Why this fits
The lawyers use case, in detail.
Legal use of AI detection is rising as courts and regulators address AI-generated filings. Several US courts now require disclosure of AI-assisted content in briefs, and at least one judge has sanctioned lawyers for AI-fabricated case citations. AI Checker is used by law firms in three ways: vetting incoming work product from associates and external counsel, due diligence on contract drafts in M&A workflows, and authenticity verification on deposition transcripts and statements. The sentence-level breakdown is especially valuable in legal contexts because partial AI use is common (associates drafting standard sections with AI assistance is increasingly accepted), but fully AI-generated argumentation is generally not. Our enterprise tier includes audit logging for compliance documentation, plus an on-premise deployment option for firms with strict data handling requirements.
