Model Card: Clausa Legal-AI

Transparency on intended use, training data, performance and limitations of our AI models. Following ML transparency standards (Google Model Cards, HuggingFace).

Version: 0.4 · May 2026 · Pre-Launch

Intended Use

  • Contract analysis: Identification of clause types, risk flagging, source citation — for lease agreements and employment contracts.
  • Supporting legal experts: Efficiency improvement in initial assessment — not a replacement for legal advice.
  • Batch review: Comparison of multiple contracts using defined column templates.

Not Intended For

  • Automated legal advice without human review.
  • Contract types outside the trained corpus (currently: tenancy law, employment law).
  • Court proceedings or formal legal opinions.
  • Decisions with direct consequences without legal expert review.

Training Data

  • German primary sources: BGB, KSchG, TzBfG, BetrKV, MaBV — official statutory texts.
  • Case law: Selected BGH decisions (tenancy law) and BAG decisions (employment law), curated and validated.
  • No training on customer data: Contract documents from pilot partners are not used for training.

Known Limitations

  • Edge cases in unknown clause types: For clauses without clear BGH/BAG precedent, Clausa provides a confidence note — not a binary verdict.
  • Language variants: Strongly dialectal or archaic contract language may impair extraction.
  • New case law: BGH/BAG decisions after the last rule set update are not yet integrated. Update cycle: regular.

Ethical Aspects

  • Human oversight: Clausa is designed as an assistance tool. Every output includes a source reference — so humans can verify.
  • No discrimination: The model is tested for systematic biases, particularly for clauses relating to groups of persons.
  • Data protection: No use of customer data for training. Data location Germany (EU), no third-country transfer.
