Mattermark

CPA firms can adopt AI features across browser, accounting, scheduling, email and collaboration tools while independence and due-care review remains manual. The supplied research confirms general compliance vendors but finds no public accounting-profession module for AI-tool and audit-client relationship review. It also says the exact March 2026 regulatory-hook date was not independently verified. The original stage verified one interface. Mattermark cannot compute a universal independence or due-care score. A visited domain, browser extension event, login, enabled feature, licensed product, vendor ownership, engagement use and professional-service conclusion are different facts. The browser surface is purpose-limited, transparent and minimized; it never captures page content, client records, passwords or employee productivity. Vendor and corporate ownership candidates require source evidence and effective dates. Audit-client relationships, affiliate scope, covered members, service type, period and applicable professional rules require firm-owned review. A potential overlap creates a case, not an independence violation. Current professional authorities and qualified practitioners decide applicability, threats, safeguards and disposition. Evidence binder, reviewer approval, peer-review use and regulatory or disciplinary outcome remain separate. The product cannot certify independence, due care, audit quality or a defensible binder, and it cannot block staff or vendors without accountable firm authority.

A CPA-firm independence, quality, risk or technology leader responsible for reviewing AI vendors and documenting professional-policy decisions.
