Our editorial standards
Source citation
Every factual claim links to a primary source — ABA opinions, court orders, regulatory text, or independent benchmark reports. We do not republish vendor claims as facts.
Editorial transparency
We distinguish independent reporting from vendor-issued content. Source type labels appear on all news items. No affiliate rankings or sponsored profiles.
Freshness signals
All maintained records carry a last-reviewed timestamp. Tool profiles and regulatory tracker entries are updated as the landscape changes — not published once and left to decay.
Professional responsibility
We cover AI tools and technology as information resources. This site does not provide legal advice and does not imply that AI can replace licensed attorneys.
