Audit is the category where AI has gone furthest and prices have stayed quietest: fifteen of the sixteen tools are quoted after a demo, and AuditFile at $179 per user per month is the posted-price anchor for small firms. The platforms — Caseware, Cloud Audit Suite, CCH Axcess Audit, Inflo, Fieldguide and AuditFile — now carry agents that plan, prepare, review and perform procedures on the firm's own methodology, and the point solutions do one job well: MindBridge scores every transaction for risk, DataSnipper and Trullion match evidence inside Excel, Audit Sight runs deterministic full-population tests, Circit pulls verified bank data straight from the banks, Caseware Validate checks the draft statements, and Suralink, AuditDashboard and Punchcard run the request-to-review workflow.
Every listing names which parts are generative AI, which are machine-learning risk models and which are rule-based, because that distinction matters for audit evidence and several vendors say so themselves. Integrations are listed too: most of these tools plug into Engagement Manager, Caseware, CCH Engagement or Excel rather than replacing them, and the Thomson Reuters stack (Cloud Audit Suite, Audit Intelligence, CoCounsel Audit & Accounting) is listed as separate products because they are sold that way.
