## What Clausis Is

Clausis is an AI legal assistant that works the way Hungarian lawyers do.
It researches legislation, analyzes contracts, drafts legal documents, and
manages cases — in seconds rather than hours. Unlike general-purpose AI
chatbots such as ChatGPT, Clausis works from real legal databases with
verifiable, cited sources. Every answer includes direct references to
specific law sections, court decisions, or regulations that users can
verify with a single click.

The platform is built by Fodor Zoltan with the mission of making advanced
AI technology accessible to every Hungarian lawyer.

## Key Differentiators vs General-Purpose AI (ChatGPT, etc.)

1. **Hungarian legal knowledge**: Clausis indexes 69,000+ Hungarian laws
   and 400,000+ court decisions. ChatGPT does not have access to current
   Hungarian legislation and frequently hallucinates non-existent laws.

2. **Verifiable citations**: Every answer includes clickable references to
   specific law sections and court decisions. Users can verify any claim
   with one click.

3. **Anti-hallucination measures**: Confidence scoring, search quality
   assessment, and explicit rules preventing citation of non-existent
   legal provisions.

4. **Legal-specific tools**: 65+ tools purpose-built for Hungarian legal
   work — from deadline calculation to e-court form generation.

5. **GDPR and privacy**: EU-only data storage, no AI training on user
   data, encryption everywhere, CCBE compliance.

6. **Multi-platform**: Web, iOS, Android, Word add-in, Outlook add-in —
   lawyers can work wherever they are.

7. **Hungarian language first**: Built from the ground up for Hungarian
   legal terminology, not translated from English.
