Contract Summarisation and Compliance Checking

Before sending a document for signature, run it through Zignature's AI to get a plain-language summary of key terms, identify unusual clauses, and check for common compliance issues. Signers can also see the AI summary before signing.

  • Key terms summary — Core obligations, payment terms, termination clauses highlighted in bullet points.
  • Unusual clause detection — AI flags non-standard or potentially risky clauses for legal review.
  • Signer-facing summary — Optionally show signers a plain-language summary before they sign.

FAQ

Frequently Asked Questions

Everything you need to know about the Claude integration.

Which version of Claude does Zignature use?
Zignature uses Claude Sonnet for complex tasks (template generation, compliance checking) and Claude Haiku for faster tasks (field detection, summarisation) — automatically selecting the right model.
Is my document content sent to Anthropic?
Document content processed by Claude AI follows Anthropic's API data handling policy. Zignature uses the API, not the consumer product — content is not used for training.
Can Claude generate templates for any type of document?
Yes. Claude can generate templates for NDAs, service agreements, employment contracts, lease agreements, SOWs, purchase orders, and most other common business documents.
How accurate is AI field detection?
High-confidence fields (signature lines, date fields) are placed automatically with 95%+ accuracy. Lower-confidence locations are flagged for manual review.
Can I use Claude through my own Anthropic API key?
Zignature's AI features use Zignature's Anthropic integration — no separate API key needed. Enterprise customers can configure their own Anthropic API key for data sovereignty requirements.
