AI REVIEW

Like having a legal assistant review every clause.

Seal reads your agreements before anyone signs — catching non-standard terms, missing signature blocks, and risky language. Think of it as your in-house counsel, without the hourly rate.

  • Redline suggestions on non-standard clauses
  • Missing signature block detection
  • Jurisdiction and enforceability flags
