelerates, humans validate.

Tabular Audit

Compare hundreds of contracts in one table. Parties, deadlines, clauses — structured, auditable, shareable.

GDPR Compliant

Servers in Frankfurt. No third-country transfer. Processing record and DPA in the first pilot week.

Client Segregation

Strict separation of all client data. No cross-contamination, no data leak between customers or industries.

— Manifesto

“Every clause can be read twice — once by language, once by law.”

Every clause carries two meanings: the literal and the legal.

Generic language models read only the first. They interpolate what sounds probable and call it an answer. Law is not probability. Law is structure — statute, subsumption, consequence.

Clausa joins neural language with symbolic rules. Trained on German law. Hosted in Frankfurt. Every answer carries a clause reference, a statutory source, and a confidence score.

We do not build a tool for the quick reply. We build an instrument for the first reading — structured, citable, deterministic. The second reading remains human.

— The three pillars

Architecture, not interpolation

Neural language and symbolic rules, joined by construction. Not by averages.

II.

Determination, not probability

What is not sourced is not asserted. Every answer with citation, statute and confidence.

III.

Complement, not substitute

Clausa does not replace the lawyer. It amplifies them. The final reading stays human.

Not faster. Not cheaper. Only correct.

— Background
